Performance enhancement of flow control in 10GbE WANs
Rohan De Silva · 2004
Abstract:- This paper presents a new method of improving the flow control mechanism in 10 Gigabit Ethernet (10GbE) WANs. The ON/OFF control method prescribed by the standard leads to fluctuations of flow rates and the queue levels of the switches. Apart from the ON/OFF control, there are a few recent flow control mechanisms developed for the 10GbE networks in the literature. However, they do not comply with the present 10GbE standard as they require other quantities such as queue level to be included in the control frame. Our approach converts the fair share calculated by the switch to an equivalent pause time. As a result, our algorithm complies with the standard. Performance of this scheme has been studied via simulations and compared with the performance of the ON/OFF control method.
