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

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

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

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”

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

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

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

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

ACI/GM/3011/1.0

In summary…

ACI has been working since 1997 in support of global ATN deployment for the new millenniumTo this end, ACI is developing a line of lifecycle supported ATN software, along with integrated software packages and turnkey ground systemsACI continues to work aggressively with ATN stakeholders to address ATN deployment challenges, including issues of network management, certification, and design level assurance standardization
