Item Summary

Title:Global multi-hop scheduling for improving network utilization and Qos
Authors:Li, Jiang
Date Issued:2008
Abstract:In this thesis, we present an analytical framework to provide statistical end-to-end delay guarantees to network traffic with a novel packet scheduling scheme, namely the Global multi-hop Scheduling (GMS). We first introduce background literature, then present the framework and performance analysis of this proposed scheduling mechanism, which considers bandwidth resources at both upstream and downstream hops, reserves expected bandwidth to admitted flows, assigns expected deadlines to packets differently from traditional scheduling schemes, and decides packet service order based on the path of each flow. The framework of this thesis can serve as the criterion to provide statistical bounds for the delay violation probability. We will show that this novel scheduling mechanism can provide much better Quality of Service (Qos) performance over current scheduling schemes in both aggregated flows and specific flows with strict Qos requirement, by both theoretic analysis and simulations.
