We present an integrated telemetry data link and network architecture system solution, developed by Mayflower for the Air Force, AFFTC, Edwards AFB, CA, based on third generation UMTS cellular standards. The data link, called COTS Affordable Data Link System (CADLS), accommodates high mobility user applications typical of tactical fighter aircraft. The data network, called Telemetry/TSPI Data Network (TDN), uses enhancements such as a multi-tiered network protocol structure to provide flexible IP-based transport, work with multiple air interface protocols, accommodate test platform mobility, and integrate seamlessly with unified infrastructure such as Test and Training Enabling Architecture (TENA). The end-to-end CADLS/TDN datalink network system, described in this paper, is a 2-way, asymmetric IP-based wireless network system, and as such it is a potential candidate technology to support the DoD CETIP integrated Network Enhanced Telemetry (iNET) project. The integrated CADLS/TDN system is at an advanced stage of prototype development. We present the integrated CADLS/TDN system architecture, its features and capabilities, and the laboratory prototype developed under the Air Force program.
The intent of this paper is to provide a comparison between the anticipated performance of the interim AEEC ARINC Specification 622lACARSlSATCOM data link and its successor, the Aeronautical Telecommunications Network (ATN). Performance parameters studied include capacity, end-to-end transit delay and throughput with a focus on handling of safety data. Computer models were used to simulate each system and collect all performance data. In order to make a valid comparison, a common traffic model was employed and common configuration was chosen for the AMSS which is the airlground satellite subnetwork utilized by both systems. This paper compares the anticipated performance of the two systems and highlights the advantages of the ATN. It is evident from the results presented herein that ATN offers higher capacity, better transit delay performance and superior throughput performance compared to the interim data link, and the gains from ATN are most pronounced for longer data message lengths. 0-7803-3050-1/95 $4.00 0 1995 IEEE
