Abstract

An actual trend in networking is the aggregation of traffic streams. This allows not only to keep the core equipment simple while increasing the complexity at the network edge but also to overcome scalability issues in the core network. However, traffic flows within aggregates are not distinguishable any more and therefore experience all fairly the same service quality which can be harmful in multi-service networks. In this paper several different strategies for traffic aggregation are compared in an enterprise network scenario. In order to apply realistic traffic sources, we carried out measurements of multimedia traffic streams, the results of which are presented and discussed in detail with respect to different traffic characteristics. Finally, we performed simulations on several different aggregation strategies in order to show that it is possible to satisfy the individual QoS requirements of all real-time flows while maintaining an overall high load even with only two classes.
