This paper proposes an approach of highspeed routing lookup based on TCAM. The approach can get a lookup speed of 100M times per second and satisfy the sending speed required by the OC48 and OC192 interfaces. By using two layer structure of the index table and the map table to storage the next hop information of the routers, it reduces the storage spaces greatly and makes a good generalization to IPv6. The paper also discusses the problem of routing update of TCAM. An updating algorithm is proposed, which has a time complexity of O(W/2) in the worst case(where W indicates the number of prefix length sets) and improves the updating ability of TCAM effectively.

基于TCAM技术提出一个高速路由查找方案。该方案可以达到每秒钟100M次的查找速度,满足OC48和OC192接口的线速转发要求。方案使用了索引表和映射表的二级结构存储路由的下一跳信息,大大减小了存储空间,同时对IPv6具有很好的扩展性。对TCAM的路由更新问题进行了讨论,提出一个最坏情况下O(W 2)的更新算法(W为前缀长度集合的数目),有效地提高了TCAM的更新性能。

By analyzing the existing algorithm and the characteristic of a classifier, a fast five dimension algorithm of packet classification based on the IXP1200 network processor is proposed, which gains wire-forward rate.

通过对现有报文分类算法的分析和性能比较,并结合分类规则所具有的特性提出了一种新的基于IXP1200网络处理器的多维报文分类算法,称为PCBNP(packet classification based on network processor),并达到了报文的线速转发.算法除了通过减少分类的规则数和分类的域宽来加快分类的速度外,还采用重定向排序索引、位向量表示匹配规则等技术来加快分类的速度,特别是利用了规则的动态分布规律来确定查找报文字段的顺序,通过先查找“分布最均匀的字段”来达到在所有的字段被查找之前提前找到报文匹配的过滤规则的目的.算法具有高速、多维和可扩展的特性,与现有的算法比较,该算法在综合性能上优于已有的报文分类算法.
