System Content and Packet Delay in Discrete-Time Queues with Session-Based Arrivals

TLDR
This paper considers a discrete-time queueing model with infinite storage capacity and one single output line, which can for instance be applied to study the traffic of a file server, where one file download by a user corresponds to one session.
Abstract
This paper considers a discrete-time queueing model with infinite storage capacity and one single output line. Users can start and end sessions during which they are active and send packets to the queueing system. Each active user generates a random but strictly positive number of packets per time slot: this results in a session-based arrival process of packets. This model can for instance be applied to study the traffic of a file server, where one file download by a user corresponds to one session. The steady-state probability generating functions of the number of active sessions, buffer occupancy (number of packets stored in the buffer) and packet delay are derived. We also derive an approximation for the tail probabilities of the buffer occupancy. This allows us to study the influence of the different system parameters: some examples are presented.

TL;DR: A technique for the exact analysis of the system is introduced, which is essentially a generating-functions approach that uses an infinite-dimensional state description and it is shown that the exact nature of the message-length distribution has a significant impact on the multiplexer performance.
