OSPF-based model of adaptive routing and possibility for stable network operations
Nihad Borovina, Sead Kreso · 2005
This paper deals with adaptive routing based on OSPF protocol. The main goal of adaptive routing is to provide network distribution of IP traffic so that links are as evenly as possible loaded without loosing IP packets in the network. This paper presents the routing model which collect the parameters from the network and, accordingly, calculates the values of OSPF link weight. To achieve adaptability, the fuzzy logic is used. Adaptive model is tested on the network simulator, and the simulation results indicate significant enhancements while using adaptive routing, comparing to simple OSPF routing based on pre-defined link weights. The network stability and enhancements increasing the model stability are especially analyzed.
