A simplified aeronautical telecommunication network (ATN) avionics architecture

Abstract

It would seem to be advantageous for countries that desire to provide air traffic services via mobile networking to profile a set of ATN options that allow aircraft to operate without an ATN router. Such a profile should also allow for simplification of the OSI transport layer by substituting a connectionless transport for a connection-oriented transport. These changes would be applicable only to aircraft that have one air/ground data link installed and consequently do not need the power of an ATN router in the aircraft. A large majority of such aircraft would be start-up commercial carriers and general aviation aircraft.
