Re: [5gangip] [lisp] Bandwidth savings with LISP

So I have been thinking about a compelling use-case for LISP header-compression and the super-framing feature (sorry for using my own term).

I have been told that the Radio Access Network (RAN) tends to be sensitive to overlay solutions due to large headers. I have also heard that there seems to be queuing behavior for the base-stations that send to UEs (i.e. phones). The fact that queuing is happening while waiting for a handoffs to occur can be a good opportunity to pack IP packets into super-frames to send over the RAN.

Using this solution means the eNodeB (base-station) and the UE (phone) would have to run LISP. I would like to hear comments from the WG. I have copied 5gangip to see if they have opinions.
