RD-RACE:An Improved Rate Control Mechanism in Ethernet
Atm R · Computer Engineering and Applications Journal · 2005
With the rapid development of Ethernet technique,the rate control scheme becomes a technical focus in de-ploying Traffic Engineering.As the traditional bucket-based rate control algorithm drop multi-packets of the same TCP flow when the traffic exceeds the assigned bit-rate,it causes frequently timeout and lowers the throughput of TCP.In or-der to improve the performance of TCP in the rate-controlled environment ,an improved bucket-based rate control algo-rithm called RD-RACE(Restricted-Drop RAte Control in Ethernet)is purposed in this paper.RD-RACE can reduce the number of packets dropped in the same round of the same flow and increase the throughput of TCP.Simulation shows the algorithm works well.
