IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is the IP-specific form of multicast and is used for streaming media and other network applications.
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 .
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model ), such as Ethernet multicast, and at the internet layer (layer 3 for OSI ...
The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IPv4 networks to establish multicast group memberships. IGMP is an integral part of IP multicast and allows the network to direct multicast transmissions only to hosts that have requested them.
[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.).
Example of a multicast network architecture. Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet.
The successor to IPv4, IPv6 does not implement the broadcast method, so as to prevent disturbing all nodes in a network when only a few may be interested in a particular service. Instead, IPv6 relies on multicast addressing - a conceptually similar one-to-many routing methodology. However, multicasting limits the pool of receivers to those that ...
It was designed to work as either a stand-alone protocol or compatible with standard DNS servers. [1] It uses IP multicast User Datagram Protocol (UDP) packets and is implemented by the Apple Bonjour and open-source Avahi software packages, included in most Linux distributions.
