Dynamic bandwidth allocation in high speed integrated service networks

A threshold-based dynamic allocation policy, called DQT, in which the bandwidth allocated to each class of traffic is altered based on the queue occupancy at the end of a frame is studied. Two classes of traffic with different quality of service (QOS) requirements are considered, and it is shown that the performance of the proposed scheme is better than that of a static allocation scheme. The performance of the scheme and the parameter sensitivity are studied under both stationary and nonstationary conditions, and it is indicated how parameter values can be chosen.<
