Chapter 8 Multicast ¾ Multicast Overview In the network, packet s are sent in three modes: unicast, broadcas t and multicast. In unicast, the source server sends separate copy information to each receiver . When a large number of users require this information, the serv er must send many pieces of info rmation with the same content to the users.
1. Multicast IP Address: As specified by IANA (Internet Assigned Numbers Authority), Class D IP addresses are used as destination addresses of multic ast packets. The multicast IP addresses range from 224.0.0.0~239.255.255.255. The following table displays the range and description of several special multicast IP addresses.
¾ IGMP Snooping In the network, the hosts apply to the near Router for joining (leaving) a multicast group by sending IGMP (Internet Group Management Protocol) me ssages. When the up-str eam device forwards down the multicast data, the switch is responsible for sending them to the hosts.
The host, running IGMPv1, does not send IGMP l eave message when leaving a multicast group, as a result, the switch can not get the leave information of the host momentarily .
