With the rapid growth of the communication equipment performance, it is possible that
communication networks, which use TCP/IP, will be able to provide real-time applications
such as the broadcasting of a multi-media traffic. These applications are sensitive to
transmission delay and its variance, thus estimating QoS is very important. In this paper, we
evaluate the performance of an IP-based multimedia network in terms of the end-to-end
mean delivery time and the utilization of communication equipments.
