| 摘 要： | 因特网地址查询技术是导致IP路由器速度降低的限制因素之一。用于地址查询的传统算法已经不能适应日益增加的网速要求。基于IXP2400硬件哈希单元的分类规则表查询技术，采用5元组对FEC的分类，将分类从原IP转发中独立出来，极大提高了网络效率，同时也相对容易实现对传统路由器的升级。

| Abstract: | Internet address lookup is one of the limiting factors,which cause the IP routers to speed down.Traditional algorithms used for the address lookup already do not comply with ever-increasing speed demands.The paper puts forward a technology of Classification Rules Table Query based on hash unit,which is a hardware in IXP2400.It adopts a 5-tuple classifier for FEC,which is independent of IP Forwarding.It produces significant improvement in network speed and is comparatively easy to upgrade from the traditiona... |
