PACKET COMMUNICATION NETWORK AND PACKET COMMUNICATION METHOD

摘要

Each of packets is received from an external network (U1) by a distributing means (2) that is connected to a parallel network (1) comprising a plurality of physically or logically independent networks (N1-Nm). The received packet is then distributed by the distributing means (2) into any one of the networ ks (N1-Nm) in the parallel network (1). The packets as forwarded by the network s (N1-Nm) in the parallel network (1) are then multiplexed by a multiplexing means (3) also connected to the parallel network (1), and then outputted to an external network (U2). In this way, a packet forwarding related to a particular service between the external networks (U1,U2) can be executed without being affected by the traffics of other services.
