Solving VoIP QoS and Scalability Issues in Backbone Networks

Abstract
Providing quality of service should be one of the main objectives when deploying sensitive applications into the network. Since network performance parameters are subject to frequent change, in this chapter we propose a novel approach to routing sensitive VoIP traffic in large networks. Our approach takes measured delay and jitter into consideration and we establish an overlay of the original network to route primarily VoIP traffic. This is achieved by first modeling the probability distributions of network performance parameters and then by calculating the best paths by means of graph algorithm utilizing aspects. Our approach also identifies weak network areas not suitable for VoIP deployment which can be subject to future network improvements.
