Objectives
In the context of aeronautical air-ground mobile data communications, the project is concerned with the development of network functions which enable interworking between legacy ATN/OSI and future ATN/IPS networks.
The context for the design of the Interworking Functions is Airtel’s existing ATN/OSI code base.
The objectives of the Interworking in the ATN study are as follows:
- To specify aeronautical network interworking functions and implement a prototype,
- To provide a concept of verification of the interworking functions to support the future overall verification and validation of the integrated communication system,
- To verify the defined interworking functions according to the defined concept.
Challenges
The focus of the project is the implementation in software of a prototype of the ICAO IPS DSI function. The IPS DSI (defined in ICAO Doc 9896) provides interoperability between legacy ATN Air Traffic Control applications (designed around ATN/OSI) and future IPv6 networks. The IPS DSI implements a mapping of ATN/OSI primitives and protocols to IPv6 protocols and data structures.
In addition to the software implementation, the second achievement of the project was the conception, development and implementation of an ATN Interworking Demonstrator, using an ATS Function (CPDLC), to validate the ATN/IPS Function in an End-User environment. This Demonstrator was an Mobile IPv6 Test Bed.
