Abstract

The invention relates to the technical field of communication, in particular to a message transmission system and method supporting unicast and broadcast, and the system comprises an intermediate forwarding module which comprises a first judgment module, a second judgment module, a third judgment module and a fourth judgment module. The first judgment module is used for judging whether the data packet meets the specification or not, calling the data sending module if the data packet meets the specification, and calling the return module if the data packet does not meet the specification; the second judgment module is used for judging whether the data packet conforming to the specification is a forwarding message or not, the third judgment module is used for judging whether a sending source of the data packet conforming to the specification and being the forwarding message exists or not, and the fourth judgment module judges the forwarding type of the data packet according to the forwarding parameter. According to the method, information congestion of an information transmission channel and congestion of a backbone network can be avoided, accumulation of a large amount of useless information on a host of an application program is reduced, and memory occupation is reduced.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a message transmission system and transmission method supporting unicast and broadcast. Background technique [0002] There are three transmission modes of TCP / IP: unicast, broadcast, and multicast. Unicast transmission: requires a separate data channel between the sender and each receiver. If a host transmits data to a small number of receivers at the same time, there is generally no problem. But it is difficult to achieve if a large number of hosts want to get the same copy of the data packet. This will lead to heavy burden on the sender, long delay, and network congestion; in order to ensure a certain quality of service, hardware and bandwidth need to be increased. Multicast (Multicast) transmission: It improves the efficiency of data transmission. The possibility of congestion on the backbone network is reduced. The hosts in the multicast group can be in...
