Hi Fred, Ok ! Not my area of interest, but I understand the requirement.
Regards Sri From: <Templin>, Fred L <[email protected]<mailto:[email protected]>> Date: Wednesday, September 24, 2014 3:59 PM To: Sri Gundavelli <[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: RE: Signaling Message Fragmentation 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
