随着互联网服务规模的扩大，托管互联网服务的能源消耗正成为一个紧迫的问题。动态服务器配置技术可以有效地关闭不必要的服务器以节省能源。此类技术主要针对请求-响应服务进行研究，在托管大量长期 TCP 连接的连接服务器环境中面临着挑战。在本文中，我们基于从已部署的 Windows Live Messenger 收集的真实数据跟踪来描述连接服务器的独特属性、性能和电源模型。使用这些模型，我们设计服务器配置和负载分配算法，并研究它们之间的微妙交互。我们证明，我们的算法可以节省大量能源，而不会牺牲用户体验。
Energy consumption in hosting Internet services is becoming a pressing issue as these services scale up. Dynamic server provisioning techniques are effective in turning off unnecessary servers to save energy. Such techniques, mostly studied for request-response services, face challenges in the context of connection servers that host a large number of long-lived TCP connections. In this paper, we characterize unique properties, performance, and power models of connection servers, based on a real data trace collected from the deployed Windows Live Messenger. Using the models, we design server provisioning and load dispatching algorithms and study subtle interactions between them. We show that our algorithms can save a significant amount of energy without sacrificing user experiences.
