Method for implementation of a full-duplex switched Ethernet redundant communication network

摘要

The Ethernet communication network comprises at least two independent elementary networks (RE1, RE2) linking source and destination subscriber equipment. Frame by frame redundancy is provided on the elementary networks, by the use of a numbering field added to each transmitted frame. ??The full-duplex switched Ethernet communication network with redundancy comprises at least two independent elementary networks (RE1, RE2). Each network includes source subscriber equipment and destination subscriber equipment linked together via a switching network. Frame by frame redundancy is provided on the elementary networks. A numbering field is added to each transmitted frame, enabling the insertion of a frame number, and this is transmitted via both networks. The frame numbers are memorised at reception, and the frame is taken into account if its number has not already been received. The acceptance of a frame takes place within a determined time window.
