Abstract :
This paper investigates the joint use of push-out mechanisms with random early detection (RED)-like discarding policies to support service differentiation in the Internet. The efficiency and the degree of differentiation of a complete sharing with push-out, a RIO (RED with in/out) and a RIO with push-out queues are assessed. Results indicate that push-out used jointly with RED-like policies does not improve the performance.
