The NASA STI Program Office . . . in ProfileSince its founding, NASA has been dedicated tothe advancement of aeronautics and spacescience. The NASA Scientific and TechnicalInformation (STI) Program Office plays a key partin helping NASA maintain this important role. CONFERENCE PUBLICATION. Collectedpapers from scientific and technicalconferences, symposia, seminars, or othermeetings sponsored or cosponsored byNASA.The NASA STI Program Office is operated byLangley Research Center, the Lead Center forNASA’s scientific and technical information. TheNASA STI Program Office provides access to theNASA STI Database, the largest collection ofaeronautical and space science STI in the world.The Program Office is also NASA’s institutionalmechanism for disseminating the results of itsresearch and development activities. These resultsare published by NASA in the NASA STI ReportSeries, which includes the following report types: SPECIAL PUBLICATION. Scientific,technical, or historical information fromNASA programs, projects, and missions,often concerned with subjects havingsubstantial public interest. TECHNICAL TRANSLATION. Englishlanguage translations of foreign scientificand technical material pertinent to NASA’smission. TECHNICAL PUBLICATION. Reports ofcompleted research or a major significantphase of research that present the results ofNASA programs and include extensive dataor theoretical analysis. Includes compilationsof significant scientific and technical data andinformation deemed to be of continuingreference value. NASA’s counterpart of peerreviewed formal professional papers buthas less stringent limitations on manuscriptlength and extent of graphic presentations.TECHNICAL MEMORANDUM. Scientificand technical findings that are preliminary orof specialized interest, e.g., quick releasereports, working papers, and bibliographiesthat contain minimal annotation. Does notcontain extensive analysis.CONTRACTOR REPORT. Scientific andtechnical findings by NASA-sponsoredcontractors and grantees.Specialized services that complement the STIProgram Office’s diverse offerings includecreating custom thesauri, building customizeddata bases, organizing and publishing researchresults . . . even providing videos.For more information about the NASA STIProgram Office, see the following: Access the NASA STI Program Home Pageat http://www.sti.nasa.gov E-mail your question via the Internet tohelp@sti.nasa.gov Fax your question to the NASA AccessHelp Desk at 301–621–0134 Telephone the NASA Access Help Desk at301–621–0390 Write to:NASA Access Help DeskNASA Center for AeroSpace Information7121 Standard DriveHanover, MD 21076

ABSTRACT (Maximum 200 words)Aeronautical Telecommunication Network (ATN) has been developed by the International Civil Aviation Organization tointegrate Air-Ground and Ground-Ground data communication for aeronautical applications into a single network servingAir Traffic Control and Aeronautical Operational Communications. To carry time critical information required foraeronautical applications, ATN provides different Quality of Services (QoS) to applications. ATN has therefore, beendesigned as a standalone network which implies building an expensive separate network for ATN. However, the cost ofoperating ATN can be reduced if it can be run over a public network such as the Internet. Although the current Internetdoes not provide QoS, the next generation Internet is expected to provide QoS to applications. The objective of thispaper is to investigate the possibility of providing QoS to ATN applications when it is run over the next generationInternet. Differentiated Services (DiffServ), one of the protocols proposed for the next generation Internet, will allownetwork service providers to offer different QoS to customers. Our results show that it is possible to provide QoS to ATNapplications when they run over a DiffServ backbone.14. SUBJECT TERMS15. NUMBER OF PAGES24Protocol; Internet16. PRICE CODEA0317.
