Aiming at the problem of manual selection of Area Border Router(ABR) can not satisfy the dynamic change in the network load in Open Shortest Path First(OSPF) protocol.This paper proposes a new algorithm of the dynamic appointment of ABR for OSPF.Based on observed traffic demands and knowledge on link capacities,the proposed algorithm locates an adequate ABR for the new traffic pattern to avoid incipient link congestion and accompanying performance degradation.NS2 simulation results show that the proposed algorithm gets a better performance at parameters such as end-to-end delay and packet loss rate.
