Abstract

The invention discloses an IP data backup transmission method independent of a routing protocol or algorithm. A wireless channel (an ad-hoc wireless ad hoc network, a wifi network, etc.) is used as abackup transmission channel, and a layer two switching function of a three-layer switching network chip is used to achieve the purpose of reliable transmission assisted with a wired channel to transmit the IP data. Through the IP data backup transmission method independent of the routing protocol or algorithm, an IP three-layer switching network can be deployed within a reaching range of one hop of the wireless channel, so that the backup transmission can be carried out on the IP data through the wireless channel, and the purpose of reliable transmission is achieved; and when a wired channel route changes, the IP data transmission of the wireless channel is not affected; therefore, it can be ensured that the reachability of the IP data can be independent of the path specified by the routing protocol. The wired channel and the wireless channel are mutually backup relationships; therefore, the reliability of the entire IP data transmission system is improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, and more specifically relates to an IP data backup transmission method independent of routing protocols or algorithms. Background technique [0002] The transmission mode of the IP transmission network is best-effort hop-by-hop forwarding, and IP transmission cannot guarantee that data can reach the destination. The reliable transmission of IP data is generally realized by establishing a TCP connection between data terminals, and the reliable transmission of UDP services (including real-time data streams such as video and voice) generally relies on three types of technologies: [0003] Port backup: related technologies are MSTP equipment (multi-service transmission equipment) and port multiplexing. There are two paths between MSTP devices, the working optical fiber and the standby optical fiber. Under normal circumstances, the working optical fiber transmits business data. The network ...
