一种基于快速重路由的域内节能路由算法

降低互联网的能耗成为亟待解决的一个科学问题，已有的路由节能方案存在会不同程度地降低网络性能，如网络拥塞、路由振荡、路由可用性和流量分布不均匀等问题，以及需要网络的实时流量信息，从而导致算法复杂度较高的问题。设计一种基于快速重路由的绿色节能方案EEIPFRR，兼顾节能、网络性能和算法复杂度。实验结果表明，与DLF算法比较，EEIPFRR算法不仅可以降低网络能耗，并且具有较小的路径拉伸度、较低的算法复杂度和较小的最大链路利用率。

Energy efficient scheme based on IP fast reroute in intra-domain link state networks

Reducing the energy consumption of the Internet has become an urgent problem. However, the existing energy efficient routing algorithms are facing the following two problems: all of them will degrade the network performance in varying forms, such as network congestion, routing flap, routing availability and uneven traffic distribution; and all of them require real-time traffic information, which lead to high complexity of the algorithm. Therefore, this paper designed a green energy efficient scheme EEIPFRR which was based on IP fast reroute, took into account the energy saving, network performance and algorithm complexity. The experimental results show that compared with DLF algorithm, it can not only reduce network energy consumption, but also have less path stretch, lower algorithm complexity and maximum link utilization.
