Abstract We address the accommodation of multimedia traffic by ATM broadband networks. We isolate a single network channel and we search for capacity allocation/transmission multiplexing policies which satisfy all traffic QOSs with simultaneous high utilization of channel capacity resources, in the presence of variable traffic rates. Towards that direction, we superimpose a high-level traffic-monitoring protocol which determines capacity allocations for each traffic category, dynamically. The latter protocol has sequential and implementation-efficient characteristics, and induces moving boundaries within prespecified and fixed channel frames. The channel frames are selected to satisfy the jittering constraints of all the traffics, 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 QOSs and may simultaneously attain high channel utilization, for certain variability conditions of the traffic rates and at relatively low implementation cost. Performance analysis as well as numerical evaluations are provided.
