Traffic Optimization on the Dynamic Switching of ABR for OSPF Networks

Abstract

Open Shortest Path First (OSPF) is a dynamic and inter-domain routing protocol with hierarchical architecture used in Internet networks routing. Area border router (ABR) had been proved to be an effective solution to the complicated network and scalability problem. Obviously, manual selection of ABR can not satisfy the dynamic change in the network load. A new scheme, based on the traffic engineering and flow splitting for the procedure of dynamic ABR switching for OSPF networks, is proposed in the paper. By …
