This study investigates the problem of enabling Quality of Service (QoS) of multimediatraffic at the input port of high-performance input-queued packet switches using a simulation-basedevaluation. We focus on the possibility of assuring QoS of multimedia traffic in such switches byimplementing traffic prioritization at the input port where each input-queue has been modified toprovide a separate buffer for each of the service classes. The multimedia traffic can be categorized intothree classes based on its real-time properties and loss tolerance and assigned a separate queue for eachclass. We select appropriate models for each of three types of traffic: video, voice and data. Then, wepropose an efficient dynamic scheduling strategy by implementing multimedia traffic prioritization atthe input port of input-queued packet switches. Simulation-based comparisons show that while thestatic priority scheme is beneficial for highest priority class at the expense of the others, the dynamicprioritization serves fairly well all the classes in terms of delay and loss requirements. |
