    Multimedia services include usually several components, e.g., video, voice, data and control. Characteristics of these components may vary substantially for which reason it has been difficult to develop comprehensive performance models for multimedia traffic. Additionally, queuing at various network nodes changes characteristics of the bit streams and quite often increases burstiness of the traffic. Due to the bursty nature of multimedia traffic, buffering easily becomes a critical issue. Since no good models are available, this paper approaches the buffering problem by carrying out measurements to study the effect of different multimedia streams on buffering. MMPP distribution has been chosen to simulate performance of multimedia traffic.
