【摘要】：云计算,大数据等高新互联网技术对于底层网络规模,性能,服务质量等业务承载需求越来越高,传统网络架构由于缺乏灵活性而难以满足上述需求。在这样的背景下催生了软件定义网络(Software Defined Network,SDN)。在软件定义网络中,单个控制器集中管控虽然为新业务的部署与实验提供了便利,却也容易成为网络系统的性能瓶颈。为此人们开始积极探索集群控制器技术,集群控制器的应用能够有效解决单个控制器面临的单点失效、安全性低、易于遭受攻击、可扩展性较差等问题。然而在大多主流集群架构中,"控制器-交换机"管控关系都是静态配置的。本文研究了 SDN集群控制器管控映射静态固化配置的缺点,分析了管控关系静态固化配置无法适应数据中心等真实网络场景中变化的流量需求,为了适应峰值流量而大量部署控制器则易于造成资源能源的大量浪费等问题。提出并实现了一种SDN集群控制器弹性控制节能技术。部署运行在OpenDaylight集群控制器上。实验表明,应用该技术,集群控制器中的工作节点个数能够动态适应数据面的流量变化,在数据面请求持续处于较低水平时,有选择性的休眠部分节点,柔化"控制器-交换机"管控关系映射,达到了构建绿色节能集群控制器的目标。
[Abstract]:Cloud computing, big data and other high-tech Internet technology demand more and more services for the underlying network scale, performance, service quality and other services. Traditional network architecture is difficult to meet the above needs because of lack of flexibility. In this context, the software definition network (Software Defined Network, SDN) has been spawned. In software defined network, centralized control of single controller provides convenience for new business deployment and experiment, but it is also easy to become a performance bottleneck of network system. Therefore, people begin to explore the cluster controller technology. The application of cluster controller can effectively solve the single point failure, low security, vulnerable to attack and poor scalability of single controller. However, in most mainstream cluster architectures, "controller switch" control relationships are static configuration. This paper studies the disadvantages of SDN cluster controller control map static curing configuration, analysis of the relationship between the static configuration control curing cannot adapt to the changes in Data Center real network in the scene of the traffic demand, in order to adapt to the peak flow and the deployment of a large number of controller is easy to cause a great waste of energy resources and other issues. A new energy saving technology for elastic control of SDN cluster controller is proposed and realized. The deployment runs on the OpenDaylight cluster controller. Experimental results show that the application of the technology, the number of nodes in cluster controller can dynamically adapt to the data flow change request, continued at a low level in the data plane, selective dormant part of nodes "controller switch control" to soften the relationship mapping, to build green energy saving target cluster controller.
