Abstract

This paper proposes and evaluates a new algorithm on measuring the packet loss burstiness to be applied in ITU E-Model. The algorithm reveals the packet loss burstiness characteristics directly from the packet loss pattern. A new parameter called equivalent random packet loss is obtained based on the burstiness measurement. This new parameter is used in the E-Model to replace the random probability of packet loss to calculate the R-Factor and MOS value. The enhanced E-Model achieves an improved measurement accuracy under bursty packet loss conditions. Simulation results are presented in the later part to show the effectiveness of the proposed model.
