An in-depth look at flow aggregation for efficient quality of service

J.A. Cobb
Proceedings. Seventh International Conference on Network Protocols  
We investigate the preservation of quality of service guarantees to a flow of packets in the presence of flow aggregation.  ...  For efficiency, multiple flows, known as the constituent flows, are merged together resulting in a single aggregate flow.  ...  In this case, Theorem 5 reduces simply to S.t 1 For the induction case, we assume that Theorem 5 holds for all flows of depth less than depth.f, and for all flows at depth depth.f (including f) for  ...

On the aggregation of deterministic service flows

J. Schmitt, M. Karsten, R. Steinmetz
2001 Computer Communications  
An important distinction for the line of argument of our article is how we use the terms aggregation and grouping of flows.  ...  It is common belief that "flat" Quality of Service (QoS) architectures, as e.g. the IETF's Integrated Services architecture (IntServ), are not scalable to large networks as for example the global Internet  ...  Moreover, we have started to look at the aggregation of statistically guaranteed services.  ...
