Multicast Routing
Multicast routing is one of the routing protocols in IP networking. CISCO Security Research & Operations- 3 June 201Understanding Unicast Reverse Path Forwarding , Cisco -unicast-reverse-path-forwarding/ref> There are several multicast routing protocols supporting communications where data transmission is addressed to a group of destination computers simultaneously: Multicast Source Discovery Protocol, Multicast BGP, Protocol Independent Multicast. Overview Multicast routing is a method of transmitting to all subscribers registered in a group by one transmission unlike unicast routing (i.e. OSPF, RIP) which transmits 1: 1 necessary data. CISCO Security Research & Operations- 3 June 201IP Multicast Routing Technology Overview , Cisco IP Multicast Routing Technology Overview/ref> To implement the multicast routing, IGMP protocol and multicast routing protocol (Reverse-path forwarding, PIM-SM) for registration subscriber grouping and control traffic are required for mul ...

Multicast
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication. Group communication may either be application layer multicast or network-assisted multicast, where the latter makes it possible for the source to efficiently send to the group in a single transmission. Copies are automatically created in other network elements, such as routers, switches and cellular network base stations, but only to network segments that currently contain members of the group. Network assisted multicast may be implemented at the data link layer using one-to-many addressing and switching such as Ethernet multicast addressing, Asynchronous Transfer Mode (ATM), point-to-multipoint virtual circuits (P2MP) or InfiniBand multicast. Network-assisted multicast may also be impl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
