Free registration required

Executive Summary

This paper shows how to prevent oscillation in adaptive routing algorithm. When a network implements load sensitive routing, traffic fluctuations are often observed which give rise to routing instability. This results in poor route selection and an overall degradation of network performance. In this paper, the authors presented three different stability factors that can be used to provide stable routing by preventing oscillation in adaptive routing algorithms. The performance is studied computationally for various networks with different number of nodes under static traffic model. In all the experiments the stability factor III shows better results in terms of iterations.
