5.1 Overview
With the continuous development of Internet network, the various interacting network data,
voice and video will become more and more; the other hand, the emerging e-commerce,
online meetings, online auctions, video on demand, distance learning and other services also
rise gradually. These services come up with higher requirements for network bandwidth,
information security and paid. Traditional unicast and broadcast cannot meet these
requirements well, while multicast has met them timely.
Multicast is a point to multipoint data transmission method. The method can effectively solve
the single point sending and multipoint receiving problems. During the network packet
transmission, it can save network resources and improve information security.
Basic concept in multicast
Multicast group
Multicast group refers to the recipient set using the same IP multicast address identification.
Any user host (or other receiving device) will become a member of the group after joining the
multicast group. They can identify and receive multicast data with the destination address of
IP multicast address.
