14. ACI/GM/3011/1.0 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 ACIs 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

15. ACI/GM/3011/1.0 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

16. 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

17. ACI/GM/3011/1.0 Software Quality & ATN Considerations (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

18. ACI/GM/3011/1.0 Software Quality & ATN Considerations (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 ACIs approach to problem… To ensure ATN software mission-readiness…all ACI RRI/ASE software conforms to DO178B Level C guidelines

19. ACI/GM/3011/1.0 Software Quality & ATN Results (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

20. ACI/GM/3011/1.0 Software Quality & ATN Results (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

21. ACI/GM/3011/1.0 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
