Abstract

In integrated networks, a traffic control strategy has to allocate network resources according to the characteristics of input traffic. In this paper, a traffic control strategy using a burstiness characterization based on a virtual queue principle is examined. This approach provides the necessary link between network resources allocation and traffic control. Using the leaky bucket mechanism, a general strategy based on the burstiness characterization, called the LB-Dynamic policy, is developed for packet scheduling. This traffic control strategy monitors the allocated network resources and guarantees the network performance of each established connection, irrespective of the traffic intensity and arrival patterns of incoming packets. Simulation studies demonstrate that the LB-Dynamic policy is able to provide the requested service quality for heterogeneous traffic.
