Paper Abstract

Traffic specification plays a crucial role in resource reservation for multimedia services over packet networks. The current development of QoS-guaranteed services still leaves a wide room for the selection of traffic specification. In this paper, we propose a new method to estimate the traffic specification of deterministic service. Usually, the estimation of traffic specification is independent of the QoS requirements, e.g. the delay bound. The proposed method is based on the point-of-view of the call admission control that takes the delay bound requirement into the estimation process. The solution is efficient in the sense that the resulting traffic specification is simple while still providing the excellent network utilization. Additionally, traffic smoothing is now a popular technique used to flatten the bursty video traffic, so reducing the potential congestion in the networks. We consider the traffic specification of video traffic in two cases: with traffic smoothing and without traffic smoothing. Initial experiments show that traffic smoothing does not result in significant changes in values of traffic specification. This highlights the importance of global burstiness of video traffic to the traffic parameters. The results of this research can be directly applied to some existing applications such as the integrated services of ATM and IETF.
