Improving Quality of Service From TCP/IP Performance Degradation

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 highspeed hybrid networks, the authors propose a router-assisted congestion control protocol called Quick Flow Control Protocol (QFCP). The convergence of many traditional services over IP-based infrastructures drastically increases the amount of IP data traffic to be delivered to user clients, thus raising questions about the management of quality of service in such networks.
