Abstract
The variety of traffic transferred via current telecommunication networks includes also voice, which should meet quality requirements. One of mechanisms, which can support QoS in current packet networks, is routing. There exist many routing proposals which should introduce the QoS into the network but practically they don't. Following paper presents the realization of simulation model for evaluation of a new routing algorithm DUMBRA (Dynamic Unattended Measurement Based Routing Algorithm). The proposed algorithm is based on dynamic measurements of differentiated class of serviced traffic and provides mechanisms which introduce QoS when the traffic fluctuations are present in the network. Also load balancing techniques have been introduced using KSP (k-shortest path) algorithm for utility optimization. The simulation model has been implemented in Omnet++ and results have been performed for many different network topologies. Selected results are presented.
