It is determined whether or not the address of a first type specified in an address resolution query is an address that allows direct routing to a first network. If the direct routing is determined to be allowed, a routing table is configured such that a packet including, as a destination, the address of a second type obtained by the address resolution query is forwarded to the first network. If the direct routing is determined not to be allowed, the routing table is configured such that a packet including the obtained address of the second type as a destination is forwarded to a second network.

Routing method and network transmission apparatus

An access control method for a network including a plurality of packet communication apparatuses is disclosed. The access control method includes a first step in which a sender packet communication apparatus attaches user attribute information to a packet to be transmitted, and a second step in which a communication control mechanism within an end system corresponding to a destination packet communication apparatus or a packet receiving apparatus performs access control based on the user attribute information attached to the packet.

Access control method, access control system, and packet communication apparatus

In an access management method in a network including at least one end system, a packet communication unit for routing, and an access management server including an authentication function, a communication partner is authenticated for each session and a communication permitted by a communication partner is permitted by the access management server. A packet meeting a condition of a denied packet being denied by the communication partner is discarded by the packet communication unit.
