摘要

IP查找是保证IP路由器性能的关键任务之一。有人建议使用tcam来实现IP查找加速器,用于IP转发。本文提出并研究了一种新的基于tcam的ip查找方案MSMB-LPT。仿真结果表明,MSMB-LPT方案在加速和功耗方面明显优于现有的MSMB-PT方案。这些性能改进是以更低的成本实现的。

An improved TCAM-based IP lookup engine
IP lookup is a key task in packet processing to guarantee the high performance of the IP routers. It has been proposed to use TCAMs to implement IP-lookup accelerators for IP forwarding. In the paper, a new TCAM-based IP-lookup scheme MSMB-LPT is proposed and studied. It is shown that MSMB-LPT scheme significantly improve the performance of the state-of-art MSMB-PT scheme in terms of speedup and power consumption by simulations. These performance improvements are achieved with reduced cost.
