Abstract: In an example method, an instruction to begin monitoring incoming traffic of a multicast data flow is received by a router. The instruction is received from a downstream router. The example method further includes monitoring incoming traffic of the multicast data flow. At least partly in response to determining that an expected amount of the incoming traffic of the multicast data flow is being received at the router, reporting to a network administrator device, a location of the router in the multicast data flow. Further, at least partly in response to determining that an expected amount of the incoming traffic of the multicast a data flow is not being received, sending, by the router and to an upstream router, an instruction to begin monitoring incoming traffic of the multicast data flow.

Abstract: A method is performed at a router on a multicast configured to forward a multicast flow. The method comprises: in response to receiving, from a controller connected to the multicast path or the multicast path, an enable command to enable statistics tracing for the multicast flow, determining whether the router has sufficient resources to perform statistics tracing; and when the router has the sufficient resources: responsive to the enable command, enabling statistics tracing to collect statistics for the multicast flow; generating a first request to include the enable command and the statistics; and forwarding the first request towards the controller.

Abstract: In one embodiment, a method by a router in a multicast network for multicast mtrace extension to trace one or more any-source multicast (ASM) sources includes transmitting a mtrace (*,G) route to a last hop router, receiving an active source list, and creating a mtrace (S,G) route for a rendezvous point (RP) to initiate based on the received active source list.

Abstract: In one embodiment, a method by a router in a multicast network includes receiving a multicast trace query comprising a data packet, editing the multicast trace query to include data corresponding to the data packet, transmitting the edited multicast trace query to a subsequent router, transmitting a first message indicating the edited multicast trace query was transmitted to the subsequent router, and starting a timer for a determined period of time.

Abstract: A communication pathway between a plurality of network nodes within a network is established. A DIS election operation is executed to determine a first network node among the plurality of network nodes as the DIS for the network and creating a first pseudo node for the first network node, and with each network node of the plurality of network nodes, determining whether the connectivity between the first network node and the other network nodes of the plurality of network nodes within the network is in a synchronous state with the adjacencies with the other network nodes of the plurality of network nodes within the network.

Abstract: A communication pathway between a plurality of network nodes within a network is established. A DIS election operation is executed to determine a first network node among the plurality of network nodes as the DIS for the network and creating a first pseudo node for the first network node, and with each network node of the plurality of network nodes, monitoring connectivity between the first network node and the other network nodes of the plurality of network nodes within the network, and monitoring adjacencies with the other network nodes of the plurality of network nodes within the network. Whether the connectivity between the first network node and the other network nodes of the plurality of network nodes within the network is in a synchronous state with the adjacencies with the other network nodes of the plurality of network nodes may be determined.

Abstract: The present disclosure relates to a diagnostic tool, and, more particularly, to a diagnostic tool for analyzing and using the results of a flow mediated dilation test.

Abstract: A method for discovering context using a dataplane programmability protocol. The method includes establishing communication with a network device via a dataplane programmability protocol, sending a context monitoring request, via the dataplane programmability protocol, to cause the network device to perform context monitoring, and in response to the context monitoring request, receiving a context update, via the dataplane programmability protocol, from the network device.
