<p>A node apparatus wherein when the connection is multiplexed, the implementation and operation of filters and IPsec SPD and so on can be readily performed and the problem of port information can be solved. The multiplexing of sessions to be provided to the application layers in a transport layer (120) and a network layer (130) is integrated into the multiplexing process (131) in the network layer (130). Port equivalent information is put into an IP address, thereby unifying the resolving, so that no well-known port number must be used. Additionally, when the sessions are multiplexed in the multiplexing process (131), only the IP address is handled.</p> |
