Problems solved by technology

[0005] The formulation of the above protocol can basically guarantee the quality control of the multicast source data flow during transmission, but the long-term stable operation of the multicast source is a more important prerequisite for ensuring the quality of multicast services. figure 1 What is shown is the traditional multicast source configuration method. The multicast source server 100 is directly connected to the multicast router 101. Under the influence of viruses or software defects, system problems caused by long-time work may cause multicast The instability of the source will cause the sudden interruption of the multicast service in serious cases, causing the problem that the user cannot receive the multicast data

Embodiment Construction

[0044] The present invention mainly sets multicast source main server, multicast source standby server and a multicast proxy server, and runs multicast source main and standby control between the multicast source main server, multicast source standby server and multicast proxy server. Protocol, so that the multicast source server can run stably under any circumstances.

[0045] Below in conjunction with accompanying drawing, the multicast source active-standby switching system that makes multicast source server stable operation of the present invention is described in further detail: as figure 2 As shown, the active-standby switchover system of multicast source of the present invention is made up of a multicast source master server, a multicast source backup server dual multicast source and a proxy server, and the multicast source system 100 in the figure corresponds to figure 1 The multicast source servers 100, 201 and 202 are two multicast source servers with the same funct...

Abstract

The invention discloses a master / slave switching system for multicast source, and a method thereof, which relate to multicasting transmission protection technology and are invented in order to solve a problem that the multicast source is not stable in the prior art. The invention comprises a multicast source server and a multicast agent server; and the multicast source server comprises a master server for multicast source and a standby server for multicast source. The multicast agent server is respectively connected with the multicast source server and the standby server for multicast source and is used for internally providing the master server for multicast source and the standby server for multicast source with cooperative interfaces and externally converting data stream source addresses of the master server for multicast source and of the standby server for multicast source into the same pubic IP address and forwarding the multicast source data stream. Through dual CPU hot-redundancy, the invention ensures multicast source data stream program is not interrupted and enhances stability of the multicast source and service quality of the multicasting program.

Description

technical field [0001] The invention relates to a protection technology for multicast transmission, in particular to a system and method for multicast source active / standby switching. Background technique [0002] Multicast technology is a technology that can realize point-to-multipoint or multipoint-to-multipoint communication. The basic characteristics of multicast technology are described in RFC1112. Multicast technology can be used to conveniently transfer multimedia audio and video data from For the transmission from the server to multiple clients, no matter how many clients there are, the server only needs to send it once. It can be seen that the multicast technology can not only save network resources, but also reduce the workload of the server. [0003] The group in multicast technology is a logical concept, not a fixed physical entity group. Any terminal that can access network resources can join the multicast group without being restricted by its own physical locat...
