Power is becoming increasingly as important, if not more important than performance in many digital systems ranging from PCs and servers to Internet routers and embedded systems-on-a-chip. While there has been substantial research exploring the power efficiency of the processing and memory elements of digital systems, research investigating the powerconsumption of communication elements has been lagging. As a wide range of digital systems becomes increasingly interconnected, it is nowboth timely and critical to explore power-aware interconnection networks.In this proposal, we outline our plans to research, develop and build self-regulating power-aware interconnection networks that trade off power and performance automatically while meeting design constraints. In these networks, power-aware router and link mechanisms export knobs by which network power and performance can be adjusted. Policies then control these knobs to deliver network power-performance that meet design goals. Self-regulating power-aware networks alleviate designers from the daunting task of reconciling two highly divergent goals -high performance, and low power.In highlighting and demonstrating the importance of power awareness in networks, our proposed research advances a deeper understanding of networks from a fresh perspective, with a potential for high-impact contributions in research. In addition, we see our research leading to power efficiency being an integral part of networking curriculum.

在许多数字系统中，从个人电脑和服务器到互联网路由器和嵌入式片上系统，电源变得越来越重要，甚至比性能更重要。虽然已经有大量研究探索数字系统处理和存储元件的功率效率，但对通信元件功耗的研究却一直滞后。随着各种数字系统的互联程度越来越高，探索功率感知互连网络变得及时且至关重要。在本提案中，我们概述了研究、开发和构建自调节功率感知互连网络的计划，该网络可以在满足设计约束的同时自动权衡功率和性能。在这些网络中，功率感知路由器和链路机制输出旋钮，通过这些旋钮可以调整网络功率和性能。然后，策略控制这些旋钮以提供满足设计目标的网络功率性能。自调节功率感知网络使设计人员摆脱了协调两个高度不同的目标（高性能和低功耗）的艰巨任务。在强调和展示功率感知在网络中的重要性时，我们提出的研究从一个全新的角度推进了对网络的更深入的理解，并有可能在研究中做出高影响力的贡献。此外，我们认为我们的研究使电源效率成为网络课程不可或缺的一部分。
