摘要
从实现网络传输过程中的能耗比例计算理念以及降低网络中数据的重复传输2个角度综述了降低网络能耗的方法。实现能耗比例计算理念的技术包括边缘网络的网络存在性代理技术、以太网节能技术和核心网络的节能路由技术。人类对数据访问的异步性需求以及对数据访问呈现重尾分布的规律从宏观上为减少数据的重复传输提供了前提。比较了互联网上现有的和处于实验阶段的多种内容分发方式,包括CDN、P2P、CCN和双结构互联网,探讨了它们对提高网络传输能效的作用。
Approaches for reducing network energy consumption were surveyed from two aspects： realizing energy-proportional computing in data transmission, and reducing duplicated data transmission in the network. Approaches endeavor to realize energy-proportional computing include network presence proxy in edge networks, energy-efficient Ethernet and energy-aware routing techniques in core network. The asynchronous data access nature and the heavy-tailed frequency distribution for data access offer opportunities to reduce duplicated data transmission. Several existing and experimental content distribution mechanisms （e.g. ,CDN, P2P, CCN and dually structured internet） and their effects in enhancing energy efficiency in data transmission, were compared and investigated.
