【摘要】：随着信息网络的高速发展和普及,网络规模的扩大及各种宽带业务的需求激增,现有僵化、封闭、复杂、异构的网络无法提供与之相匹配的的高效动态网络服务。而灵活、开放、简单、可编程的软件定义网络(SDN)提出了一种解决目前网络问题的新体系和思想,其中OpenFlow是SDN架构中的南向接口的一种实现方式协议。又由于现阶段的IP和光传送网是单独分开控制的,且拥有不同架构、交换技术及控制管理机制,于是IP层与光层之间协作困难从而网络扩展性差、低效和资源利用率低。本文研究的基于OpenFlow的IP与光传送网统一控制把IP与光传送网作为一个全局整体而不再是分层独立的层次来统一控制,这样统一协作的网络性能优化、可扩展、高效且资源利用率高。 本文围绕基于OpenFlow的IP与光传送网统一控制的关键技术,进行的主要研究工作如下： (1).分析和设计了基于OpenFlow的IP与光传送网统一控制的网络架构和控制机制。在通常的包括应用层、控制层、数据层的SDN体系架构基础上,设计了基于OpenFlow的IP与光传送网统一控制的网络架构。并在统一控制的网络架构下详细分析设计了包括统一控制分组交换与电路交换、统一抽象、统一路径控制的统一控制机制。 (2).基于上述统一控制的网络架构及控制机制,分析了基于OpenFlow的IP与光传送网的统一控制平台的功能需求,并完成了统一控制平台的总体方案设计。 (3).完成了统一控制平台的OpenFlow通信处理模块的需求分析；在开源的NOX控制器基础上设计开发了OpenFlow通信处理模块,实现了控制平台与节点的连接处理、接收解析转发OpenFlow消息及封装下发OpenFlow消息的功能；并通过模拟测试验证了该模块的可行性。
[Abstract]:With the rapid development and popularization of information networks, the expansion of network scale and the rapid increase of demand for various broadband services, the existing rigid, closed, complex, heterogeneous networks can not provide matching efficient dynamic network services. The flexible, open, simple and programmable software definition network (SDN) presents a new architecture and idea to solve the current network problems, in which OpenFlow is a kind of implementation protocol of the southern interface in the SDN architecture. At present, IP and optical transport network are controlled separately and have different architecture, switching technology and control management mechanism, so it is difficult to cooperate between IP layer and optical layer, so the network expansibility is poor, the efficiency is low and the resource utilization is low. The unified control of IP and optical transport network based on OpenFlow is studied in this paper. The unified control of IP and optical transport network as a whole is no longer hierarchical and independent, so that the unified cooperative network performance optimization can be extended. High efficiency and high resource utilization. This paper focuses on the key technologies of unified control of IP and optical transport network based on OpenFlow. The main research work is as follows: (1). The network architecture and control mechanism of unified control between IP and optical transport network based on OpenFlow are analyzed and designed. On the basis of the usual SDN architecture including application layer, control layer and data layer, the network architecture of unified control between IP and optical transport network based on OpenFlow is designed. The unified control mechanism including unified control packet switching and circuit switching, unified abstraction and uniform path control is analyzed and designed in detail under the unified control network architecture. (2) Based on the above unified control network architecture and control mechanism, the functional requirements of the unified control platform of IP and optical transport network based on OpenFlow are analyzed, and the overall scheme design of the unified control platform is completed. (3) The requirement analysis of the OpenFlow communication processing module of the unified control platform is completed. Based on the open source NOX controller, the OpenFlow communication processing module is designed and developed, which realizes the connection processing between the control platform and the node, receives and forwards the OpenFlow message and encapsulates the OpenFlow message. The feasibility of the module is verified by simulation test.
