  2. Multicast - Wikipedia

    en.wikipedia.org/wiki/Multicast

    In IP multicast the implementation of the multicast concept occurs at the IP routing level, where routers create optimal distribution paths for datagrams sent to a multicast destination address. Multicast is often employed in Internet Protocol (IP) applications of streaming media , such as IPTV and multipoint videoconferencing .

    Broadcast traffic is reduced and VXLAN tunnel endpoints (VTEPs) reply to the caller directly. VXLAN can handle BUM in two ways: Multicast and Head End Replication. 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.

  4. IP multicast - Wikipedia

    en.wikipedia.org/wiki/IP_multicast

    Broadcast packets make use of the broadcast MAC address FF:FF:FF:FF:FF:FF. IPv4 multicast packets are delivered using the Ethernet MAC address range 01:00:5E:00:00:00 through 01:00:5E:7F:FF:FF (with an OUI owned by the IANA). This range has 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit.

  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. Broadcast address - Wikipedia

    en.wikipedia.org/wiki/Broadcast_address

    A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts. In contrast, a multicast address is used to address a specific group of devices, and a unicast address is used to address a single ...

  7. 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.

  8. Packet forwarding - Wikipedia

    en.wikipedia.org/wiki/Packet_forwarding

    For example, fiber optics and copper cables run directly from one machine to another to form a natural unicast media – data transmitted at one end is received by only one machine at the other end. However, as illustrated in the diagrams, nodes can forward packets to create multicast or broadcast distributions from naturally unicast media.

    LTE's Enhanced Multimedia Broadcast Multicast Services (E-MBMS) provides transport features for sending the same content information to all the users in a cell or to a given set of users (subscribers) in a cell using a subset of the available radio resources with the remaining available to support transmissions towards a particular user (so-called unicast services).
