【摘要】：随着数据中心规模的不断扩大,能耗问题已经成为制约其发展的瓶颈之一.因此,数据中心网络节能成为研究领域的一个重要方向,也产生了很多的研究成果.其中相当一部分方法是从寻找最小能耗路径入手,却往往陷入NPC或NP难问题的窘境.为了避免此类情况,从Fat Tree构架的网络拓扑特点入手,提出"独立路径集"的概念,并以路径资源管理的理念对数据中心网络节能机制展开研究.利用软件定义网络对网络节点的监控能力,着眼全局控制,根据实时流量情况动态地调整数据中心网络资源配置.在满足当前流量需求的同时,关闭或休眠闲置的交换机,从而达到节能的目的.通过仿真实验及相关分析,证明该方法具备可行性和可操作性,为进一步拓展研究打下了基础.
[Abstract]:With the continuous expansion of data center scale, energy consumption has become one of the bottlenecks restricting its development. Therefore, energy saving of data center network has become an important direction in the field of research. There are also a lot of research results. Many of the methods are to find the minimum energy consumption path, but often fall into the dilemma of NPC or NP-hard problems, in order to avoid this kind of situation. Based on the network topology characteristics of Fat Tree, the concept of "independent path set" is proposed. Based on the idea of path resource management, the energy saving mechanism of data center network is studied, and the monitoring ability of network nodes is defined by software to focus on global control. Dynamically adjust the resource configuration of the data center network according to the real-time traffic situation. Close or sleep the idle switch while meeting the current traffic requirements. Through the simulation experiment and related analysis, it is proved that the method is feasible and feasible, which lays a foundation for further development of the research.
