Major requirements Standards Interoperability Network Management Reliability Capacity and Performances What Prices and Risks 24/09/03 ATN 2003 (London)

Standards requirements Development methodologies Functional specifications Interoperability MIL-STD-498 RTCA DO178B (level C or D?) Eurocae ED-109 ICAO Doc 9705: “ATN SARPs” Edition 2 or 3? Additional PDRs Eurocae ED-110: “Interoperability Requirements Standards for ATN Baseline 1” 24/09/03 ATN 2003 (London)

Interoperability requirements Interconnection with other ATN BIS and ES Minimum Full compliance with ATN Standards Additional requirements Requesting product interoperability references Validation in the customer environment 24/09/03 ATN 2003 (London)

Network Management requirements Services Configuration Control and monitoring Integration in the existing Network Management system What Network Manager Agent? SNMP Other? 24/09/03 ATN 2003 (London)

Reliability requirements ATN router end-system Based on Network architecture one or several routers multiple paths ATN sub-network Operational Backup ATN Router Based on System architecture dual hardware/software configuration automatic failure recovery procedure front-end hardware 24/09/03 ATN 2003 (London)

Capacity & Performance requirements Requirements should be expressed in terms of Type of traffic Operational network and sub-networks architecture Supplier will transform them in terms of technical requirements IDRP route capacity Routing table entry Packet commuting capacity Hardware sizing 24/09/03 ATN 2003 (London)

Evolutivity requirements Hardware Up-to-date platform architecture (e.g. PC LINUX) Interface capability Software Supported ATN features Evolution from Ground to Air/Ground functions? New subnetworks (IP SNDCF) Optional companion tools 24/09/03 ATN 2003 (London)

Prices and risks How to optimize price and mitigate risks Product choice (COTS, development standards, number of sites, customer product references, hardware sizing...) Engineering service (project life-cycle vs COTS products, training, SAT...) Good support and maintenance contract (help-desk, on-site, tele-maintenance...) 24/09/03 ATN 2003 (London)

Conclusion Different products exist and are already in operational use But no “plug-and-play” solutions Thus, you must clearly identify Your requirements The target environment The envisaged engineering life-cycle … avoid “exotic” requirements 24/09/03 ATN 2003 (London)
