Abstract

In the process of enterprise digital transformation, the traditional three-layer data center network can hardly meet the requirements of rapid business iteration in terms of elasticity, security, and efficiency. To address the problems caused by virtualization, such as traffic surge, limited migration, insufficient scalability, and weak internal network security, this study proposes a software-defined networking (SDN) upgrade scheme based on VMware NSX according to the actual conditions of the existing network and on the premise of making full use of the available hardware. The scheme adopts the Spine-Leaf architecture and GENEVE Overlay technology to build a new generation data center network featuring high performance, high reliability, high security, and elastic scalability. Performance test results show that the upgraded network significantly improves throughput and concurrency while reducing latency, effectively supporting virtualized and distributed applications as well as future business evolution. The results of this study can serve as an engineering reference for similar enterprise data center network upgrades and as a typical teaching case for higher vocational network technology courses.
