摘要:
随着网络规模的加大,网络节点不断增多,网络中需要进行管控和处理的数据也就越多,因此对控制平面的数据处理能力的要求也越来越高。 如果控制平面只有一个集中的控制器来完成工作,其处理能力有限,在面对大规模复杂网络时,必将产生系统性能瓶颈。 为了解决这一问题,提出了一种新的控制平面设计方案,即功能模块化控制平面。 功能模块化控制平面将控制器内部按照功能划分成不同的子功能模块,各子功能模块能够独立部署,统一进行调度,对外实现逻辑集中化,内部又可以实现灵活扩展,进一步提高控制器的灵活性、可靠性以及整体性能。 研究了功能模块化控制平面的总体模型设计和通信机制,最终通过搭建拓扑对功能模块化控制器进行测试,验证了该方案的可行性和有效性。
Abstract:
With the increase of the network scale and the increasing number of network nodes,the data to be controlled and processed in the network is increased,so the requirement for the data processing of the control plane is also higher and higher. If the control plane only has one single centralized controller to complete the work,its processing capacity is limited. When facing large-scale complex network,it will produce a systematic bottleneck. In order to solve this problem,a design scheme for new control plane,a functional and modularized control plane is proposed,which is divided into different sub function modules. Each one can be deployed independently and unified scheduling. The external logic can be centralized and the internal modules can be flexibly loaded. The ultimate goal is to improve the flexibility and reliability of the controller. The overall model design and communication mechanism of the modular control plane are studied.Finally,the functional modular controller is tested by constructing the topology and the feasibility and effectiveness of the proposed scheme is verified.
