What is gfp protocol

The details are as follows:. By introducing the concept of multiple service levels, GFP can implement the simple function of bandwidth control. This method is more efficient than de-frame delimitation with a special frame identifier.

It is also possible to define different service levels for data streams in GFP without using the upper-layer protocol to view the service level of the data stream. This advantage comes from the fact that GFP adopts a specific frame delimiting method. In PPP, it checks every byte of the payload. If there are bytes with the same frame identifier, it will process this byte, making the load longer and unpredictable.

When the performance of the latter is significantly better than the former, The mapping protocol uses PPP, and when there is no significant difference in the transmission performance between the two, the mapping protocol uses GFP.
