    Abstract: Various systems and methods for performing bit indexed explicit replication (BIER) using IPv6. For example, one method involves receiving, at a node, a packet that includes an IP header. The packet also includes a multicast forwarding entry. The method also involves comparing the multicast forwarding entry with forwarding information stored by the node and selecting a neighbor based on the comparing. The method further includes forwarding the packet to the neighbor.

    Abstract: A method and network device are disclosed for multicast forwarding. In one embodiment, the method includes receiving at a node configured to use a bit-indexed forwarding table a multicast message comprising an incoming message bit array. The method further includes comparing the incoming message bit array to a first neighbor bit array within a first forwarding table entry, and determining that for at least one relative bit position in the bit arrays a corresponding destination node is both a destination for the message and a reachable destination from a first neighboring node. The method further includes forwarding toward the first neighboring node a copy of the message, where a first node on the path of the forwarded message is not configured to use a respective bit-indexed forwarding table. An embodiment of the device includes a network interface, a memory and a processor configured to perform steps of the method.

    Abstract: Computer systems and methods for improving a computer's ability to interface with a user to configure one or more internetworking services provided by a first group of computers for a second group of computers using a pictorial graph with nodes that represent logical network objects. In an embodiment, a computer system comprises: a display; a memory persistently storing a set of instructions and a set of data that defines a plurality of logical network objects; one or more processors coupled to the memory and the display, wherein the one or more processors execute the set of instructions, which causes the one or more processors to: retrieve, from the memory, the set of data that defines a plurality of logical network objects, wherein a first logical network object represents a particular internetworking service that is provided by one or more first computing devices among the plurality of computing devices in the computer network, and a second logical network object represents a corresponding grouping of one or more second computing devices of the plurality of computing devices in the computer network; cause to present, on the display, a plurality of nodes in a first pictorial graph, wherein each node in the plurality of nodes corresponds respectively to each object in the plurality of logical network objects.

    Abstract: Methods and network devices are disclosed for multicast forwarding. In one embodiment, a method includes receiving at a node a multicast message comprising a message header, where the message header comprises an incoming message bit array and a set identifier value associated with the incoming message bit array. The method further comprises selecting a first forwarding table entry, the first forwarding table entry comprises a set identifier value matching that of the message header. The method further comprises comparing at least a portion of the incoming message bit array to a corresponding portion of a neighbor bit array of the first forwarding table entry, determining that for at least one relative bit position a corresponding destination node is both a destination for the message and a reachable destination from a first neighboring node, and forwarding a copy of the message to the first neighboring node.
