Dynamic Configuration of Red Parameters


Our work focuses on an adaptive approach of RED namely ARED (Adaptive RED) that performs a constant tuning of RED parameters according to the traffic load. ARED requires no hypothesis on the type of traffic, which diminishes its dependency on the scenario parameters such as the bandwidth, the round-trip time and the number of active connections. Our goal is to find a simple extension to ARED in order to improve the predictability of performance measures like queueing delay and delay jitter without sacrificing the loss rate. To achieve this goal, we propose a new algorithm that sets the RED parameters and evaluate it by extensive simulations. Our results show that compared to the original ARED, our algorithm can stabilize the queue size, keep it away from buffer overflow and underflow, and achieves a more predictable average queue size without substantially increasing the loss rate.
