Abstract
The global aviation community has pursued the development and implementation of an industry-specific set of communications standards known as the aeronautical telecommunications network (ATN) for over 15 years. The ATN comprises application entities and communication services that allow ground, air-to-ground, and avionics data subnetworks to interoperate. This is achieved by using common interfaces, services, and protocols based on international standards. ATN has been specified to provide data communication services to air traffic service (ATS) providers and aircraft operating agencies, for air traffic services communication (ATSC), aeronautical operational control (AOC), aeronautical administrative communication (AAC) and aeronautical passenger communication (APC) types of communications traffic. The ATN model utilizes the TP4/CLNP stack as designed under the ISO environment. The predominant set of interoperability issues for aviation users has been created by the implementation of the ICAO ATN standards (a vertical set of standards useful only in the aviation community, and thus, creating in essence a closed network despite the use of open system ideas). Meanwhile, the rest of the world's industries, including those of the aviation's trading partners, have adopted IETF set of standards as the method to support data transport for all means of commerce, entertainment, etc. Numerous studies and research papers have provided a comparison of the ATN and the TCP/IP architectures. A result of this is the probable conclusion that operational benefits may be realizable to the aviation community it chooses to use Internet engineering task force (IETF) standards as the basis for a future communications, navigation and surveillance (CNS) infrastructure.

A result of this is the probable conclusion that operational benefits may be realizable to the aviation community it chooses to use Internet engineering task force (IETF) standards as the basis for a future communications, navigation and surveillance (CNS) infrastructure. Some future services may also be useful to the community. These services are additional benefits associated with the use of the transport control protocol and Internet protocol version 6 (TCP/IPv6). These protocols are available today. The services are not presently supported by the ATN's transport service protocols, the transport protocol class 4 and connection-less network protocol (TP4/CLNP). The paper also looks at a real time IPv6 initiative currently being explored by NASA GRC and EUROCONTROL for ways to migra- te existing aviation backbone infrastructure from X.25 to an IPv6 based network. In this regard, an IPv6 testbed is currently being implemented at Computer Networks and Software Inc. The intent of the testbed is to investigate performance issues of various aviation applications using an IPv6 based network. It should be borne in mind that this paper is premised on a scenario that sometime in the not too distant future, "All IP" aircraft are manufactured. In such a case, it is only natural to design architecture(s) that would enable the use of TCP/IP in the ATN environment.
