Abstract
In this paper, we investigate the performance of
an IEEE802.3 shared-bandwidth hub under a mixed
data/real-time traffic load. For the regular data nodes
we assume an exponentially distributed packet length
with a Poisson arrival. For the video sources, we
assumed MPEG encoded video sources at 30 frames
per second. We used simulation to study the network
performance under the above-mentioned load. We
used 2 different protocols, the standard IEEE802.3
and PCSMA, which is suitable for real-time traffic.
