Multicast is a kind of allowing one or more of the sender to send a single data to multiple recipients of network technology, no matter how much the number of group members, the data source only to send a packet, and multicast only to those who need to send a packet of host and network package (in the multicast address addressing), in the IP multicast group members is the relationship between dynamic, multicast receiving host may at any time to join or leave the multicast group, in addition, multicast receiving host can be any number of members of a multicast group, on the Shared links, the same information need only a multicast stream, which can effectively control flow, reduce the burden of the host and network, improve the efficiency and ability of network application service [1],CodePudding user response:
All of the IP is sent to the same routerCodePudding user response:
Baotou first byte is an odd number of multicast packets, so all the same physical network segment of the network equipment will receive the package, the protocol stack of equipment will figure out whether 224.0.0.88 for yourself, if it is to continue processing, not release package lost memory,CodePudding user response:
Multicast address 224.0.0.88 sends data, the data will be sent to all hosts in the networkYou need to understand that program will receive a multicast address data, need to add your own socket to the multicast address to receive others to the multicast address data
CodePudding user response:
Is only sent to the IP for 224.0.0.88, routing will handle, and then if the host has been added to the multicast routing is to forward the data to the host addressCodePudding user response:
