基于CAM存储器的高速路由搜索引擎设计

The Design of High Speed Router Searching Engine Based in CAM Memory

路由搜索是路由器工作中的核心模块,而其中对路由表和地址表的高速路由搜索是整个路由器工作的瓶颈模块。针对该核心模块提高运行速度,提出了一种基于相连存储器CAM的高速网络搜索引擎设计方案,搜索引擎控制的控制器采用FPGA实现。文中详细介绍了高速路由搜索引擎的实现过程和工作过程。

The route search is the core module in the router working, while the high speed route search for the router table and the address table is the entire router work bottleneck module. With the purpose of accelerating this core module speed, this paper proposes a design of high speed network searching engine based on the associative memory CAM, the controller of which is utilized by FPGA. In the paper, the author introduces in detail the high speed route search engine implementing and running process.
