【摘要】：云計算,大數(shù)據(jù)等高新互聯(lián)網(wǎng)技術對于底層網(wǎng)絡規(guī)模,性能,服務質(zhì)量等業(yè)務承載需求越來越高,傳統(tǒng)網(wǎng)絡架構由于缺乏靈活性而難以滿足上述需求。在這樣的背景下催生了軟件定義網(wǎng)絡(Software Defined Network,SDN)。在軟件定義網(wǎng)絡中,單個控制器集中管控雖然為新業(yè)務的部署與實驗提供了便利,卻也容易成為網(wǎng)絡系統(tǒng)的性能瓶頸。為此人們開始積極探索集群控制器技術,集群控制器的應用能夠有效解決單個控制器面臨的單點失效、安全性低、易于遭受攻擊、可擴展性較差等問題。然而在大多主流集群架構中,"控制器-交換機"管控關系都是靜態(tài)配置的。本文研究了 SDN集群控制器管控映射靜態(tài)固化配置的缺點,分析了管控關系靜態(tài)固化配置無法適應數(shù)據(jù)中心等真實網(wǎng)絡場景中變化的流量需求,為了適應峰值流量而大量部署控制器則易于造成資源能源的大量浪費等問題。提出并實現(xiàn)了一種SDN集群控制器彈性控制節(jié)能技術。部署運行在OpenDaylight集群控制器上。實驗表明,應用該技術,集群控制器中的工作節(jié)點個數(shù)能夠動態(tài)適應數(shù)據(jù)面的流量變化,在數(shù)據(jù)面請求持續(xù)處于較低水平時,有選擇性的休眠部分節(jié)點,柔化"控制器-交換機"管控關系映射,達到了構建綠色節(jié)能集群控制器的目標。
[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.
