【摘要】：目前互联网中网络设备的体系结构是封闭的,不利于网络创新.软件定义的网络(SDN)对互联网垂直紧耦合的结构进行了解耦,同时将控制层面及其协议的实现开放.SDN促进互联网创新和快速演进的思想已被学术界和工业界广泛接受.OpenFlow作为SDN的代表性实例,已被全球多所大学和研究机构部署.但OpenFlow域内集中控制的模式,随着部署规模的增大,控制平面的可扩展性越来越明显.为此本文采用了负载均衡的思想解决该可扩展性问题.提出了一种高度可扩展的架构MSDN.MSDN首先对数据流初始化请求进行分流,然后通过共享的整个网络视图对请求并行处理,并对网络视图进行了数据集群,从而彻底解决了控制平面的可扩展性问题.文章最后的实验模拟证明了方案的可行性.
[Abstract]:At present, the network equipment architecture in the Internet is closed, which is not conducive to network innovation. SDN) decoupled the structure of the vertical tight coupling of the Internet. At the same time, the idea of opening up the control level and its protocols to promote the innovation and rapid evolution of the Internet has been widely accepted by academia and industry as a representative example of SDN, and has been deployed by many universities and research institutions around the world. However, with the increase of deployment scale, the expansibility of the control plane becomes more and more obvious in the centralized control mode in OpenFlow domain. Therefore, this paper adopts the idea of load balancing to solve the scalability problem. In this paper, a highly extensible architecture, MSDN.MSDN, is proposed, which firstly distributes the initialization request of the data stream, then processes the request in parallel through the shared whole network view, and carries on the data cluster to the network view. Thus, the extensibility of the control plane is solved thoroughly. Finally, the feasibility of the scheme is proved by the experimental simulation.
