发布时间：2019-01-08 12:33
【摘要】：随着信息技术的飞速发展,证券、金融、电商、交通运输等行业对网络的依赖度不断提高,大量事关企业存亡的核心业务需要依靠网络支持。特别是在为数据中心所设计的大二层网络中,网络的安全稳定和高可靠性显得尤为重要。这网络协议能够快速应对故障,重新收敛网络拓扑。基于SPBM协议的NSR特性SPBM-NSR(Nonstop Routing for Shortest Path Bridging Mac in Mac)作为一种使用备份数据帮助网络恢复稳定的新技术手段,将不间断转发技术NSR应用到SPBM协议当中,使协议能够利用数据冗余的形式来提高所控制网络的安全性和稳定性。本文设计实现了应用于数据中心网络架设的SPBM-NSR。我们将功能相关的备份数据通过分包发送、组装解析的模式完成,采用多进程和多线程等手段提高系统效率,NSR使网络设备主备之间的切换时间缩短到进程级别,使得目标系统达到指定目的和性能。本文的主要工作包括：1.介绍了网络高可靠性技术发展现状和SPBM-NSR相关协议和技术原理；2.阐述了基于SPBM协议的NSR特性的需求分析与详细设计；3.描述NSR特性的具体实现,包括HA框架、数据备份、进程转换等功能；4.完成基于真实设备的系统功能验证试验及结果分析。通过真实设备的组网实验,SPBM-NSR达到了预期效果,并已经开始投入实际应用中。
[Abstract]:With the rapid development of information technology, securities, finance, e-commerce, transportation and other industries depend on the network constantly, a large number of core business related to the survival of enterprises need to rely on the network support. Especially in the two-layer network designed for the data center, the security, stability and high reliability of the network are very important. This network protocol can quickly deal with failures and reconverge the network topology. As a new technical means of using backup data to help network restore stability, SPBM-NSR (Nonstop Routing for Shortest Path Bridging Mac in Mac), a NSR feature based on SPBM protocol, applies uninterrupted forwarding technology (NSR) to SPBM protocol. The protocol can make use of the form of data redundancy to improve the security and stability of the controlled network. This paper designs and implements SPBM-NSR. for data center network installation. We use multi-process and multi-thread to improve system efficiency, and NSR can shorten the switching time between host and standby of network equipment to process level. Enables the target system to achieve the specified purpose and performance. The main work of this paper includes: 1. This paper introduces the status quo of network high reliability technology and SPBM-NSR protocols and technical principles. 2. The requirement analysis and detailed design of NSR characteristics based on SPBM protocol are described. 3. Describe the implementation of NSR features, including the HA framework, data backup, process transformation and other functions. 4. Complete system function verification test and result analysis based on real equipment. Through the real equipment networking experiment, SPBM-NSR has achieved the expected effect, and has been put into practical application.
