通用成帧规程GFP的原理和应用

【摘要】 ITU-TG.7041通用成帧规程(GFP)是一种简便的可将高层客户数据信号适配到位/字节同步物理传输信道的通用方法,它能简化传输过程的映射处理,并有效地提高传输效率。文章介绍GFP的产生背景、帧格式和通用成帧原理及其应用。更多还原

【Abstract】 Generic Framing Procedure(GFP)is a simplecommon mechanismfor adaptingclient data signals into Bit-Synchronousor Octet-Synchronous physical transport channels.GFP reduces processing requirements of data link mappers/demappers and improves the efficiency of data transport.This article describes GFP background,frames tructure,generic framing principle and its application.更多还原
