Cisco公司如今支配着路由器市场。不过,该公司对第3层交换技术的重要性做出了错误估计。使公司置身于对手的攻击之下,该公司面临着许多反应敏捷、渴望成功的竞争对手。几乎到1998年中期Cisco公司才推出它的第3层交换设备(8500系列交换机)。从直接挑战Cisco公司的竞争对手所处的有利形势来看(如Bay网络公司和3Com公司).Cisco必须准备500磅重的敢死队以便突围。过去 Cisco now dominates the router market. However, the company made an incorrect estimate of the importance of Layer 3 switching technology. Putting the company under the attack of its opponents, the company faces many agile and eager competitors. It was only in mid-1998 that Cisco introduced its Layer 3 switching equipment (8500 series switches). From the standpoint of directly challenging Cisco’s competitors (such as Bay Networks and 3Com), Cisco must prepare a 500-pound death squad in order to break through. past
