摘要： A method and apparatus for exchanging routing information in a distributed router system provide enhanced reliability of routing information exchanged between routing processors. To exchange routing information between routing processors in a distributed router system, a transceiving unit adds a header, including a sequence number, to update information transmitted from the routing protocol daemon, and multicasts the update information to another peer. A control unit transmits a sequential update packet, provided by a peer, to the transceiving unit, and a continuous update packet is stored in a receiver buffer for the routing protocol daemon. The control unit then stores in the receiver buffer a non-sequential update packet provided by another peer to the transceiving unit, in the receiver buffer, receives a synchronous signal from another peer, and releases the sender buffer. Subsequently, the control unit receives a maximum value, requests the retransmission of a lost packet, and transmits the maximum value and the synchronous signal periodically. Finally, if a retransmission request signal is received from another peer through the transceiving unit, the lost packet is read from the sender buffer, and is retransmitted through the transceiving unit.

摘要： A routing table management method using an interface ID in the IPv6 that supports RIPng (Routing Information Protocol for next generation), prevents congestion in routing table management because multiple addresses are designated to a single interface, through managing a routing table using a different interface ID for each IPv6 router interface. According to the routing table management method, a first router designates a predetermined value to a first field of a route entry, designates an interface ID to a second field, thereby generating routing information, and a routing information packet including the routing information is transmitted to a second router. Then, the second router extracts a first field value of the received routing information packet from the first router and if the extracted field value is a predetermined value, a second field value is extracted therefrom. Lastly, routing information of a route entry having an interface ID identical with the extracted second field value is updated to routing information of the received routing information packet.

摘要： Managing network information in Access Routers (ARs) includes: communicating with neighboring 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.
