Node, network, correspondence creating method, and frame transferring program

Providing the nodes in the network EoE art, correspondence relation generating method, and frame transmission procedures, to avoid the traffic concentration on a specific link in order to improve overall network throughput optimal paths. The frame comprises a switching unit for analyzing the kind of input frame of frame analysis unit for obtaining information of a frame rewriting the table search unit and the output port information, means for storing the output port forwarding management frame for performing MAC address EoE-MAC learned MAC unit is informed, to learn the relationship between the MAC address and the address informed EoE-MAC unit, the control unit for processing executed STP spanning tree, and the like.
