Other researchers have cast doubts on the overall improvement of the TCP Vegas proposals in sophisticated network environments. As part of my Ph. All rate information is measured in bits per second . Routers set sustainable rates for all traffic flows through them. Destinations return sustainable rates to sources.
Flows live long enough for routers to set accurate rate values.
In this framework, TCP must be discarded, as it is window-based. Routers must be extended to set sustainable rates. UDP is also unusable. However, my focus is on the methods used to set sustainable rates, and to show that the framework does reduce network congestion. The router which set the Rate field.
