The key point in ensuring good quality of service in a network is to understand the relationship between demand, capacity and performance. An enhanced flow-aware network is perceived as a necessary alternative to the complex standardized QoS architectures, and sufficient to meet user performance requirements in a cost-effective manner. This flow-aware network would provide flow-level performance guarantees for real-time and data application, without requiring any class of service distinction nor relying on signalled traffic specifications, thus preserving the best effort interface to the network. Implementing per-flow fair queueing and limiting the impact of overload through flow-level admission control is an efficient way to realize this objective. In this short talk, we present the basic concepts of a flow-aware network, and give the rationales which have lead to this proposal. This represents the ground which inspired the work I have done with James Roberts during my PhD in France Telecom labs.
