Abstract
Official abstract text for this publication.
A network relay system includes a plurality of communication devices. Each of the communication devices includes a data plane that transfers an input packet according to routing information, and a control plane having a processing unit that learns the routing information, and a control system repeater. The data planes of the respective communication devices can realize a non-blocking communication therebetween. Also, the control system repeater of an operational system receives the routing information from the processing unit, sets the routing information for the data plane of the subject communication device, and transmits the routing information to the control system repeater of the other communication device. The control system repeater of a standby system receives the routing information, and sets the routing information for the data plane of the subject communication device.
