AMHS Workshop 17Federal AviationAdministrationApril 2012
NADIN-II Decommissioning StrategySLC NEMC Move (completed)
– SLC node consolidation into the ZLC ARTCC node
Phase 1• Reduce the network from 26 to 9 core nodes that support key
systems (e.g. Oceanic) to give additional time to formulate a transition plans
– NAS users to move to TCP/IP; External users to move to CMHP– International users to consolidate to ATL/SLC or move to AMHS– Move user connections/circuits to core nodes
Phase 2• Concentrate residual X.25 links (e.g. International AFTN)
on Atlanta (ATL) and Salt Lake City (SLC/ZLC)– Move remaining user connections to ATL and SLC/ZLCg
Phase 3• Provide X.25 to CMHP conversion for remaining X.25 traffic

NADIN-II – FY 12 Goals (Dec 2011)
– ARINC IP transition for NADIN and TDLS – schedule Mar-Jul 2012
– Concentrate international AFTN at ATL and SLC – 72% completep
– ADAS rehost deployment - OMO data distribution via WMSCR
• Scheduled April-June 2012
– NAIMES (AISR, USNS, FS21) redeploymentMoving from Herndon VA to OKC (complete)
• Transition OKC from X.25 to IP (Apr-Jun 2012)( p )• Establish disaster backup at Herndon (CY13Q1 Herndon)
– ATOP/ DOTS/ FDP2000 IP solution for ARINC/ SITA1370 114 (1/2012) now gives clear path forward• 1370.114 (1/2012) now gives clear path forward
– Reduce the number of nodes to Phase1 (Core)
