1.2 COMPUTER AND INFORMATION SCIENCE
The aim of this paper is to describe how QoS (Quality of Service) metrics such as packet delay can be used to optimise the routing algorithms used in a network where IP Television (IPTV) content is being distributed. We outline the usage of metric instrumentation in a network to gauge the bandwidth limits of the network and how to use this information to generate a model of network link utilisation. Furthermore, we show that as the link utilisation rates change in our network model, we can modify the network routing algorithms to optimise the distribution of IPTV content to end-users.
