    Abstract: A method comprises, at routers of a network configured to provide connectivity from a multicast receiver to edge routers multihomed to a multicast source of multicast traffic on an Ethernet segment: creating a limited flood domain for the Ethernet segment, wherein the limited flood domain includes boundary routers positioned to make a final decision as to which of the edge routers to send a multicast join for the multicast traffic; by the boundary routers, upon receiving a source announcement that announces the multicast source is active on a particular edge router of the Ethernet segment, locally storing information, provided by the source announcement, which includes a multicast address for the multicast source and identifies a link to the particular edge router; and by boundary router of the boundary routers, upon receiving the multicast join, sending the multicast join to the particular edge router using the multicast address and the link.

    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: In one aspect, a computer-implemented method for redundant multicast groups, includes receiving a request for an element of content from a device, where the element of content is associated with a first source address and a redundant source group identifying multiple servers in a network including the element of content, determining a second source address within the redundant source group has a shorter distance to a location of the device, and routing packets associated with the element of content from the second source address to the device. The method further includes determining the connection has failed, and routing, automatically upon determining the connection has failed, the device to a third source address of the multiple servers, where the third source address is selected according to a server selection policy.

    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 an example method, a network administrative device receives an indication that a multicast data flow is experiencing traffic loss. The administrative device transmits instructions to a last hop to begin monitoring incoming traffic, if the last hop is receiving expected traffic, the last hop sends it location to the administrative device. If the last hop is not receiving expected traffic, it sends instruction to a next upstream device to start monitoring incoming traffic. Based on receiving a message indicating the location of the last hop, the administrative device determines a network fault is occurring at a location of the last hop. Based on receiving a message indicating a location of an upstream device, the administrative device determines a network fault is occurring at the location of the upstream device.

    Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for tracing multicast paths in hybrid networks. A method for tracing multicast paths in hybrid networks includes intercepting, by an edge device, a first multicast trace request transmitted by a first network device that a source device is connected to for tracing a route between the source device to a receiver device, wherein the first network device receives a message from a multicast tracing client to trace a multicast path from the receiver device to the source device; generating a second multicast trace request based on the format for the core network using information from the first multicast trace request; and transmitting the second multicast trace request from an edge network device to the receiver device using the core network, the second multicast trace request including network information related to network performance between the first network device and the edge network device

    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.
