3Com:升级方案分两步实施:首先是路由核心层,使用CoreBuilder 3500替代已有的路由器,通过SuperStack ⅡSwitch 2000s与令牌环及其它工作组交换机实现联接,CoreBuilder 3500相当于局域骨干网的路由器,支持实时多媒体传输;第二步是采用CoreBuilder 5000/9000s和SuperStack Ⅱ1000/3000s进行配线柜升级以满足桌面级需求。就进步发展,该公司支持千兆以太网。 BayNetworks:对于升级该公司明显属稳扎稳打型,首先安装Accelar1200路由交换机作为第2层交换机以替代现有的以太网集线路、交换机等,然后
3Com: upgrade program implemented in two steps: first, the routing core layer, using CoreBuilder 3500 to replace the existing router, through SuperStack Ⅱ Switch 2000s and Token Ring and other workgroup switches to achieve connectivity, CoreBuilder 3500 is equivalent to the local area network backbone router , Support for real-time multimedia transmission; the second step is to use CoreBuilder 5000 / 9000s and SuperStack Ⅱ1000 / 3000s for wiring closet upgrades to meet the desktop needs. As it progressed, the company supported Gigabit Ethernet. BayNetworks: The upgrade for this company is clearly a steady hit, first installing the Accelar1200 routing switch as a Layer 2 switch to replace an existing Ethernet set of lines, switches, etc., and then
