摘要
根据光传输网的发展现状和趋势,详细比较了通用成帧协议两种映射方式的优缺点,并分析了GFPT透明传输方式在OTN传输网的应用前景。重点阐述了GFPT协议的FPGA设计实现方法。设计的GFPT模块功能在Xilinx的Virtex4 FPGA上得到验证,工作频率达到166MHz。
Based on the development status and trend of optical transport network, the advantages and disadvantages of GFP＇ s two modes were compared in detail. The application prospect of GFPT transparent transmission method used in the optical transport network was analyzed. The FPGA design and implementation of the GFPT were discussed. The function of this module was verified on Xillinx Virtex4 board, and the working frequency could reach 166 MHz.
