<p>Managing network information in Access Routers(ARs) includes: communicating with neighbouring Access Routers (ARs) to obtain information of each of the ARs and Access Points (APs) belonging to a subnet of a relevant AR; storing the information of the ARs and APs in a database; and performing a communication network service in accordance with the information stored in the database. Desired information can be shared without a need for adding any separate element to the network architecture. In addition, because a Candidate Access Router (CAR) table is generated during the operation of the Open Shortest Path First (OSPF), the AR immediately responds to the information requested by a mobile node so as not to increase a handoff delay and so as to reduce a burden of the mobile node. <IMAGE></p> |
