Some embodiments described herein provide a combination of a layer 3 (L3) hop with layer 2 (L2) bypass/fail-to-wire in a network device. Specifically, some embodiments place the network device between two routers, thereby becoming a L3 hop between the two routers. The existing route between the two routers is preserved by using L2 bypass through the network device. If the network device fails, then the physical fail-to-wire will be engaged, removing its L3 hop, but preserving the L2 bypass.

Estimating data transfer performance improvement that is expected to be achieved by a network optimization device
Systems and techniques are described for calculating performance improvement achieved and/or expected to be achieved by optimizing a network connection. Network characteristics can be measured for non-optimized network connections. Next, the network characteristics can be analyzed to obtain a set of non-optimized connection groups, wherein each non-optimized connection group corresponds to non-optimized network connections that have similar network characteristics. Network characteristics for an optimized network connection can be measured. Next, a non-optimized connection group can be identified based on the network characteristics that were measured for the optimized network connection. A performance improvement metric can then be calculated based on a throughput of the optimized network connection and corresponding throughputs of non-optimized network connections in the identified non-optimized connection group.

Systems and techniques are described for compressing strings by using a tree data structure. Specifically, for each string in a sequence of strings, the embodiments can traverse the tree data structure by matching characters of the string with characters associated with nodes of the tree data structure until either (1) all characters in the string have been processed, or (2) a current character in the string does not match a corresponding character in a current node of the tree data structure. Next, a first node identifier associated with the current node can be returned if all characters have been processed. Otherwise, a new node can be created in the tree data structure to store the remaining characters in the string, and a second node identifier associated with the new node in the tree data structure can be returned.

Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.

Systems and techniques are described for applying a set of policy rules to network traffic. During operation, conditions specified in the set of policy rules can be evaluated, wherein each condition is a logical expression defined over a set of variables, and is evaluated by substituting values of the set of variables associated with the network traffic into the logical expression. Next, a subset of policy rules can be selected whose conditions evaluated as true. A highest precedence policy rule from the subset of policy rules can then be identified by applying a set of precedence rules to the subset of policy rules, wherein the set of precedence rules imposes a precedence order on the set of policy rules based on condition categories and condition specificities. Finally, an action that is specified in the highest precedence policy rule can be performed.

Connecting transparent network devices to optimize unidirectional network traffic
Transparent network devices intercept unidirectional network traffic and use bidirectional network protocol messages to discover each other and configure an inner connection. A first transparent network device intercepting unidirectional network traffic between a source and destination will send a bidirectional network protocol message addressed to the destination that includes an indicator of its presence. Additional transparent network devices that intercept this network message each add their own indicator to the message. If no response to the bidirectional network message is received, an error message is received, or a response message is received directly from the destination by one of the transparent network devices, this additional transparent network device deduces that it is the closest transparent network device to the destination and sends a response message addressed to the source that includes an indicator of its presence. The first transparent network device receives the response message and establishes an inner connection.
Systems and techniques are described for performing proxy auto-discovery in an Internet Protocol version 6 (IPv6) network by using the destination options extension header field in the IPv6 header.

Systems and techniques are described for path selection. A packet can be transparently intercepted at an intermediary device. Next, the intermediary device may modify one or more bits in the header of the packet. The intermediary device can then forward the packet to the next hop device. In some network configurations, the modifications to the one or more bits in the header of the packet may cause a downstream device to select a path that is different from the path that would have been selected by the downstream device if the one or more bits in the header of the packet had not been modified. A path selection policy can be used to determine whether or not one or more bits in the header of the packet are to be modified.

Single-ended deduplication using cloud storage protocol
A single-ended optimized storage protocol enables storage clients or other devices to direct a remote data storage to copy data. In response to commands via the protocol, a remote data storage can copy portions of a data stream at the remote data storage to destination storage locations within the same or a different data stream. The protocol may be utilized for optimized transfer of data via a network to a remote data storage. An initial data stream is divided into segments. Redundant segments are removed from the data stream to form an optimized data stream, which is transferred to the remote data storage. Commands are issued to the remote data storage using the protocol to direct the remote data storage to reconstruct the initial data stream at the remote data storage using the optimized data stream and optionally segments from other data streams previously transferred to the remote data storage.

The file creation on remote data storage accessible via a WAN can be optimized by creating temporary files in advance on a remote data storage. The file handles or other file access parameters for these temporary files are cached at a client network location. A file creation request from a client is intercepted at the client network location and one of the cached file handle is returned to the client. This enables the client to immediately write data to the corresponding temporary file, avoiding the delay incurred by communicating the file creation request and its response over a WAN. One or more storage commands are sent to the remote data storage to change the attributes of the temporary file to match those requested by the client, such as the file name, directory, and/or file permissions. File creation requests may be selectively optimized according to rules or criteria specified by users.

Systems and techniques are described for optimizing secure communications. A client can use an authentication protocol, e.g., Kerberos, to authenticate with the server. Specifically, the client can obtain a service ticket from a ticket granting server, and then use the service ticket to authenticate with the server. The server can respond by providing an encrypted session key. The session key can then be used by the client and server to securely communicate with each other. A wide area network (WAN) optimization device described in this disclosure is capable of obtaining the session key without decrypting the service ticket. Specifically, the WAN optimization device can use information other than the service ticket to obtain the session key.
The presently disclosed subject matter includes a device, system and method for monitoring activity at a computerized device, the device running one or more processes, at least one of the processes executing one or more system events being part of an activity. An activity of interest can be identified if system events related to the activity of interest are identified. An activity is monitored at the device using API queries to obtain descriptive information of the at least one respective system event executed as part of the activity. Using non-intrusive monitoring methods which are based on API queries enables to reduce the potential of interference of the monitoring with applications running on the monitored device.

Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated so that users may more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales. When high-level network performance data of interest is selected, corresponding low-level network performance data is retrieved from the appropriate distributed network monitoring locations to provide additional detailed information.
A method and apparatus are provided for scheduling a heterogeneous communication flow. A heterogeneous flow is a flow comprising packets with varying classes or levels of service, which may correspond to different priorities, qualities of service or other service characteristics. When a packet is ready for scheduling, it is queued in order in a flow queue that corresponds to the communication flow. The flow queue then migrates among class queues that correspond to the class or level of service of the packet at the head of the flow queue. Thus, after the head packet is scheduled, the flow queue may be dequeued from its current class queue and requeued at the tail of another class queue. If the subsequent packet has the same classification, it may be requeued at the tail of the class queue or may remain in place for another servicing round.
Systems and techniques are described for load balancing between WAN optimization devices. During operation, a mapping is determined based solely or partially on capacities of a set of remote WAN optimization devices and capacities of a set of local WAN optimization devices, wherein the mapping maps each remote WAN optimization device to a local WAN optimization device. Next, connection requests are directed to WAN optimization devices based on the mapping.

Systems and techniques are described for path selection. A packet can be transparently intercepted at an intermediary device. Next, the intermediary device may modify one or more bits in the header of the packet. The intermediary device can then forward the packet to the next hop device. In some network configurations, the modifications to the one or more bits in the header of the packet may cause a downstream device to select a path that is different from the path that would have been selected by the downstream device if the one or more bits in the header of the packet had not been modified. A path selection policy can be used to determine whether or not one or more bits in the header of the packet are to be modified.

Automatic prompt detection for universal device support
Embodiments provide systems, methods, and computer program products for network management application to automatically determine a session prompt for a network device and perform error handling. After logging in to a network device, the network management application records the first session prompt response. The network management application sends a series of empty carriage returns and random characters and records the session prompt responses. The network management application compares the responses and determines whether the prompt is a static or a dynamic prompt based on the results. The network management application elicits error responses from the network device by sending additional random characters and records the results in an error handling dictionary. The error handling dictionary is used later when running user-provided commands, enabling a determination of whether a command executed successfully.

Managing digital certificates for WAN optimization over content delivery networks
Digital certificates are distributed to WAN optimization modules in organization and content delivery networks to securely optimize network traffic. The content delivery network identifies edge WAN optimization modules for use with each combination of organizations and their cloud services and distributes digital certificates accordingly. Peering digital certificates for establishing inner connections between organization and edge WAN optimization modules are exchanged via one or more management portals. Shadow digital certificates for establishing outer connections between WAN optimization modules and clients are generated in the form of certificate signing requests. Configuration information identifies any additional cloud services associated with a given cloud service and generate corresponding additional certificate signing requests. Certificate signing requests are digitally signed by a certificate signing authority associated with the organization and then returned via the one or more management portals to the allocated edge WAN optimization modules. Digital certificates may be rotated for security purposes.

Persisting large volumes of data in an efficient unobtrusive manner
Embodiments provide a data persisting mechanism that allows for efficient, unobtrusive persisting of large volumes of data while optimizing the use of system resources by the persisting process. In an embodiment, the persisting process includes a self-tuning algorithm that constantly monitors persistence performance and that adjusts persistence time to maintain performance within user-defined criteria. From one aspect, this allows the persisting process to seamlessly adapt to changes in system environment (speeding up persistence during times of low processor usage and slowing down persistence during times of high processor usage) and to reduce or eliminate CPU spikes caused by persisting process. From another aspect, the persisting process results in the data being persisted as quickly as possible given the system constraints, thereby minimizing the possibility of data loss.
Embodiments provide systems, methods, and computer program products for dynamically hooking multiple levels of application code. A server receives identifying information that identifies a target function of a target application to hook. The server pauses a target process of the target application. The server locates the target function within the target application code based on the received identifying information. The server then hooks the located function outside of the target application, thereby creating hooked code during application runtime.
The connectivity information provided by a variety of inference engines is integrated to provide a set of inferred links within a network. A consolidation is performed among inference engines that operate at a base level of connectivity detail to create a model of the network at this base level. The connectivity information provided by inference engines at each subsequent higher level of connectivity abstraction is then overlaid on the base level connectivity. By separately consolidating the connectivity information at each level of abstraction, the rules for dealing with conflicts can be simplified and/or better focused to resolve the conflict. By assuming that the more detailed lower level information is likely to be more accurate, rules can be developed to modify the connectivity models produced by the higher level techniques to conform to the lower level connectivity details while still maintaining the integrity of the higher level connectivity models.

Quality of service for inbound network traffic flows during slow-start phases
An edge network device controls the quality-of-service of incoming network traffic flows by limiting the bandwidth of incoming network traffic flows to create a network traffic bottleneck at the edge network device. The bottleneck ensures that this edge network device may control the quality-of-service of incoming network traffic flows. During a slow-start phase of a network traffic flow, the edge network device adds phantom network packets to a scheduler queue in addition to the actual packets of the network traffic flow. Phantom packets occupy transmission slots during packet scheduling and are discarded when selected for transmission. This limits the rate that actual packets are received and acknowledged by the destination knowledge, thereby preventing the network traffic flow source from increasing the flow bandwidth above the limit of the inbound network connection.
Potential paths between a source and destination of a network are identified based on trace-route information, then filtered to eliminate paths or links that are not supported by ancillary information associated with the network so as to identify feasible/actual paths between the source and destination. The ancillary information includes, for example, routing tables and ARP tables. If a feasible path cannot be identified based on the ancillary information, supplemental information regarding nodes further along the potential path is assessed to provide a basis for inferring the nodes that may provide a feasible path. The determined feasible paths are displayed for review, and provided to serve as filters for subsequent path-analysis tools.

A method and system that takes advantage of processes that are efficient for determining the topology of small to medium size networks to determine individual network topologies for such networks, and then merges these individual topologies into a consolidated topology for the entire network. Each of the processes that determines the topology of the smaller networks provides the determined network topology, as well as a list of factors that may be relevant in the determination of how the given topology might be attached to any other given topology, such as the identification of a node that is not included in the given topology, or other indications of external connections. The merging process is configured to substantially restrict its analysis to these factors, thereby limiting the extent, and therefore the time consumed, by this stitching and merging process.
Content delivery networks may associate each WAN optimized network connection with a specific client-to-cloud-service connection using connection identifiers. When an edge node of a content delivery network receives or intercepts a network connection request from a client device including an auto-discovery indicator from an upstream WAN optimization module, the edge node stores a connection identifier for this network connection. The edge node sends a connection response back to the client device including an auto-discovery response indicator. In response, the WAN optimization module sends one or more inner connection setup messages including the connection identifier to a second WAN optimization module in the content delivery network to establish a direct connection, referred to as an inner connection. The connection identifier is matched with the previously stored connection identifier to associate an inner connection with the network connection between the client and the cloud service.

System for selecting a proxy pair based on configurations of autodiscovered proxies on a network
Network devices include proxies and where multiple proxies are present on a network, they can probe to determine the existence of other proxies. Where more than two proxies are present and thus different proxy pairings are possible, the proxies are programmed to determine which proxies should form a proxy pair. Marked probe packets are used by proxies to discover each other and probing is done such a connection can be eventually formed even if some probe packets fail due to the marking. Asymmetric routing can be detected and proxies configured for connection forwarding as necessary.

Capture, analysis, and visualization of concurrent system and network behavior of an application
A first capture system that captures network communication events related to an application, and a second capture system that captures internal processing events related to the application. A visualization system analyzes the data captured by each of the capture systems, synchronizes and correlates the data, and presents an integrated display of these communication and processing events. In a preferred embodiment, the communicated messages include an identifier of the application, and the processing components also associate an identifier of the application to each recorded processing event. To facilitate the integrated display of the events, the visualization system synchronizes the recorded communication and processing events to a common time base.
WAN optimization devices and content delivery networks together optimize network traffic on both private networks and public WANs such as the internet. A WAN optimization device intercepts and optimizes network traffic from clients within a private network. The WAN optimization device communicates this first optimized network traffic to the nearest edge computer in the content delivery network via a public WAN, such as the internet. This edge computer further optimizes the network traffic and communicates the doubly optimized network traffic via the content delivery network to a second edge computer nearest to the network traffic destination. The second edge computer converts the doubly optimized network traffic back to its original format and communicates the reconstructed network traffic from the second edge computer to the destination via a public WAN. Licensing and configuration portals configure WAN optimization devices for specific network protocols, types of network traffic, applications, and/or cloud services.

Address manipulation to provide for the use of network tools even when transaction acceleration is in use over a network
In address-manipulation enabled transaction accelerators, the transaction accelerators include outer-connection addressing information in packets emitted over an inner connection between transaction accelerators and inner-connection addressing information is added in packets sent over the inner connection. The inner-connection addressing information can be carried in TCP option fields, directly in other fields, or indirectly through data structures maintained by the endpoints processing the connection. Address information can be encoded into header fields originally intended for other purposes but that are unused or encoded into used fields, overlaid in combination with other data that is being carried in those used fields. The existence of inner-connection addressing information in a packet can be signaled by a flag in the packet, by a bit or other designated encoding. The flag can be in an unused header field or overlaid. Where replacement and option addition is needed, swappers and unswappers might be used.

An interactive virtualization management system provides an assessment of proposed or existing virtualization schemes. A Virtual Technology Overhead Profile (VTOP) is created for each of a variety of configurations of host computer systems and virtualization technologies by measuring the overhead experienced under a variety of conditions. The multi-variate overhead profile corresponding to each target configuration being evaluated is used by the virtualization management system to determine the overhead that is to be expected on the target system, based on the particular set of conditions at the target system. Based on these overhead estimates, and the parameters of the jobs assigned to each virtual machine on each target system, the resultant overall performance of the target system for meeting the performance criteria of each of the jobs in each virtual machine is determined, and over-committed virtual machines and computer systems are identified.

Traffic flow inference based on link loads and gravity measures
Traffic flow between each pair of nodes in a network may be modeled based on loads measured at each link and based on gravity measures associated with each node. Gravity measures correspond to a relative likelihood of the node being a source or a sink of traffic. Gravity objectives are assigned to nodes to serve as an objective for a node's performance. These gravity objectives may be based on qualitative characteristics associated with each node. Because the assigned gravity objectives may be subjective, the gravity measures are used to generate a quantitative function for determining whether a network can achieve these gravity objectives. In one embodiment, link loads are allocated to traffic flows between nodes and current gravity measures are determined. Changes to link loads and traffic flows may then be modeled to minimize a difference between the assigned gravity measures and the gravity measures.

The performance of a monitored system is profiled based on sampling a portion of its operations. In one embodiment, the monitored system allocates memory for objects created as instances of classes and automatically performs regular garbage collection to reclaim memory. A variety of sampling techniques are used to minimize the impact on the performance of the monitored system. Characteristic memory utilization patterns can then be estimated for classes based on the samples. The patterns may be presented to a user for review and analysis. Characteristics of the monitored system's performance may be presented in an interactive interface that allows the user to trace the cause of the presented memory utilization patterns, and provides statistics regarding memory allocation and release to guide the user in this analysis.
Individual network activities are correlated to interactions with a target web page to facilitate an analysis of the performance of the web page. This correlation is preferably performed using a combination of heuristics and rules developed to filter network activities into those activities that are likely to have been caused by the particular transaction, and those that are unlikely to be associated with that transaction. The activities that are identified as being associated with the transaction are subsequently organized to identify a time-flow of these activities within the transaction, from which performance statistics can be determined and presented to a user. Because the individual activities within the transaction are identified and time-ordered, an analysis of the effects of each activity on the overall performance of the web page can be performed to identify potential problem areas, or to diagnose reported problems.

A system and method for managing captured network traffic data is provided. The invention comprises a plurality of capture agents, each being configured to capture the network traffic associated with one or more applications. Each application is associated with one or more capture agents according to an application profile that is stored and maintained in a capture server. When analysis of an application's network traffic is required, the capture server contacts the corresponding capture agents according to the application profile. The capture server then effects the identification and archiving of the network traffic that corresponds to a user-defined capture condition. A database at the capture server maintains a record that associates the corresponding network traffic with the user-defined capture condition such that the corresponding network traffic can later be retrieved and analyzed using an analysis engine.

Establishing network connections between transparent network devices
Transparent network devices intercept messages from non-transparent network devices that establish a connection. Transparent network devices modify these messages to establish an inner connection with each other. The transparent network devices mimic at least some of the outer connection messages to establish their inner connection. The mimicked messages and any optional reset messages are intercepted by the transparent network devices to prevent them from reaching the outer connections. Transparent network devices modify network traffic, using error detection data, fragmentation data, or timestamps, so that inner connection network traffic inadvertently received by outer connection devices is rejected or ignored by the outer connection network devices. Transparent network devices may use different sequence windows for inner and outer connection network traffic. To prevent overlapping sequence windows, transparent network devices monitor the locations of the inner and outer connection sequence windows and may rapidly advance the inner connection sequence window as needed.

Quality of service for inbound network traffic flows
An edge network device controls the quality-of-service of incoming network traffic flows by limiting the bandwidth of incoming network traffic flows. To ensure that incoming network traffic classes quickly converge to the desired bandwidth allocations, the maximum bandwidth allocation to each network traffic class is dynamically varied based on current overall usage. The maximum bandwidth allocated to each traffic class at any given moment is the sum of its minimum guaranteed bandwidth and a portion of the available excess bandwidth. Each traffic class' portion of the excess bandwidth is proportional to the ratio between its minimum guaranteed bandwidth and the sum of all traffic classes' minimum guaranteed bandwidths. Phantom network packets equivalent to the difference between each traffic class' allocated and actual bandwidth may be added to its scheduling queue to implement this dynamic variation. Phantom packets occupy transmission slots during packet scheduling and are discarded when selected for transmission.
Serial clustering uses two or more network devices connected in series via a local and/or wide-area network to provide additional capacity when network traffic exceeds the processing capabilities of a single network device. When a first network device reaches its capacity limit, any excess network traffic beyond that limit is passed through the first network device unchanged. A network device connected in series with the first network device intercepts and will process the excess network traffic provided that it has sufficient processing capacity. Additional network devices can process remaining network traffic in a similar manner until all of the excess network traffic has been processed or until there are no more additional network devices. Network devices may use rules to determine how to handle network traffic. Rules may be based on the attributes of received network packets, attributes of the network device, or attributes of the network.
A network capture element is embodied on a virtual machine, and a utility function is embodied on the actual device, preferably within the virtual machine manager. Both the utility function and the traffic capture element are configured to monitor communication events. To minimize the overhead imposed, the utility function is configured to merely store the time that the event occurred on the actual machine, corresponding to an identifier of the event. The network capture element, on the other hand, performs the time consuming tasks of filtering the communications, selectively storing some or all of the data content of the communications, characterizing the data content, and so on. Instead of storing the virtual time that the communication event occurred at the virtual machine, the network capture element uses the identifier of the communication event to retrieve the actual time that the communication event occurred on the actual machine.

A network analysis system provides for a user-definable display of information related to messages communicated on the network. The network analysis system includes one or more display formats that provide a display of message exchanges between nodes of a network, and a display augmenter that provides additional information on the display based on a user-defined visualization. The user defined visualization includes augmenting the display based on user-defined coloring characteristics and/or augmenting the display with user-defined labels. To further facilitate user control of the augmentation of the display, the system accepts user-defined programs for discriminating among messages, for controlling the labeling of messages, and for controlling the coloring of messages and labels. Commonly used user-defined characteristics and labels are stored in a library, for use via a selection from among the library entries.

End-to-end analysis of transactions in networks with traffic-altering devices
In a network that includes intermediary nodes, such as WAN accelerators, that transform messages between nodes, an end-to-end path of the messages is determined. The determined end-to-end path is used in subsequent analyses of message traces, to identify timing and other factors related to the performance of the network relative to the propagation of these messages, including the propagation of the transformed messages. A variety of techniques are presented for determining the path of the messages, depending upon the characteristics of the collected trace data. Upon determining the message path, the traces are synchronized in time and correlations between the connections along the path are determined, including causal relationships. In a preferred embodiment, a user identifies an application process between or among particular nodes of a network, and the system provides a variety of formats for viewing statistics related to the performance of the application on the network.
An application monitoring system autonomously selects routines for performance monitoring based on characteristics of the content of the routines. These characteristics are preferably related to aspects of routines that are likely candidates for performance improvement, such as repetitive loops, event waits, synchronized blocks, and on. Routines that appear to be relatively un-improvable are excluded from initial monitoring, and routines that are subsequently determined to be relatively un-improvable, based on performance analysis and/or user feedback, are excluded from future monitoring. The determination of each routine's candidacy for monitoring is maintained over time, so that each subsequent monitoring session need not repeat the determinations. Changed routines are routinely re-monitored and/or re-assessed to affirm or modify the routine's candidacy for subsequent monitoring.
Relatively small capacity solid-state storage devices (SSD) are combined with larger capacity magnetic disk storage devices for storing storage block write data to ensure data consistency. Write operations are stored in a sequential write buffer in an SSD to guarantee the storage of write data and then copied from the sequential write buffer to the destination address in a magnetic disk storage device. The sequential write buffer store write data in locations corresponding to the order of receipt of write operations. Write data from the sequential write buffer is transferred to the magnetic disk storage device in the same order and a checkpoint index is frequently updated to indicate the completion of some transfers. During system initialization, the most recent value of the checkpoint index is retrieved and used as a starting location for transferring write data from the sequential write buffer to the magnetic disk storage device.
WAN optimization devices and content delivery networks together optimize network traffic on both private networks and public WANs such as the internet. A WAN optimization device intercepts and optimizes network traffic from clients within a private network. The WAN optimization device communicates this first optimized network traffic to the nearest edge computer in the content delivery network via a public WAN, such as the internet. This edge computer further optimizes the network traffic and communicates the doubly optimized network traffic via the content delivery network to a second edge computer nearest to the network traffic destination. The second edge computer converts the doubly optimized network traffic back to its original format and communicates the reconstructed network traffic from the second edge computer to the destination via a public WAN. Licensing and configuration portals configure WAN optimization devices for specific network protocols, types of network traffic, applications, and/or cloud services.

A method and apparatus are provided for distributing or redistributing licenses from a failed or unavailable license controller to one or more backup license controllers. Each controller has an initial count of licenses it can serve or allocate to clients desiring access to licensed electronic content. Each controller maintains a set of data that identifies the initial license counts and that also identifies backup relationships between controllers. Each such relationship for a given controller identifies which controllers will inherit licenses if the given controller becomes unavailable, and how many (e.g., a percentage) of the given controller's license that will be inherited. A redistribution plan for a given controller may have multiple levels, wherein a subsequent level may be applied only if all controllers designated as backups in the preceding level are also unavailable.
Embodiments provide systems, methods, and computer program products for mapping higher-layer circuits, links, flows, and services to lower layer circuit and connection elements to determine utilization of the lower layer circuit elements based on the high-layer traffic. Higher layer configuration data and lower layer configuration data are imported to populate a model. An inter-layer relationship is either directly or indirectly mapped from the higher layers to the lower layer. Once the inter-layer relationship is established, the higher-layer circuits, links, flows, and services are inspected using the lower layer circuit and connection elements. Circuit and packet-based utilization is determined for the lower layer elements based on the higher-layer traffic flows.

Methods and systems for efficient updating of time-aligned graphs in a monitoring system
The present invention relates to displaying data in a time-aligned fashion. A dashboard may have a defined time window and a plurality of graphs for various types of monitoring data metrics. Updates to each of the graphs may occur at different intervals while the graphs stay aligned to the same time window. The updates may be asynchronously received and displayed in the dashboard in real-time or near real-time. The graphs are aligned to the same time window in a dashboard by adding a future time buffer. When the live data reaches the end of the time window, the future time buffer allows a brief overflow period for updates to be added to the graphs while keeping all the graphs on a common time axis. Once the current time reaches the end of the future time buffer, the dashboard is then shifted forward and a future time buffer is added.

A network health monitoring application computes aggregate reports of network health by combining status results from a group of segments to render a summary health status indicative of the entire group. Individual status values result from policies, which monitor various segments and metrics, or performance parameters (such as byte counts or retransmissions), concerned with providing a particular service. The policies form a hierarchy defining the general or specific nature of the segments included in the policy according to a range of attributes, in which the attributes define a scope of the segments included in the policy group. Multiple metrics gathered on each segment allow filtering by polices based on the metric, rather than the attribute (hierarchy level), thus lending a hierarchy filtering based on “vertical” slices of the hierarchy, allowing the user flexibility to filter on specific attribute values while still computing aggregate health at a particular attribute level.

Embodiments provide systems, methods, and computer program products for tracking objects within a domain and their possible changes and genealogy over time. An object identifier and an interval identifier are associated with an object that enters the domain with an unknown set of attributes and genealogy. The object identifier is analyzed to determine whether it is a pre-existing object identifier. A comparison of the interval identifier is performed to determine whether the object is a copy of a prior object. The object identifier is replaced with a new object identifier and the interval identifier reset when the object is new or a copy. Based on the object identifier and the interval identifier, which represents the possibility of change during each interval, information about the tracked object may be derived and analyzed to enhance performance.

Cross-session protocol acceleration and its application to storage area network file systems
Protocol acceleration is performed between clients and servers over a network wherein transport connections are established between clients/servers and/or their proxies for acceleration of traffic that uses certain protocols. A first transport connection for a first application protocol and a second transport connection for a second application protocol can be made between two proxies, wherein a client-side proxy is in communication with a client and a server-side proxy is in communication with a server, and the proxies use information from message payloads flowing between the client device and the server device over the first transport connection for acceleration of traffic over the second transport connection. Examples of transport protocols include a file server protocol and a storage access protocol. Cross-protocol acceleration can be expanded so that information obtained for one client on one protocol can be used to accelerate traffic for another client with the same or different protocol.

Embodiments provide methods for managing data generated by software transactions, such as event tracing software. In one embodiment, data generated by event tracing software is monitored. The throughput of the data generated may then be modulated based on various criteria, such as a target data rate. The throughput target may be specified on a per-system basis or individual basis. Based on the throughput, the level of detail recorded is modulated. Individual processes may determine a limit or quota depending on their contribution to the throughput. In one embodiment, the method calls for a trace are modified with different property specifications to meet a desired throughput of event tracing data.
