13. Network Management and the ATN (1 of 3) • Current Industry Situation: • Neither industry nor ICAO standards baseline yet available • But, operational need identified for management of initially deployed ATN, based on telecommunication industry experience • ACI’s approach to problem… • Meet near-term needs (1Q 2000) for managed prototype ATN routers, offering ProATN-compatible NM products • Meet mid-term needs (4Q 2000) for managed operational ATN routers, offering RRI-compatible NM products • Address longer-term needs (2001+) for managed ATN ground-based and airborne systems by supporting government/industry requirements definition process ACI/GM/3011/1.0

14. Network Management and the ATN (2 of 3) • Phase 1a (1998) Completed • Phase 1 MIB produced as result of industry collaboration • Phase 1 MIB Features & Functions • Fault, Performance, Security, Configuration & Accounting • Functionality consistent with ProATN & RRI/ASE capabilities • Phase 1b (1999) In Progress • NMA-1P: ATN Prototype Network Management Agent • Developed for & integrated with ProATN Router by ACI • Methodology consistent with that of ProATN • Managed via NMS-1P, developed by ProATN Consortium • Validate network management concept in ProATN context ACI/GM/3011/1.0

Network Management and the ATN (3 of 3) • Phase 2 (2000+) Planning Stage • Develop Phase 2 concept of operations (CONOPS) • Incorporate operational safety assessment • Define design assurance level consistent with application • Define architectures (air/ground) based on CONOPS • Upgrade NMA-1P to interface with RRI • Develop Phase 2 air & ground components • Network Management Agents • Managers ACI/GM/3011/1.0

16. Software Quality & ATNConsiderations (1 of 2) • ATN architecture created for support of safety-critical ATS and AOC applications • Controller/pilot communications (ATS), e.g. clearances • Controller/controller communications (ATS), e.g. handoff • Airline dispatch/pilot communications (AOC), e.g. re-routing • How? • Integrity Assurance via protocol design • “what is received is what was sent” • Enhanced Availability via routing architecture • “information transferred end-to-end in a timely manner” ACI/GM/3011/1.0

17. Software Quality & ATNConsiderations (2 of 2) • Safety-critical application of ATN protocols demands software design & quality assurance consistent with “Essential” systems • Rationale: undetected integrity/availability failures may cause unacceptable dispatch/controller/pilot work-load • RTCA DO-178B provides software development guidelines for Level C, to meet “Essential” systems requirements • ACI’s approach to problem… • To ensure ATN software mission-readiness…all ACI RRI/ASE software conforms to DO178B Level C guidelines ACI/GM/3011/1.0

18. Software Quality & ATNResults (1 of 2) • Result: software products meet requirements • Airborne systems require DO-178B Level C software • ATS ground systems recommend or require DO-178B Level C software • AOC ground systems require mission-critical treatment; DO-178B Level C meets this requirement • Result: reduced lifecycle cost to user • Formalized nature of DO-178B Level C development process leads to high overall product quality • Process facilitates change management & lifecycle support ACI/GM/3011/1.0

19. Software Quality & ATNResults (2 of 2) • Result: comprehensive verification & validation • Production of required artifacts demonstrates compliance and supports users of software products • Full traceability of functions to design, to code, and to test • Full functional test coverage • Verifies that all functions have been tested • Full structural test coverage • Verifies that all code is executed • Result: reduced end-to-end integration risk • Development of airborne and ground-based software to common standards reduces interoperability risk ACI/GM/3011/1.0

20. In summary… • ACI has been working since 1997 in support of global ATN deployment for the new millennium • To this end, ACI is developing a line of lifecycle supported ATN software, along with integrated software packages and turnkey ground systems • ACI continues to work aggressively with ATN stakeholders to address ATN deployment challenges, including issues of network management, certification, and design level assurance standardization ACI/GM/3011/1.0
