Network System, Edge Node, and Relay Node

摘要

Edge nodes form point-to-point communication paths with one another. Multiple communication paths set at one port of an edge node and/or a relay node are regarded as a group. Identification information of the port and identification information of a group that outputs a frame inputted into the port are previously stored as associated with each other. If the destination address of a frame inputted into the port is unknown, an outgoing interface search unit identifies at least one group corresponding to the port. The frame is outputted from a port corresponding to the identified group.
