提起局域网主干的提速,人们想到最多的恐怕还是千兆以太网交换机。据IDC公司调查表明,目前3Com公司发售的千兆以太网交换机端口数排名为第一,销售额为第二。3Com公司亚太区市场总监法兰士先生这样认为,价廉是获得用户认可的一个因素,但更重要的因素则应归功于物美。尤其是CoreBuilder 9000,该交换机的背板总线高达560Gbps,是3Com公司高端产品的核心。于去年11月发布的CoreBuilder 9000是3Com公司高端产品的中坚力量。该交换机采用双引擎(Star-wired),全冗余式交换结构,共有14个插槽,在同一机架中可同时支持ATM、FDDI和千兆以太网。CoreBuilder 9000还支持3Com公司的Fast IP第三层交换技术,通过信道集成技术可将4个千兆以太网端口的带宽集成起来,达到4Gbps。因而适用于主干网的核心交换机。拥有4000个用户的
Mentioning the acceleration of LAN backbones, I’m afraid that most people think of Gigabit Ethernet switches. According to a survey conducted by IDC, the number of Gigabit Ethernet switch ports sold by 3Com is currently ranked first and sales are second. Mr. Francis, 3Com’s Director of Asia-Pacific Marketing, believes that low price is a factor for user acceptance, but more important factors should be attributed to Wumart. In particular, CoreBuilder 9000, the switch backplane bus up to 560Gbps, is the core of 3Com’s high-end products. The CoreBuilder 9000 released in November last year is the backbone of 3Com’s high-end products. The switch uses a Star-wired, fully redundant switch fabric with 14 slots and supports ATM, FDDI, and Gigabit Ethernet in the same chassis. CoreBuilder 9000 also supports 3Com’s Fast IP Layer 3 switching technology, which integrates the bandwidth of 4 Gigabit Ethernet ports to 4 Gbps through channel integration technology. This applies to the core switch of the backbone network. 4,000 users
