基于EVPN和VXLAN的新一代云网融合技术及其应用部署

The New Generation Cloud Network Fusion Technology Based on EVPN and VXLAN and Its Application Deployment

随着网络流量的激增,传统的“接入—汇聚—核心”构成的3层数据通信网络模型已经无法满足实际应用。大量虚拟机的构建和微服务架构的流行,促使数据流动呈现“东西”向。使用软件定义网络(Software Defined Network,SDN)技术构建新型数据中心成为云网融合的一种可行方案。针对传统数据通信网络面临的困境,探讨了基于SDN技术的数据中心的架构和实际应用,以期为相关研究提供帮助。

With the rapid increase of network traffic,the three-layer data communication network model based on the traditional "access convergence core" can not meet the new requirements for technology proposed by practical applications.The construction of a large number of virtual machines and the popularity of microservice architecture promote the data flow to show a "east-west" direction.Using Software Defined Network(SDN) technology to build a new data center has become a feasible solution.Aiming at the difficulties faced by the traditional data communication network,this paper discusses the architecture and construction of the data center based on SDN technology combined with practical applications,with a view to providing help for related research.
