  2. Broadcast, unknown-unicast and multicast traffic - Wikipedia

    en.wikipedia.org/wiki/Broadcast,_unknown-unicast...

    Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs. When a VTEP comes alive it uses the Internet Group Management Protocol to join the multicast groups for the VNIs it uses. When a VTEP has to send BUM traffic it will send ...

  3. Xcast - Wikipedia

    en.wikipedia.org/wiki/Xcast

    The explicit multi-unicast (Xcast) is a variation of multicast that supports a great number of multicast sessions with a small number of recipients in each. It adds all the destination IP addresses in the IP header, instead of using a multicast address.

  4. Multiprotocol BGP - Wikipedia

    en.wikipedia.org/wiki/Multiprotocol_BGP

    Multiprotocol Extensions for BGP (MBGP or MP-BGP), sometimes referred to as Multiprotocol BGP or Multicast BGP and defined in IETF RFC 4760, [1] is an extension to Border Gateway Protocol (BGP) that allows different types of addresses (known as address families) to be distributed in parallel.

  5. Broadcasting (networking) - Wikipedia

    en.wikipedia.org/wiki/Broadcasting_(networking)

    In computer networking, telecommunication and information theory, broadcasting is a method of transferring a message to all recipients simultaneously. Broadcasting can be performed as a high-level operation in a program, for example, broadcasting in Message Passing Interface, or it may be a low-level networking operation, for example broadcasting on Ethernet.

  6. Unicast - Wikipedia

    en.wikipedia.org/wiki/Unicast

    In computer networking, unicast is a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. [ 1 ] Unicast is in contrast to multicast and broadcast which are one-to-many transmissions.

  7. Multicast address - Wikipedia

    en.wikipedia.org/wiki/Multicast_address

    Multicast address scope IPv6 address [note 1] IPv4 equivalent [19]: §8 Scope [28] Purpose ffx0::/16, ffxf::/16: Reserved ffx1::/16: Interface-local Packets with this destination address may not be sent over any network link, but must remain within the current node; this is the multicast equivalent of the unicast loopback address. ffx2::/16: ...

  8. Multicast routing - Wikipedia

    en.wikipedia.org/wiki/Multicast_routing

    [2] [3] [4] Regarding IP multicast, it is a technique for one-to-many communication over an IP network. IP multicast covers some part of common multicast routing protocol. IP multicast also describe IP multicast software (i.e. VideoLAN,qpimd – PIM Daemon for Quagga, GNU — PIM module for the Quagga Routing Suite, UFTP, etc.).

  9. Reverse-path forwarding - Wikipedia

    en.wikipedia.org/wiki/Reverse-path_forwarding

    It does this by utilizing either a dedicated multicast routing table or, alternatively, the router's unicast routing table. When a multicast packet enters a router's interface, the router looks up the list of networks that are reachable via that interface (i.e., it checks the paths by which the packet could have arrived).
