First paper on the edge-to-edge congestion control architecture. Introduces Explicit Edge Control (EEC). With EEC, the bottleneck marks all packets when the queue length exceeds a threshold. The edges then shape traffic to alleviate the congestion at the bottleneck. Stateful methods such as FRED can be employed at the edges to control end systems without imposing stateful mechanisms at the bottleneck. The included simulations show that EEC significantly scales TCP performance in terms of fairness and loss rates beyond that possible with FRED placed at the bottleneck, isolates misbehaving TCP or UDP flows, corrects unfairness due to heterogeneous delay, and experiences less beat-down over multiple bottlenecks than end-to-end control alone.
