Performance analysis of a new implementation efficient capacity allocation protocol for multimedia traffic in ATM networks

A. Burrell et al. (1993; 1994) described an implementation efficient capacity allocation protocol for multimedia traffic (voice, video, high and low speed data). The protocol determines the capacity allocation of each traffic dynamically, and induces moving boundaries within prespecified and fixed channel frames. The channel frames are selected to satisfy the jittering constraints of all the traffic, such as voice, video and high versus low speed data. The high level protocol, in conjunction with the channel frame structure and the specifics of the transmission policy, may satisfy all traffic and QOSs and may simultaneously attain high channel utilization, for certain variability conditions of the traffic rates and at relatively low implementation cost. In the work presented, the system stability, channel utilization, traffic rejection rate and packet/cell delay are examined. Performance evaluation results are presented. >
