As the network infrastructure has been consuming more and more power, various schemes have been proposed to improve the power efficiency of network devices. Many schemes put links to sleep when idle and wake them up when needed. A presumption in these schemes, though, is that router's line cards can be waken up very quickly. However, through systematic measurement of a major vendor's high-end routers,...

With the rapid growth of the Internet, the update messages in backbone routers become more and more frequent due to the ever-increasing dynamic changes on network topologies and new emerging functionalities of the Internet. In addition, update messages often come as a burst. Update action interrupts the packet lookup operation in the router's data plane, thus inefficient incremental update algorithm...
Virtual router research has drawn increasing attention in recent years, and the most challenging issues of virtual routers are compression, lookup, and incremental update of 10∼200 routing tables. In this paper, we propose a set of solutions to achieve that storage, lookup time, and update time don't expand to 10∼200 times, but reduce to 1∼2 times.
