Design Analysis of 1 0Gbps Forwarding Engine with FPGA
基于FPGA实现的10Gbps高速转发引擎设计分析

The 10Gbps forwarding engine is one of the most challenge task in terabit router design. In order to design a 10Gbps forwarding engine with FPGA, the transmission bandwidth requirement between each elements in FPGA, IP look-up time, header processing cycle number and the up-to-date development of FPGA are all analyzed in detail. So the number of fiber to provide enough transmission bandwidth is calculated, a fast IP look-up scheme is presented and a header processing module of parallel and pipeline structure is provided. Finally the implementing scheme of the 10Gbps forwarding engine is proposed.
