Rate Based Feedback: Some Experimental Evaluation With NetFPGA

Free registration required

Executive Summary

Transport protocols that use explicit rate feedback are a promising alternative to the protocols which use implicit, packet loss based feedback. A key issue in the design of rate controlled communication networks is how new flows may be admitted at a fair and high starting rate. In this paper, for the management of new flows the authors present a modified NetFPGA Rate Control Protocol (RCP) implementation for a recently proposed admission management process at the routers. Using this implementation, they investigate the admission process of new flows in rate controlled networks. They conduct experimental tests across a range of bandwidth-delay product environments, and also deal with the arrival of a large number of flows.
