A Weighted Fair Queue Management on DOCSIS Multi-downstream Channels

Abstract

In the home media network, Cable Modem is a useful device that most people have well-known. People expected network access as much less delayed as possible as what they can obtain. Therefore, the objective of effective bandwidth control becomes more and more important recently. In this paper, we are going to propose a methodology of Multi-downstream Service Algorithm (MDSA) to monitor the variation of input arrival rate to manage the bandwidth by Weighted Fair Queue (WFQ) based on a service workload. Applying this way, it is useful to refer to this paper of the bandwidth management method, assessing the input arrival rate that matches how the relative bandwidth is. Furthermore, the delayed time is effectively reduced accordingly.
