Network interconnection apparatus network node apparatus and packet transfer method for high speed large capacity inter-network communication

摘要

At a time of transmitting a packet from a node connected with one logical network to another logical network, a control message is transmitted to a network interconnection apparatus connecting the one logical network and the another logical network, when a new node is activated beyond the network interconnection apparatus, the control message including information for a registration in the network interconnection apparatus of a correspondence relationship between a first virtual path to be used in receiving a packet from the one logical network and a second virtual path to be used in transmitting the packet to the another logical network.
