Stability Analysis and Evaluation of the IntelRate Controller for High-Speed Heterogeneous Networks

The IntelRate controller does not require to evaluate some critical network parameters (such as the bottleneck bandwidth and the number of flows in the link) while performing well to the sudden changes in traffic load or bandwidth. This paper demonstrates theoretically that the IntelRate control system is globally asymptotically stable. Opnet simulations verify 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 network changes.
