Comprehensive Queueing Analysis for a Partial Buffer System with Discrete Markovian Arrival Processes

Abstract

In this paper, we evaluate the performance of a partial buffer system with finite capacity, deterministic service time and multiple sources. Each source is modeled by a Discrete Markovian Arrival Process (D-MAP). We evaluate the queueing system for several traffic composition and different sizes of the shared buffer area. Various traffic types are considered, including VBR (Yariable 1!it Rate) sources with periodical or negative exponential correlation functions and CBR (Constant 1!it Rate) traffic with fixed interarrival cell emission. The probability distribution of the waiting time and the cell loss probability of each source are determined.
