In Multicast routing protocol transmission method one device communicates with several devices in a single transmission.A multicast address is a single IP data packet set that represents a network host group. Multicast addresses are available to process datagram’s or frames intended.
Different Ranges of multicast address:
Multicast address ranges from the 188.8.131.52 to 184.108.40.206. IPV4-reserved address for multicast
- 220.127.116.11: based address reserved
- 18.104.22.168: Used for all multicasting host groups
- 22.214.171.124: Used for all subnet routers
- 126.96.36.199 and 188.8.131.52: Used by Open Shortest Path First, an interior gateway protocol for all network segment routing information.
Procedures involved in setting multicast network:
- Routers in the network’s are multicast enabled
- Configurations of multicast network is also support multicast enabled.
- Select the address you’ll use for your multicast
Algorithm involved in multicast routing protocol:
- Reverse path multicasting.
- Core-based tree.
- Spanning trees.
- Truncated reverse path broadcasting.
- Reverse path broadcasting etc.
Many different algorithm can be implemented for multicast routing protocol projects depending upon requirement of your projects.,
