Comments on "Discrete-Time Queueing Systems and Their Networks"

Abstract

In the paper Bharath-Kumar presented an analysis of a discrete buffered system of infinite capacity, where the length of the packets is drawn from a geometric distribution and the packets leaving the resource have to be retransmitted with some probability. In this correspondence an analysis of the same system is given which applies for a general packet length distribution, and where the length of a packet remains the same each time it is retransmitted, as opposed to Bharath-Kumar's model where the retransmission packet lengths are independently chosen.
