Chaos-Based Dynamic QoS Scheme and Simulating Analysis

摘要

This paper takes use of chaos related theories to analyze the real network traffic about its chaotic properties and prediction attributes. Owning to the good performance of chaos-based prediction in short term forecasting, the prediction-based DiffServ framework and the Dynamic QoS scheme are firstly given in the paper. The OPNET-based simulating result shows that the QoS per-formaces and the network's throughputs in heavy-load environment are all improved remarkably, comparing with the traditional static QoS configuring and measure-based dynamic QoS setting methods.
