Abstract :
TCP is currently the dominate congestion control protocol for the Internet. However, as the Internet evolves into a high-speed wired-cum-wireless hybrid network, performance degradation problems of TCP have appeared, such as underutilizing high-speed links, regarding wireless loss as congestion signal, and unfairness among flows with different RTTs. In order to improve the quality of service for such high-speed hybrid networks, we propose a router-assisted congestion control protocol called quick flow control protocol (QFCP). Performance evaluation using network simulator NS-2 shows that QFCP can significantly shorten flow completion time, fairly allocate bandwidth resource, and be robust to non-congestion- related loss.
