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 system and method for handling multicast traffic in Ethernet Virtual Private Network multi-homed networks includes receiving a first route table for a first route, determining that the first route table is associated with another peer device in the multi-home network, generating a second route table for a second route, determining a route to transmit data and the determined route is the first route or the second route based on the first preference value and the second preference value, and transmitting the data using the determined route.

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 method comprises, at a first router configured to perform Bit Index Explicit Replication (BIER) for forwarding of multicast packets in a network, storing configuration information that indicates that the first router belongs to multiple subdomains of a BIER domain, and is able to forward the multicast packets for a virtual private network on the multiple subdomains. The method further comprises, during an auto-discovery procedure, generating an auto-discovery message to include an auto-discovery route and route attributes that indicate the multiple subdomains, and sending the auto-discovery message to a second router of the virtual private network the network.

Abstract: The present disclosure is directed to systems and methods for logical flow aggregation for fragmented multicast flows, the methods including the steps of identifying a plurality of fragmented multicast flows that are logically related as a single flow in a multicast network; generating a plurality of multicast joins associated with the plurality of fragmented multicast flows, wherein each multicast join of the plurality of multicast joins includes a join attribute comprising a common flow identifier that identifies the plurality of fragmented multicast flows as logically related; and selecting a reverse forwarding path toward an upstream device for the plurality of multicast joins.
