Methods of data transmission by relay nodes in a synchronous communications network, corresponding reception method, computer program product, storage means and nodes.

摘要

A method for the transmission of data in a synchronous communications network comprising a plurality of nodes, a super frame being communicated based on a network cycle on the network and comprising a plurality of frames, each frame being associated with one of the nodes. Each frame comprises a payload part itself comprising an own data section and a repeat data section. The plurality of nodes comprises at least one relay node associated with an application generating own data of the relay node having to be transmitted to at least one second node. The relay node performs the following steps: reception (204) of frames coming from the other nodes; reading (208) of a predetermined part of the data from the received frames, enabling repeat data to be obtained; writing (208) said repeat data in the repeat data section of a new frame; writing (207) own data of said relay node in the own data section of the new frame; and transmission (209) of the new frame.
