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...
Unlike other explicit congestion controllers that depend on the estimation of network parameters (such as link latency, bottleneck bandwidth, packet loss, or the number of flows) to compute the allowed source sending rate, the IntelRate controller can avoid this while maintaining good stability and robustness. Simulation results have verified these performances. In this paper, we theoretically investigate...
As an explicit congestion control protocol, API-RCP (Adaptive PI rate control protocol) was originally proposed for best-effort traffic control in the IP networks with high bandwidth-delay product. The original API-RCP adopts a truncated network model for IP router in order to simplify the control system design while still achieving various designed performance measures at steady-state. A further...
TCP becomes inefficient and prone to instability when its bandwidth-delay product increases. By sending explicit congestion information from routers to end hosts, both XCP and API-RCP have been proposed to solve the stability issue of TCP in high bandwidth-delay product networks. Since the estimation errors of the network parameters are unavoidable, we would like to design a robust controller to address...
Electric market dynamics is important for market administrators to maintain market reliability, forecast problems and take remedy actions. Equilibrium analysis models have been built in the past to find market equilibrium. However, to achieve the goal of deregulation, not only should market equilibrium be identified, but also achievability of equilibrium and market transition process to equilibrium...
