Study of Delay and Loss Behavior of Internet Switch Markovian Modelling Using Circulant Markov Modulated Poisson Process (CMMPP)
... ABSTRACT Most of the classical self-similar traffic models are asymptotic in nature. Therefore, it is crucial for an appropri- ate buffer design of a switch and queuing based performance evaluation. In this paper, we ...

Hidden Markov models for time series of counts with excess zeros
