Comparison of some dynamic routing methods in broadband networks

For broadband services delivery, specially for interactive services that are expected in the near future, high QoS at low cost could be the goal of dynamic routing deployment. The quality of service (QoS) performances of the network, from the user point of view, can be described by throughput (rate of information transfer), average delay, maximum delay, delay jitter, probability of losing information (unacceptable bit error rate, packet loss probability, etc.) and various other characteristics. In this paper the problem of route choice between source and target node is solved using two different time and state dependent dynamic routing methods. Their comparison is done regarding the total delay between two network nodes for chosen routes.
