Abstract
Forwarding system is one of key components for high-performance router. In this paper, the architecture of router is described first. Then, software system of centralized router and the process of a packet are analyzed. At the end, the performance bottleneck of centralized router is pointed out. To get better performance, we propose a fast-forwarding mechanism to increase the speed of packet, which takes the idea of "once route, multi-forwarding".
