低延迟、高吞吐量和公平性是数据中心网络的严格性能要求。为了让Web应用程序继续蓬勃发展，数据中心必须通过应对这些挑战来保持有效性。虽然大多数挑战已经由数据中心特定的传输协议（例如DCTCP）处理，但这些传输协议不是数据中心用户的默认选项。自由选择传输协议需要仔细考虑有效的解决方案。我们认为，排队方案在第二层交换机举行的关键，以解决这些问题。因此，在本文中，我们提出了FaLL，排队方案的数据中心网络，满足以下性能要求：公平共享带宽，低排队延迟，高吞吐量，易于部署。FaLL使用效率模块、公平模块和基于目标延迟的丢弃方案来满足这些目标。FaLL需要非常少量的状态信息。通过在真实的测试平台上的严格实验，我们表明FaLL在各种网络条件下优于各种对等解决方案。
Low latency, high throughput, and fairness are the stringent performance requirements of data center networks. For web applications continue to thrive, data center must remain effective by addressing these challenges. While most of the challenges have been handled by data center specific transport protocols (e.g. DCTCP), these transport protocols are not default options for data center users. Free choice of transport protocols demands careful consideration for an effective solution. We argue that queuing scheme at layer-2 switches hold the key to address these issues. Therefore, in this paper, we present FaLL, a queuing scheme for data center networks that meets following performance requirements: fair share of bandwidth, low queuing latency, high throughput, and ease of deployment. FaLL uses an efficiency module, a fairness module and a target delay based dropping scheme to meet these goals. FaLL requires very small amount of state information. Through rigorous experiments on real testbed, we show that FaLL outperforms various peer solutions in variety of network conditions.
