基于OpenFlow的域间协作网络管理调控系统的设计与实现
发布时间：2019-02-15 07:04
【摘要】：目前在具有多个自治域的网络环境下,跨域的网络管理没有一套良好的解决方案。现有的研究成果主要是域间协作式的通信信令机制,但是尚无完备的应用并且缺乏可用网络环境对其进行验证。因此,结合OpenFlow技术,提出了域间协作网络管理调控机制,该机制是一套包含从协作请求的创建、各域之间的分发交互到最终执行请求的完整解决方案。协作请求创建时使用管理策略描述语言来制定策略,分发时使用抽象拓扑和路径计算,请求和答复的消息遵循已有的域间协作网络信令机制,而执行时则运用OpenFlow支持可编程式的集中网络控制的特点,将需求组装成指令交给OpenFlow交换机去执行。 并且开发和实现了域间协作网络管理调控系统。系统的3个重要组成部分为域间管理代理、适配器和控制器。域间管理代理负责接收和响应协作请求还有在域和域之间传递消息；适配器负责解析协作请求并将请求中包含的管理策略映射成为OpenFlow交换机可执行指令；控制器则负责和OpenFlow交换机通信,采集OpenFlow网络信息、下发OpenFlow交换机指令。 通过搭建OpenFlow多域网络环境,并在此之上进行系统的测试,证明了系统的健壮、有效,同时也验证了域间协作网络管理调控机制的可行性。
[Abstract]:At present, in the network environment with multiple autonomous domains, cross-domain network management does not have a good solution. The existing research results are mainly inter-domain cooperative communication signaling mechanism, but there is no complete application and lack of network environment to verify it. Therefore, based on the OpenFlow technology, an inter-domain cooperative network management control mechanism is proposed, which is a complete solution from the creation of collaborative requests, the distribution interaction between domains to the final execution of requests. When the cooperation request is created, the management policy description language is used to formulate the policy, and the abstract topology and path calculation are used for distribution. The message of request and reply follows the existing signaling mechanism of inter-domain cooperative network. The execution time uses the characteristics of OpenFlow to support programmable centralized network control and assembles the requirements into instructions to be executed by the OpenFlow switch. And developed and implemented the inter-domain cooperative network management and control system. Three important components of the system are inter-domain management agents, adapters and controllers. The inter-domain management agent is responsible for receiving and responding to the cooperation request and delivering messages between the domain and the domain, and the adapter is responsible for resolving the cooperation request and mapping the management policy contained in the request into the executable instruction of the OpenFlow switch. The controller is responsible for communicating with OpenFlow switches, collecting OpenFlow network information and issuing OpenFlow switch instructions. By setting up the OpenFlow multi-domain network environment and testing the system on this basis, the system is proved to be robust and effective, and the feasibility of inter-domain cooperative network management and regulation mechanism is also verified.
