<p><P>PROBLEM TO BE SOLVED: To provide a communication system for resetting a terminal and updating routing information immediately after a router is initialized to resume. <P>SOLUTION: When an RACS (resource and admission control subsystem) function 4 monitors a failure of an SSE (subscriber service edge) 5 for routing, and detects initialization resume of the SSE 5, an NASS (network attach subsystem) function 2 requests resetting of the information including an IP address to user terminals 61, 62 to be influenced, and updates or redelivers the IP address, in response to the update request from each of the user terminals 61, 62. In this way, the SSE 5 detects that the IP address information is updated by DHCP (dynamic host configuration protocol) from communication between the NASS function 2 and the user terminals 61, 62, to update the routing information. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
