Abstract:
It is unquestioned that the importance of IP network will further increase and that it will serve as a
platform for more and more services, requiring different types and degrees of service quality. Modern
architectures and protocols are being standardized, which aims at guaranteeing the quality of service delivered to
users. In this paper, we investigate the queueing behaviour found in IP output buffers. This queueing increases
because multiple streams of packets with different length are being multiplexed together. We develop balance
equations for the state of the system, from which we derive packet loss and delay results. To analyze these types
of behaviour, we study the discrete-time version of the “classical” queue model M/M/1/k called Geo/Gx/1/k, where
Gx denotes a different packet length distribution defined on a range between a minimum and maximum value.
