<p>PROBLEM TO BE SOLVED: To exchange a packet group received after transfer of a 1st packet among packet streams with same header information by selecting a path other than a path through which the 1st packet is transferred. SOLUTION: Upon the receipt of a packet being an object of logic channel changeover by an IP-CONT 63, a logic channel changeover function section 611 of an Edge 61 exchanges mutual information with a logic channel changeover function section 632 of the IP-CONT 63 to generate other path 12. Then the logic channel changeover function section 632 of the IP-CONT 63 informs a path changeover section 64 of production of the path 12, and a switch changeover function section 641 of the path changeover section 64 operates an ATM-SW 62 based on a judgment to connect paths 12, 14.</p> |
