Multicast Routing is one of the routing protocols in TCP/IP communication. [1]
In computer networking, there are several multicast group communication protocols where data transmission is addressed to a group of destination computers simultaneously. [2]
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. [2] 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 multicast transmission.[2]
Routing mechanism
A multicast routing protocol is a mechanism for constructing a loop-free shortest path from a source host that sends data to the multiple destinations that receives the data. IPV4 uses Class D address (224.0.0.0 ~ 239.255.255.255) [2]
