They assumed only mean loss as the system parameter to message losses. This paper deals with the QoS of failure detectors when the probabilistic behavior of messages is extended with the probability distribution of loss burst lengths. The proposed Markov chain model, which treats loss bursts, is presented in this paper. Some simulation results are commented. } }
