摘要

IP查找是核心路由器系统中的一个重要问题。已经提出了几种新的算法来解决这个问题。与内存访问次数、路由插入/删除时间和内存使用情况相比,这些方法各有优缺点。从高速前缀查找的角度出发,我们提出了基于多比特尝试的双模表和基于硬件的快速IP地址查找方法的改进查找方案。由于该方案是一种优化的当前前缀长度分布,因此该方案与真实的互联网流量密切相关。

High speed lookup scheme based on two-pass for core router
IP lookup is an important issue in core router systems. Several new algorithms have been proposed to solve this problem. These approaches have strength and weakness compared with the number of memory access times, route insertion/deletion time, and memory usage fact. In a point of view high-speed prefix lookup, we propose the improved lookup scheme using dual-mode tables based on multibit tries and the fast hardware-based IP address lookup approach. The proposed scheme is very related to real Internet traffics because this scheme is an optimized current prefix length distributions.
