Abstract

This paper introduces an approach to managing quality-of-service (QoS) for a residential video-on-demand (VoD) service employing MPEG-2 transport streams using an experimental asynchronous transfer mode (ATM)/asymmetric digital subscriber line (ADSL) access network testbed. The paper examines the complex multilayer propagation of ATM layer parameters over an underlying physical layer and their relationship to video quality. The results obtained from the testbed provide an important insight into the factors relevant to the provisioning and management of new multiservice network infrastructures. Overall, these results contribute to an understanding of the multilayer QoS relationship and provide a basis for comparison with, and development of, similar systems. The paper proposes a method to aid the comparison of results based on a multilayer QoS approach
