FORCED UPGRADE FOR AIRGAPPED NETWORK MANAGEMENT SYSTEM
A forced upgrade technique for airgapped network management system (NMS) deployments utilizes a package upgrade record. The package upgrade record includes metadata about a target major version of a software package for the NMS deployment, and is generated by an update server that is airgapped from the NMS deployment. A control server of the NMS deployment determines whether the package upgrade record has been provided to the control server. Access to a user interface of the control server is denied in response to the package upgrade record not having been provided to the control server within an upgrade check window, while access to the user interface of the control server is permitted in response to the package upgrade record having been provided to the control server. Additionally, the NMS deployment may be forced to upgrade the software package to the target major.
G06F 21/57 - Certifying or maintaining trusted computer platforms, e.g. secure boots or power-downs, version controls, system software checks, secure updates or assessing vulnerabilities
A switch in a first network is provided. During operation, the switch can learn a media access control (MAC) address of a packet from a second network via a first port. The MAC address can be learned in association with an aggregate virtual local area network (VLAN) configured on the first network for traffic from the second network. The switch can inspect the packet to determine an external VLAN configured on the second network. The switch can send, via the first port a packet on the external VLAN. The source and detector addresses can be a local address. The destination address can be a multi-destination address. The switch can identify the local address as the detector address in a packet received from a second port coupling the second network, identify a loop in the second network in association with the external VLAN, and disable transmission via the second port.
A switching fabric uses traffic congestion information to inform its opportunistic use of non-minimal routes. An ingress port of a network switch collects traffic congestion information from the egress ports of the network switch. The traffic congestion information includes minimal and non-minimal route congestion metrics for the egress ports. Candidate egress ports for forwarding a packet to a destination node are identified. One of the candidate egress ports is selected based on the traffic congestion information. The selection process is biased to prefer some candidate egress ports over others. Particularly, the candidate egress ports that provide non-minimal routes to the destination node and have high minimal route congestion metrics are disfavored by the selection process.
In some examples, a system dynamically assigns, based on one or more factors, tunnels of an underlay and overlay network to a plurality of broadcast groups, where the one or more factors include a factor relating to an operation in the underlay and overlay network, and where the dynamic assignment of the tunnels to the plurality of broadcast groups includes modifying an assignment of a first tunnel from a first broadcast group to a second broadcast group of the plurality of broadcast groups.
Systems and methods are provided for customized grouping of end user devices using a new group identifier tag (GIT) in addition to role-based access (e.g., administrator or guest) and device identifier access (e.g., IP or MAC address). Two components may be implemented at a network access device, including a data plane component and a control plane component. For example, the control plane component may authenticate an end user device, store the MAC and IP addresses for authenticated end user devices, and define access roles for the end user device in the datapath. The data plane component may perform packet processing (e.g., forwarding and policy enforcement) pursuant to previously-defined rules. Whenever a packet arrives at the Network Access Device, the packet is forwarded according to the rules specified by the “role” and GIT present in the entry, allowing for improved processing and scalability of network traffic processing.

One aspect can provide a system and method for emulating the onboarding of networking devices. During operation, a computing device can obtain from a device-activation platform a list of networking devices to be onboarded to a device-management platform method. For a respective networking device on the list of networking devices, the system can collect hardware and firmware information associated with the respective networking device and emulate an onboarding process of the respective networking device using the collected hardware and firmware information, which comprises exchanging one or more handshake messages with the device-activation platform. In response to failing to receive, from the device-management platform, a confirmation message indicating the emulated onboarding process being successful, the system can perform a diagnostic operation to determine one or more potential issues associated with the onboarding process of the respective networking device and display, on a user interface, outcome of the diagnostic operation.
A process includes establishing, by a local activate server agent of a first local branch computer network, a first connection with an activate server of a central computer system.

H04L 41/082 - Configuration setting characterised by the conditions triggering a change of settings the condition being updates or upgrades of network functionality
Systems and methods are provided for validating an identifier using a dynamic matching scheme, including software-defined-matching or hardware-validated-matching. Software-defined-matching may determine whether two identifiers are logically the same when they are both generated by a software application and match each other, and hardware-validated-matching may determine whether the identifier provided by a message stamping process generated by a hardware component of the device matches a second identifier. The flexible validation process can allow the origin of the device to be trusted when the device is sending communications in the network, while detaching the trust from the user that is operating the trusted device or installing software (e.g., an operating system) on the device for temporary use. By disassociating the trust and independently verifying the device separate from the user operating the device, the communications sent and received by the system can be further trusted or distrusted accordingly.
A network management system for orchestrating a network is provided. During operation, the system generates a graph representing the network. A respective vertex corresponds to an entity in the network, and a respective edge indicates a relationship between a vertex pair. The system can determine a first and a second timestamps for a respective edge. The first timestamp indicates a time instance when a relationship indicated by the edge is established. The second timestamp indicates a time instance when the relationship is terminated. The time range between the first and second timestamps indicates an active period for the edge. The system then receives, from an interface of the system, an instruction for comparing the topology, states, and configuration of the network. The system determines the topology, states, and configurations of the network at a target time instance indicated by the instruction by traversing the active edges of the graph.
A network management system (NMS) for provisioning and managing an overlay network is provided. During operation, the NMS can determine that a loop associated with a media access control (MAC) address is detected in the network. The NMS can probe a first switch in the loop by instructing the first switch to observe the MAC address for a predetermined period. The NMS can receive a first message indicating a first set of ports of the first switch observing the MAC address. The NMS can probe an upstream switch reachable via each of the first set of ports by instructing the upstream switch to observe the MAC address for the predetermined period. Here, observing the MAC address at an upstream port of the upstream switch causes further upstream probing. Based on probing the switches in the loop, the NMS can determine one or more loop origination points (LOPs) for the loop.
A system performs a registration process for monitoring a respective address range, by: receiving, from an application, a first command to monitor a first address range in a kernel; registering, in the kernel, the first address range; creating a monitoring state window in the kernel, the monitoring state window indicating that the first address range is valid; and providing, to the application, read-only access to the monitoring state window. The system detects, in the kernel based on a previous state of a mapping of virtual addresses to physical addresses, a change associated with a memory mapping of a second address range. The system updates the monitoring state window by invalidating address ranges overlapping with the second address range. Responsive to the first address range being valid, the system bypasses the registration process for the first address range.
In some examples, a system executes a monitor separate from an operating system (OS) that uses mapping information in accessing data in a physical memory. The monitor identifies, using the mapping information, invariant information, that comprises program code, of the OS without suspending execution of the OS, the identifying comprising the monitor accessing the physical memory independently of the OS. The monitor determines, based on monitoring the invariant information of the OS, whether a security issue is present.

DECOUPLING CONGESTION MANAGEMENT STATE AND CONNECTION MANAGEMENT STATE IN HIGH PERFORMANCE COMPUTING
A first network endpoint establishes a connection with a second network endpoint by transmitting a control packet including a first identifier associated with the connection and the first network endpoint. The first network endpoint stores, in a first data structure based on the first identifier, a first connection state associated with the connection and stores, in a second data structure based on the first connection state, a first congestion state associated with the connection. The first network endpoint identifies, for a data flow associated with the first identifier, a congestion state corresponding to the data flow, by: obtaining the first connection state by searching the first data structure based on the first identifier; and identifying the first congestion state by searching the second data structure based on the obtained first connection state.
One aspect can provide a system and method for selective data forwarding in a multicast network. During operation, a querier router in the multicast network receives, at a first port of, a query-response packet from a network device in response to an all-host query sent by the querier router and add the first port to a port list comprising a number of ports coupled to non-querier devices in the multicast network. In response to receiving a multicast-join message, the querier router can forward the multicast-join message to the ports on the port list comprising the first port except for a port that receives the multicast-join message. Forwarding the multicast-join message to the first port causes the multicast-join message to be received at a second port of a layer-2 switch, which allows the layer-2 switch to forward unknown multicast data packets to the querier device via the second port.
