摘要： 传统网络环境不能较好地兼顾网络性能和能耗。为此,提出一种新的网络评价算法。在软件定义网络环境中,利用启发式算法,使用流表机制动态调节广域网的网络拓扑,实现网络性能和能耗的调节,并对其性能和能耗的调节效果进行评价。实验结果表明,与传统网络只关注网络性能或能耗的算法相比,该算法能够实现网络性能和能耗的动态调节,实现简单,并且链路利用率较高。

Abstract: In traditional network environment,network performance and energy consumption can not be taken into account.In order to solve this problem,a new designed network evaluation algorithm is proposed in this paper.In Software Defined Network(SDN),a heuristic algorithm and flow table mechanism are proposed to dynamically adjust network performance and energy consumption.Experimental results show that the algorithm can achieve dynamic adjustment of network performance and energy consumption compared to traditional network only focusing on network performance or energy consumption.The algorithm achieves simple implementation and high link utilization.

Key words: Software Defined Network(SDN), energy consumption, dynamic regulation, heuristic algorithm, network evaluation
