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.

I tend to agree.

[PA] Hey folks, 5G is going for slices for many good reasons. One of these is to avoid stacking headers… especially in the RAN.

Let’s not conflate running LISP and super-framing. I think running LISP (but not on the UE) is really an easy deployable solution. That is a separate topic for discussion. This thread was focusing on super-framing.

[PA] No objection to use all these wonderful things you propose in the CORE, but there is a lot of processing before that and there’s where my part kicks in, right? ;-)

Right, we will have several presentations at the 5gangip BOF discussing this.

[PA] Hey folks, what does 5G core actually mean? For me it will be the core of the 5G network, which is currently TBD. So instead of thinking about replacing something that does not exist, why don’t we argue that this core part of the future 5G network would benefit for supporting LISP? ;-)

Yes, I and many are aware of the opportunity.

[PA] Me too, just trying to put things into (yet another) perspective (with no claim to absolute truth or completeness). ;-)

Thanks,
Dino
