Abstract
This paper studies self-configuring random early detection (RED) gateways for quality of service (QoS) networks. Existing work only considers the of RED gateways for networks with best effort flows. This paper focuses on QoS networks in which both assured and best effort flows co-exist. RED with in/out (RIO) is an extension of RED for QoS networks, which maintains two parameter sets (i.e., in-profile and out-of-profile) for different classes of traffic. We find that fixed and low out-of-profile thresholds limit best-effort throughput when assured flows are frequently absent or the amount of assured flows is small. We then propose an adaptive scheme called adaptive-RIO to adjust the parameters according to network dynamics. From the simulation, adaptive-RIO performs better than RIO in terms of higher best-effort throughput and total throughput while ensuring the committed rate of assured flows. © 2003 IEEE.
