Each of the hot - swappable forwarding media cards in the qbrt - based multigigabit router is effectively a separate router 在基于qbrt的千兆位路由器中，每块热插拔的转发介质卡实际上是一个独立的路由器。
2.
Elimination of the next - hop route lookup bottleneck - - even under worst - case traffic conditions - - combined with the nonblocking 1g bit / sec forwarding paths allow the multigigabit router to achieve wire - speed performance 消除下一跳跃路由查找的瓶颈（甚至在最坏的流量条件下） ，加上无阻塞1千兆位/秒转发通道，让千兆位路由器获得线速性能。
