Node, network, creating method of corresponding relation for transmitting information in network

A node, a network, a correspondence creating method and a frame transferring program for achieving, in EoE technique, an optimum path transfer, thereby avoiding the traffic concentration to any particular link so as to improve the throughput of the whole network. A frame switching part comprises a frame analyzing part for analyzing the input frame type or the like; a table search part for acquiring frame rewriting information and output port information; a forwarding table storing part for managing a frame output port; a MAC learning part for performing a MAC address learning; an EoE-MAC learning part for learning a relationship between a MAC address and a EoE-MAC address; an STP control part for performing a spanning tree process; and so on.
