Stability Analysis and Evaluation of the IntelRate Controller for High-Speed Heterogeneous Networks
The IntelRate controller can avoid the evaluation of critical network parameters (such as the bottleneck bandwidth or the number of flows in the link) while performing well to the sudden changes in traffic load or bandwidth. This paper theoretically demonstrates that the IntelRate control system is also globally asymptotically stable. Opnet simulation confirms that the IntelRate controller can maintain stable operations regardless of the traffic conditions. Finally, comparison demonstrates that the IntelRate controller can have more stable performance than other exiting controllers upon large network changes.
