路由器
路由器是一种连接多个网络或网段的网络设备，它能将不同网络或网段之间的数据信息进行“翻译”，以使它们能够相互“读”懂对方的数据，从而构成一个更大的网络。 路由器有两大典型功能，即数据通道功能和控制功能。数据通道功能包括转发决定、背板转发以及输出链路调度等，一般由特定的硬件来完成；控制功能一般用软件来实现，包括与相邻路由器之间的信息交换、系统配置、系统管理等。 多少年来，路由器的发展有起有伏。90年代中期，传统路由器成为制约因特网发展的瓶颈。ATM交换机取而代之，成为IP骨干网的核心，路由器变成了配角。 进入90年代末期，Internet规模进一步扩大，流量每半年翻一番，ATM网又成为瓶颈，路由器东山再起，Gbps路由交换机在1997年面世后，人 们又开始以Gbps路由交换机取代ATM交换机，架构以路由器为核心的骨干网。 （Quelle: www.linkwan.com)
