数据中心网络的目标是将大量的数据中心服务器互连起来，并为上层应用提供高效、容错的路由服务。为了克服目前实践中树结构的问题，提出了许多新的网络架构，以胖树，BCube等为代表。在这些新架构中的一个一致的主题是，大量的网络设备用于实现1：1的超额订阅比。然而，在大多数时候，数据中心的流量远低于峰值。闲置的网络设备将浪费大量的能源，这是现在许多数据中心所有者的头痛问题。在本文中，我们讨论了如何节省能源消耗的高密度数据中心网络的路由的角度。我们称这种路由为能量感知路由。其关键思想是使用尽可能少的网络设备来提供路由服务，而不会/很少牺牲网络性能。同时，空闲的网络设备可以关闭或进入睡眠模式以节省能源。建立了数据中心网络中的能量感知路由模型，并设计了一种启发式算法来实现该思想。我们在典型数据中心网络中的仿真表明，能量感知路由可以有效地节省网络设备的功耗。
The goal of data center network is to interconnect the massive number of data center servers, and provide efficient and fault-tolerant routing service to upper-layer applications. To overcome the problem of tree architecture in current practice, many new network architectures are proposed, represented by Fat-Tree, BCube, and etc. A consistent theme in these new architectures is that a large number of network devices are used to achieve 1:1 oversubscription ratio. However, at most time, data center traffic is far below the peak value. The idle network devices will waste significant amount of energy, which is now a headache for many data center owners. In this paper, we discuss how to save energy consumption in high-density data center networks in a routing perspective. We call this kind of routing energy-aware routing. The key idea is to use as few network devices to provide the routing service as possible, with no/little sacrifice on the network performance. Meanwhile, the idle network devices can be shutdown or put into sleep mode for energy saving. We establish the model of energy-aware routing in data center network, and design a heuristic algorithm to achieve the idea. Our simulation in typical data center networks shows that energy-aware routing can effectively save power consumed by network devices.
