摘要
介绍了企业网的发展现状,讨论了企业网部署中普遍采用的MSTP+VRRP双核心网络架构,通过详细分析核心层、汇聚层和接入层各层之间可能出现的网络拓扑设计方案,从网络各层部署的细节,对双核心架构的高可用性进行了分析.在讨论核心层与汇聚层拓扑部署时,分析了环状拓扑与网状拓扑部署下性能的异同,并总结了各自的应用情景;在分析汇聚层与接入层拓扑部署时,对三角状拓扑部署的可用性进行了简单分析.给出了网状拓扑部署这种过度冗余的部署方式,指出该网络部署方式并不适用于接入层部署.
The paper introduces the status of the enterprise network, discusses the widely utilized enterprise network with dual - core （ MSTP and VRRP） , and analyzes the high availability of the dual - core enterprise network through a detailed analysis of the network topology design among the core layer, the convergence layer and the access layer. While discussing the network topology design between the core layer and the convergence layer, the article analyzes similarities and differences between the ring topology and mesh topology, and summarizes their application situation ; While discussing the network topology design between the convergence layer and access layer, the paper analyzes the availability of triangular topology, provides the topology of this excessive redundancy situation and indicates that the topology is not appropriate in the access layer.
