NETWORK RELAY SYSTEM AND NETWORK RELAY DEVICE

摘要

Simplification of control and prevention of a setting performance from being deterioration are realized while showing a local side data plane and a remote side data plane in the same fashion when viewed from a control plane. A network relay system includes a plurality of communication devices 1000. Each of the communication devices includes a data plane 20 that transfers an input packet according to routing information, and a control plane 1100 having a processing unit 1110 that learns the routing information, and a control system repeater 1120. The data planes 20 of the respective communication devices can realize a non-blocking communication therebetween. Also, the control system repeater 1120 of an operational system receives the routing information from the processing unit 1110, sets the routing information for the data plane 20 of the subject communication device, and transmits the routing information to the control system repeater 1120 of the other communication device 1100-2. The control system repeater 1120 of a standby system receives the routing information, and sets the routing information for the data plane 20 of the subject communication device.
