Abstract:
In order to define new switched Ethernet functions for data center use, the project IEEE802.1Qau [1] for congestion management is underway in the IEEE 802.1 standards committee. The aim of this project is to develop Ethernet congestion control algorithm for hardware implementation. Our focus is on Quantized Congestion Notification (QCN) algorithm, which is being considered by the IEEE802.1Qau standards for deployment in switched Ethernet networks. In this paper, based on simulation results, we show how QCN can dynamically control traffic flow, and we study QCN performances properties related to congestion control. In addition, we compare QCN behavior and performances to another backward congestion notification algorithm, which is Ethernet Congestion Management (ECM). The comparison between these two mechanisms is based on simulation results.
