With the increasing abundance of the application services and the evolution of the transport technology

it is badly needed that a simple

flexible and efficient generic framing technology should adapt various application services to the physical layer. In this paper

a new framing method of ITU-T G.7041 Generic Framing Procedure （GFP） is introduced

with its technical features and advantages. Then we discuss the application of GFP in MSTP. Finally

related issues for GFP in the emerging Data over OTN resolution are analyzed

raising the concept to realize the efficient division and utilization for bandwidth in Data over OTN

in the way of building LSP in the GFP layer.
