The distributions of the number of consecutive received\r\nand lost packets (namely gap and burst) are modeled from the\r\ntransition probabilities of two-state and four-state model.\r\nMeasurements show that both models describe adequately the burst\r\ndistribution, but the decay of gap distribution for non-homogeneous\r\nlosses is better fit by the four-state model. The respective\r\nprobabilities of transition between states for each model were\r\nestimated with a proposed algorithm from a set of monitored VoIP\r\ncalls in order to obtain representative minimum, maximum and\r\naverage values for both models.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 42, 2010"}
