7. 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

8. 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)

9. 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

ATN 2003 (London)

10. 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...)

ATN 2003 (London)

11. 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
