And, in particular, there are a *lot* of folk to which transport is layer
2 or 3 (OTN = optical transport network); I'm currently working on something
where I have to be very carful every time I use the word transport because
sometimes it is end-to-end (L4), sometimes edge-to-edge (L3), and sometimes
a lightpath (L2, sort of).

And in the same context a link between IP routers (switched lightpath) is not
necessarily the same as a glass fiber link between photonic cross-connects.
