【摘要】：随着信息技术的发展,现代网络管理对于提高网络单元利用率、故障定位和排查技术提出了更高的要求来确保网络的正常运行、网络优化、安全保障和服务质量。SDN(Software Defined Networking,软件定义网络)作为新兴的网络技术,给网络管理技术的发展带来了新的机遇和挑战。SDN将数据转发和控制相分离,由软件驱动的中央控制结点来自动化控制整个网络。但目前基于SDN技术的网络管理存在的问题是,SDN交换机缺乏标准网络管理协议,如何管理融合了SDN平台的网络已成为网络管理领域的研究和应用热点。本文从分析基于SDN技术的网络故障管理所面对问题出发,提出采用传统的SNMP网管协议和SDN RPC接口技术结合的方法,对融合了SDN平台的网络故障进行管理。通过分析系统需求,将该系统拆分成登录管理、拓扑管理、故障管理、SDN管理、数据管理模块五个部分。登录管理模块实现了用户操作权限的管理。拓扑管理模块实现了拓扑发现算法,完成对网络中设备的发现。故障管理模块通过SNMP方式对传统网络设备进行故障管理,采用SDN RPC接口与OVSDB结合的方式对SDN交换机设备进行故障管理。SDN管理模块通过开源的OpenFlow插件对SDN交换机设备中流的故障信息进行管理。数据管理模块完成了对拓扑数据及故障数据的管理。作者独立完成了该系统的登录管理、拓扑管理、故障管理和SDN管理模块的开发工作。本文探索了目前研究和应用的热点SDN技术及其在网络管理系统中的应用,在实验室SDN平台上实现了网络故障管理原型系统,对SDN网络管理接口的实现进行了有益的尝试,为进一步的工程应用实践奠定了基础。经过测试系统在实验室已成功运行。
[Abstract]:With the development of information technology, modern network management has put forward higher requirements to improve the utilization of network units, fault location and troubleshooting technology to ensure the normal operation of the network, network optimization, As a new network technology, it brings new opportunities and challenges to the development of network management technology. SDN separates data forwarding and control. A central control node driven by software automates the entire network. However, the problem of network management based on SDN technology is the lack of standard network management protocol. How to manage the network integrated with SDN platform has become a research and application hotspot in the field of network management. Based on the analysis of the problems in network fault management based on SDN technology, this paper proposes a method of combining the traditional SNMP network management protocol and SDN RPC interface technology to manage the network fault which integrates the SDN platform. By analyzing the requirements of the system, the system is divided into five parts: login management, topology management, fault management SDN management and data management module. The login management module realizes the management of user operation rights. The topology management module realizes the topology discovery algorithm and realizes the discovery of the devices in the network. The fault management module manages the fault of the traditional network equipment by SNMP. The SDN RPC interface and OVSDB are used to manage the fault information of the SDN switch devices through the open source OpenFlow plug-in. Data management module completes the management of topology data and fault data. The author has independently completed the development of login management, topology management, fault management and SDN management module. This paper explores the current research and application of the hot SDN technology and its application in the network management system, realizes the prototype system of network fault management on the laboratory SDN platform, and makes a beneficial attempt to realize the SDN network management interface. It lays a foundation for further engineering practice. The tested system has been successfully run in the laboratory.
