The thing is, commercially, it is not always feasible to 
deploy IPoDWDM everywhere.

In a network that has its own fibre (local and national), it 
may make sense to run rings over dark fibre if you have 
plenty of fibre, and in other cases (particularly over 
longer spans), you would be better off driving it across 
DWDM infrastructure. Whether that is a transponder (grey 
light) or a colored wave, depends on all the other stuff I 
mentioned in a previous post.

I think a hybrid is more likely for most:

	- Some IPoDWDM
	- Some dark fibre
	- Some EoDWDM (grey light)
