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 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.

DYNAMIC BANDWIDTH CAPACITY CONTROL FOR ENTERPRISES
Systems and methods provide an affordable private bandwidth reservation and control solution for enterprises that can be implemented using both 5G and 4G core equipment. Namely, an enterprise can purchase/contract for a pre-determined amount of bandwidth (e.g., 1 Gbps) that a Communication Service Provider (CSP) will reserve for connected client devices of the enterprise that meet a set of criteria defined by the enterprise/CSP: i.e., dynamic bandwidth capacity control (DBCC) group criteria. Client devices that meet this DBCC group criteria may be “bound” to a DBCC group session. If a bound client device no longer meets the DBCC group criteria, the client device may be unbound from the DBCC group session.
