Abstract:
The Forwarding Information Base (FIB) of backbone routers has been rapidly growing in size. An ideal IP lookup algorithm should achieve constant, yet small, IP lookup time
and on-chip memory usage. However, no prior IP lookup algorithm achieves both requirements at the same time. In this paper, we first propose SAIL, a Splitting Approach to IP Lookup. One splitting is along the dimension of the lookup process, namely finding the prefix length and finding the next hop, and another splitting is along the dimension of prefix length, namely IP lookup on prefixes of length less than or equal to 24 and IP lookup on prefixes of length longer than 24. Second, we propose a suite of algorithms for IP lookup based on our SAIL framework. Third, plemented our algorithms on four platforms: CPU, FPGA, GPU, and many-core.
该论文提出一种SAIL路由表查找算法,比现有算法快7~60倍,发表在网络方向顶级会议SIGCOMM上,基金委信息学部网站进行了新闻报道。
