<p>PROBLEM TO BE SOLVED: To improve transfer efficiency by storing the relation of correspondence between the identifier of virtual connection and a connection interface to be the transfer destination and deciding the connection interface to be the transfer destination of datagram on the identifier of the virtual connection of datagram. SOLUTION: Assuming that virtual connection 1, 2 and 10 are set to an I/F 1, virtual connection 3 is set to an I/F 2 and a transfer table 1201 of a connection (CN) identifier analytic part 121 of the I/F and a path length 2101 of a datagram (DG) analytic part 211 are set, when the DG flows to the virtual CN 1, a reception part 111 , dispatches the DG and its CN identifier to the analytic part 121 . The analytic part 121 decides the CN 3 of the I/F 2 as the output destination of that DG while referring to the transfer table 1201 with the CN 1 as a key. Then, the DG and the CN 3 are dispatched through a transfer part 30 to a DG processing part 222 and after network layer processing is executed, they are transmitted through a transmission part 132 to the CN 3.</p> |
