    摘要: A header compression/decompression apparatus that improves the throughput of an overall multilayer protocol stack at a network node. In this apparatus, an encoding section 106 compresses multilayer header information included in a protocol data unit on a multilayer protocol stack 101. A session context ID manager 112 generates a session context ID 401 which is formed by integrating information on compression of multilayer header information by the encoding section 106 and, for example, information for identifying a scheme for compressing multilayer header information.

    摘要: As an apparatus itself moves, its access section 101 gets access to router AR2 using a temporarily assigned global address when making a roaming connection to a different network from a network to which the apparatus belongs currently. Message generating section 102 generates a Binding Update message, which contains a global address which is uniquely assigned to network element apparatus 100, the above temporarily assigned global address, and a global address of the router AR1, to transmit the generated message via the access section 101 to router AR2, which is a serving router after move. This makes it possible to deliver packets among moving networks with the minimum delay to an intended recipient.

    摘要: An access control method for a plurality of data communications networks is disclosed that enables a plurality of local nodes (101) to communicate with each other even if the connection between an intermediate node (103) and a global server (105) is momentarily lost. In this method, when the connection to the global server (105) breaks down, the intermediate node (103) temporarily grants access to the local nodes (101) instead of the global server (105) in accordance with a predetermined policy, thus allowing operation of local networks to function normally until connection to the global network (104) is resumed.

    摘要: A mobile network control apparatus capable of improving transmission efficiency without giving any processing loads to nodes of a mobile network. In mobile routers to which the present apparatus is applied, a tunnel failure detection unit detects a failure of packet tunneling executed using an interface of the mobile routers. A multi-homing detection unit searches for interfaces having a connection route to a global network out of an interface of the mobile routers according to the detected failure of packet tunneling. A bidirectional tunneling unit executes packet tunneling using the searched interfaces instead of the interface of the mobile routers.

    摘要: A mobile network control apparatus capable of improving transmission efficiency without giving any processing loads to nodes of a mobile network. In mobile routers 121, 131, 132 to which the present apparatus is applied, a tunnel failure detection unit 204 detects a failure of packet tunneling executed using an interface 205-1 of the mobile routers 121, 131, 132. A multi-homing detection unit 202 searches for interfaces 205-A, 205-B having a connection route to a global network 101 out of an interface 205 of the mobile routers 121, 131, 132 according to the detected failure of packet tunneling. A bidirectional tunneling unit 203 executes packet tunneling using the searched interfaces 205-A, 205-B instead of the interface 205-1.
