Analytical models for jitter and QoS requirements with IPP and MMPP-2 traffics

Today, One of the most important performance measures in the new burst traffic gets to 3G and 4G systems is the End-to-End jitter. However, in order to study and analyze Jitter, many works and models have been devoted to estimate and evaluate this parameter. In this paper, analytical formulas for jitter of interrupted Poisson traffic (IPP) and MMPP-2 are presented. We provide Jitter approximation for The IPP Model. Moreover, we found that the jitter calculated directly using the IPP process is almost equal to that found by the EPP model. We have found that jitter can be a decreasing function of load. Simulation results show that the delay and jitter behave inversely which confirms the result already found in [8]. Finally, we found value of the average arrival rate and service rate required to provide flexible and efficient QoS guarantees for VoIP.
