I'm sorry, I have again a question.
Suppose the mapping of ETH frames in OPU2.
The ETH frames are delineate by GFP (to detect start / end of the ETH
frame). Also, GFP convert the ETH traffic from VBR to CBR.
I would say that GFP is synchronous to the ETH frames.
Suppose we have OPU2, then ODU2 and OTU2.
So, we have to adapt the GFP/ETH timing to OPU2/ODU2/OTU2.
Can we use GMP for that?
