The heterogeneity of the global aggregated traffic and a seamless inter-operation of such systems with existing ground networks seem to indicate a need for an IP-based aeronautical network. A new generation of IP-based data links using satellite broadband communications is expected to merge. Current aeronautical networking standards are base on the ISO OSI protocol suite and are referred to by the International Civil Aviation Organization (ICAO) as Aeronautical Telecommunications Network ATN/OSI. But ICAO has also defined an ATN/IPS based on the Internet Protocol Suite (IPS) to enable the use of Commercial-Off-The-Shelf (COTS) technologies [6], mainly to reduce the overall system development and maintenance costs.
