Re: Signaling Message Fragmentation

Fred - If there is interest to do that work and the chair's are ok with it, I'll not object to that work.

Regards
Sri

OK, then it sounds like you would agree that fixing tunnel MTU once and for
all would be a good thing?

Thanks - Fred

Hi Fred,

Ok ! Not my area of interest, but I understand the requirement.

Hi Sri,

Sure, that diagram could be redrawn with airplanes instead of automobiles. But,
consider also the case where the airplane is a mobile router that connects into a
home network provided by an aeronautical Internet service provider. Then, the
passenger devices are also mobile routers with their own home networks. That
would represent a single mobile-router-within-mobile-router nesting, but a
“nested NEMO” case nonetheless.

We also care about use cases outside of just commercial aviation. Unmanned Air
Systems, Unmanned Underwater Vehicles, MANETs, disaster relief networks,
search and rescue networks, space-based systems etc.

About tunnels within tunnels, we should be able to nest them to infinite levels
of recursion where each level sees at least a 1500 MTU. None of this 1460
reduced to 1420 reduced to 1380, etc. until we run out of space - there should
be a solid 1500 at every level with the ability to go bigger if the path MTU can
support it.

Thanks - Fred
