Efficient Capacity Provisioning in Delay Constrained IP Networks
Irena Atov, Richard Harris · Swinburne figshare (Swinburne University of Technology) · 2004
This paper addresses the problem of capacity provisioning in a QoS enabled IP network, subject to satisfying varying performance requirements for different traffic classes. These performance requirements are viewed in terms of mean end-to-end delays required for the various traffic classes or in terms of random variations of their delays (i.e., jitter) or a combination of both. The accuracy of the model is investigated by means of a simulation study over an extended range of test cases for different traffic load characteristics and traffic intensities at the nodes. The results demonstrate the capability of the model in guaranteeing the end-to-end delay requirements for the traffic classes.
