摘要： PROBLEM TO BE SOLVED: To protect ALL frames and to prevent the loss of packets by referring to the PT field of ATM cells during transfer at present and waiting for the execution of changeover until the boundary of frames is recognized in switching a virtual transfer line. SOLUTION: A virtual transfer line change request G2 arrives after a cell C1 has been processed, however, as indicated by a change waiting period W1, the changeover of the virtual transfer line is waited for until the cell positioned at the boundary of the frames, that is the cell Cn for which the value of the PT field is 1, arrives. Thus, no packet is lost in communication from a node 1A to the node 1B and the communication 18 normally performed. Then, once judged that the setting change of a switch is required, a packet processing part 21 sends out the virtual transfer line change request to a switch part 24. A switch control part inside the switch part 24 receives it, converts it to an interface control instruction and transfers it.

摘要： PROBLEM TO BE SOLVED: To provide a packet transfer device which is capable of moving a terminal from one segment to the other without changing a terminal IP address and to provide a packet communication network. SOLUTION: The packet transfer device forms an internal sub-network with a set of broadcast segments holding terminals. When the packet transfer device receives a MAC frame specifying the terminal of the other segment at a destination IP address from a terminal connected to one of the segments in the internal sub-network, it transfers IP packets in the MAC frames to the connected segments of the destination terminals in accordance with a terminal control table indicating a corresponding relation between the address information of the terminals belonging to the internal sub-networks and the connection segments.

摘要： PROBLEM TO BE SOLVED: To provide a router that can cope with communications in diversified forms by enhancing the multiplicity of communications conducted via an ATM switch so as to reduce dispersion in communication delays among multiplexed communications. SOLUTION: The router 5 is provided with the ATM switch 52, an IP control section 53 that conducts routing control, a plurality of kinds of interface sections 512-517 provided individually for a plurality of transmission lines for diversified communications, and a cell multiplexer/demultiplexer section 511, and the router 5 manages communication of cells among the sections above by identification information. The interface section 512 applies IP processing to IP packets received from an IP node 41 and assembles them into cells of a common form. Then the cell multiplexer/demultiplexer section 511 applies serial multiplexing to the cells to multiplex them with cells from other interface sections in the unit of cells and the multiplexed cells are fed to the ATM switch 52. Each interface section and the cell multiplexer/demultiplexer section 511 have a table on which correspondence relation of the identification information is registered and the table is used to set the identification information to each header part of communicated IP packets and cells with/ without conversion.

摘要： PROBLEM TO BE SOLVED: To prevent the omission of packet caused by the change of virtual transfer route by reducing the processing load of the switch part by decreasing the number of times to change the virtual transfer route. SOLUTION: Even when it is judged that a virtual use transfer route change request is to be outputted by a packet processing part inside a present node, an exchange node 2 does not immediately sends out a new virtual transfer route change request to a switch part 24 but waits for the arrival of the virtual use transfer route change request from a node 18B at the transfer destination of data packet for a fixed time. When the change request arrives, the setting request of the new virtual transfer route for connecting a node 1A at the transfer source of data packet and the node 1B without through a protocol processing part 213 is sent out to the switch part 24.

摘要： PROBLEM TO BE SOLVED: To perform application even outside a range of a standard sequence using PMIPv6 for an I/F between S-GW and P-GW without adding a function to a policy server and without raising loads.SOLUTION: The policy server transmits an additional bearer setting request for associating a communication path of a first terminal and a communication path of a second terminal to a mobility anchor. In the case of receiving the additional bearer setting request, the mobility anchor determines the propriety of setting a fifth communication path connecting a first communication path and a third communication path, records information related to the fifth communication path about the propriety of setting the fifth communication path in communication path management information, and transmits a link preparation request including the communication path management information to an access gateway device. The access gateway device transmits data transmitted from the first terminal through the first communication path to the second terminal through the fifth communication path and the third communication path.
