命名数据网络（NDN）最近受到了相当大的关注，主要是由于其内置的缓存，预计将实现广泛和透明的运营商控制的缓存。一个重要的研究挑战是减少NDN网络消耗的功率，因为已经表明NDN的名称前缀匹配和缓存是耗电的。作为实现节能NDN网络的第一步，在本文中，我们开发了一个多核软件NDN路由器的功耗模型。通过应用这个模型来分析缓存如何降低功耗，我们报告说，缓存可以降低NDN网络的功耗，如果路由器的功耗是成比例的负载和缓存的计算是轻的转发。
Named data networking (NDN) has received considerable attention recently, mainly due to its built-in caching, which is expected to enable widespread and transparent operator-controlled caching. One of the important research challenges is to reduce the amount of power consumed by NDN networks as it has been shown that NDN's name prefix matching and caching are power-hungry. As a first step to achieving power-efficient NDN networks, in this paper, we develop a power consumption model of a multicore software NDN router. By applying this model to analyze how caching reduces power, we report that caching can reduce power consumption of an NDN network if the power consumption of routers is in proportion to their load and the computation of caching is as light as that of forwarding.
