Abstract
In a method and a device for virtual concatenation transmission which multiplex traffics of low-speed frames into a high-speed frame based on a virtual concatenation, a virtual concatenation with an excellent transmission efficiency is provided. Specifically, in order to provide the transmission method and the device which do not waste channels, require little labor of operators, do not cause an instantaneous interruption, and require no memory capacity, a plurality of low-speed frames are multiplexed into arbitrary positions within a high-speed frame to compose a virtual concatenation, and are transmitted together with virtual concatenation information indicating a concatenation state of positions of the low-speed frames, with a phase relationship being maintained.
