Network system for transmitting a plurality of channels, and node device, packet transmission method, terminal equipment connection table generation method, and connection information registration method used in the system

摘要

A source terminal equipment connected to a node device transmits a packet by appending a section for designating the channel to be used upon relaying the packet by the node device to the packet. The relaying node device determines the channel used upon outputting the packet by looking up the value in the section for designation of the channel. The source terminal equipment transmits the packet by appending relaying number information indicating the number of relayings of the packet to the packet. Each node device looks up the relaying number information upon looking up the value in the section for designation of the channel. When each node device outputs a packet to a terminal equipment using a separation device for separating the packet toward the sub transmission path side, the node devices determines, based on the relaying number information, whether or not it separates the packet. This invention also discloses a method of generating a terminal equipment connection table and a method of registering connection information using the above-mentioned transmission method.
