Next generation optical transport networks require a light-weight traffic adaptation mechanism to multiplex low-rate electrical signals into large capacity optical channels. The mechanism must be flexible, low complexity and able to support a variety of data signals operating at rates from 10Mbps to 10Gps and beyond. The Generic Framing Procedure (GFP) is an ITU-T/ANSI standard specially designed to fulfill this role. This document provides an overview of the problem, the procedures and the target applications.
