一种数据封装新格式——GFP

Generic Framing Procedure(GFP):A New Way of Transporting IP over WDM Opti cal Networks

介绍了一种新的用于宽带传输的流量适配协议-通用成帧过程(GFP),它提供了有效的和QoS友好的机制,将各种不同物理层或逻辑链路层信号映射到字节同步通道上,也支持基于用户管理目的的基本客户控制功能。介绍了GFP的技术特点,并与当前应用最为普遍的一些适配协议进行了比较。

This article introduces GFP, a new traffic adapting protocol for broadband tra nsportation. GFP pro-videsa effective and Qos-friendly mechanism to map di-vers e physical and logical link layer signalsto a byte-syn-chronouschannel, and al so support basic client control function. The technology featuresof GFP, and c ompari-son with other wide-used adapting protocol are also dis-cussed.
