指数带宽缩放是互联网增长和受欢迎程度的基本驱动力。然而，带宽的增加伴随着功耗的增加，尽管系统设计为解决电力需求的持续设计努力，但仍有巨大的技术挑战仍然有可能减缓未来的带宽增长。在本文中，我们描述了当今路由器中的功率和相关的热量管理挑战。我们主张一种解决此问题的广泛方法，其中包括使电力意识成为网络设计和配置以及网络协议的设计和实现的主要目标。我们通过提供两个标准路由器平台的功率需求的案例研究来支持我们的论点，这使我们能够为路由器功耗创建通用模型。我们将此模型应用于一组目标网络配置，并使用混合整数优化技术来研究静态网络设计和动态路由中的功耗，性能和鲁棒性。我们的结果表明，通过包括电力意识，可以在运营网络中节省大量能源。
Exponential bandwidth scaling has been a fundamental driver of the growth and popularity of the Internet. However, increases in bandwidth have been accompanied by increases in power consumption, and despite sustained system design efforts to address power demand, significant technological challenges remain that threaten to slow future bandwidth growth. In this paper we describe the power and associated heat management challenges in today's routers. We advocate a broad approach to addressing this problem that includes making power-awareness a primary objective in the design and configuration of networks, and in the design and implementation of network protocols. We support our arguments by providing a case study of power demands of two standard router platforms that enables us to create a generic model for router power consumption. We apply this model in a set of target network configurations and use mixed integer optimization techniques to investigate power consumption, performance and robustness in static network design and in dynamic routing. Our results indicate the potential for significant power savings in operational networks by including power-awareness.
