Abstract :
In this paper, the dependency of length of burst losses on the packet inter-arrival time in Voice over Internet Protocol (VoIP) is analyzed and modeled using the semi-Markov process. The model helps in predicting future loss lengths for a given pattern of packet arrivals at the queue. A simulation testbed with Cisco routers was setup to study the effect of packet inter-arrival time on burst loss patterns. The simulation results demonstrate that the length of burst losses increase for lower packet inter-arrival times, thereby demonstrating the temporal dependency of burst losses on the packet inter-arrival time.
