1. 项目背景 某公司在北京建立了总部，后在广州建立了分中心，并在全国各省都设 立了办事处。总部设有研发、市场、供应链、售后等 4 个部门，统一进行 IP 及业务资源的规划和分配。 公司规模在 2016 年快速发展，业务数据量和公司访问量增长巨大。为 了更好管理数据，提供服务，公司决定建立自己的小型数据中心及云计算服 务平台，以达到快速、可靠交换数据，以及增强业务部署弹性的目的。 总部、分中心及某办事处的网络架设（实际设备）网络拓扑结构如图 2.1 所示。 其中两台 S5800 交换机编号为 S4、S5，用于服务器高速接入；两台 S3600V2 编号为 S2、S3，作为总部的核心交换机；两台 MSR2630 路由器编号 为 R2、R3，作为总部的核心路由器；一台 S3600V2 编号为 S1，作为总部接 入交换机；一台 MSR2630 路由器编号为 R1，作为某办事处路由器。
