We propose Adaptive Multi-level ECN, a new TCP congestion scheme as an extension to Multi-level Explicit Congestion Notification (MECN). MECN algo- rithm allows network operators to achieve high throughput with corresponding low delays. However, MECN average queue is sensitive to its parameter settings and the level of congestion, hence, no guarantees can be given about delay. Delay is a major component of the Quality of Service. Therefore, network operators would naturally like to have a rough estimate of the average delays in their congested routers. To achieve a predictable average delay with MECN, constant tuning of the parameters to adjust to current traffic conditions is needed. The goal of this paper is to solve the parameter tuning problem of the MECN. The analysis of our simulations shows that Adaptive MECN performs better than Adaptive RED.
