[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.
