<p>In a known 1:1 redundant communication method, if traffic passes through a working communication path, there is no traffic in a backup communication path other than a switching control packet for instructing control of switching between the working communication path and the backup communication path. This is a problem for the efficiency of the communication bandwidth of the backup communication path. In a 1:1 redundant communication system, the present invention enables flexible communication in the backup communication path and the effective use of communication bandwidth of the backup communication path by controlling traffic in the backup communication path on the basis of information on the condition of the working communication path included in the switching control packet that is transmitted via the backup communication path.</p> |
