Sri,

Bear in mind that "industry" has different meanings depending on the
context. For ILA, and probably for LISP, the intent is to build a
generic protocol that can be used across variety of use cases in the
networking industry which hasn't uniformly adopted CUPS. It's pretty
obvious that we'd want to leverage a single data plane control plane
for these (isn't that the point of generic protocols :-) ). The CUPS
actually architecture helps a lot here by creating a clean well
abstracted interface that should make it straightforward to adapt an
ILA control plane. I think our architecture where we define ILA as an
NF reflects that.
