Implementation strategy

• Def. ATN infrastructure to support SCALA plans
  based on ACCESS results
• choice of router hardware platform
• addressing plan
• dependability issues
• systems management security solutions
• network dimensioning
• Implementation/Validation of Package 2 SARPS
• Eurocontrol Link2000 Programme

Broadmap of french ATN

• Data-link servers (front-end to application
  servers) in ACC with an ES ATN stack
• Ground-ground Subnetworks -RENAR for WAN
  interconnected with others Networks belonging to
  EAN -Ethernet and/or FDDI for LAN
• Air-Ground Subnetworks -VDL2 stations operated
  by CSPs -AMSS after
• BIS ATN A/G and G/G

10
Pending questions

• VDL scenario A/G BIS ATN belonging to DGAC or
  CSPs ? (G/G BIS belonging to DGAC)
• AOC trafic supported by infrastructure link with
  VDL scenario
• Performances
• Security
• Sites equiped with BIS or IS Router
• Reutilisation of current ISO routers

CONCLUSIONS

• The technology is now ready for implementing ATN
  on ground side
• The results of ATNSI project will be decisive on
  airborne side
• ATN can be operational before 2005 if ATSOs and
  Airlines say alltogether  GO
