Traffic handling and network capacity in multi-service networks

This paper describes the impact of traffic handling mechanisms on network capacity for support of quality of service (QoS) in multi-service networks. The choice of which traffic handling strategy to employ requires a methodology that can be used to capture the trade-off between the different schemes and this is the focus of this paper. One key result of this work is that on the basis of capacity requirements, there is no significant difference between class-based traffic handling and per-flow traffic handling.
