ECAC TCP/IP Strategy (1)

• Applicable to ATM Ground/Ground communication
• The Problem
• All international ATC data exchange applications
  such as OLDI, make use of X.25 technology
• Key manufacturers have stoppedselling X.25
  equipment and will cease support after 2005
• The Solution is IP
• IP is omnipresent and mature
• IPv4 is implemented in States different
  approaches
• IP version 6 is supported by the European
  Commission (PR 29/01/02)

4
ECAC TCP/IP Strategy (2)

• IP version 6 for international data exchange
• Address translation for existing IPv4 islands
• States are encouraged to migrate from IPv4 to
  IPv6
• Institutional Issues for IP service provision
• ECIP COM 09 migration from X25 to IP is under
  development
• Strategy To implement the transition from
  legacy CONS to high QoS COTS-based IP technology
  to support current and future application
  requirements for ground environment.

5
iPAX Task Force

• IPAX Task Force established to
• modify aeronautical standards for the exchange of
  ATM/CNS data
• migration from X.25 to TCP/IP protocol suite
• focus on ground data communications
• WAN Trials
• 14 European sites connected via IPv6
• IP security (IPsec and firewalls)
• OLDI, ASTERIX, AMHS over TCP/IP data exchange
• www.eurocontrol.int/ipax

Flight Data Exchange - OLDI (1)
7
Flight Data Exchange (2)

• FDE/ICD Part 1 implemented in 80 Civil/Mil
  centres based on X25
• FDE/ICD Part 2 supports TCP / IP
• No change to the OLDI application
• Validation by iPAX
• Procedure for publication as standard started
• ECIP COM-04 Time scale 1/2004 -
  12/2007www.eurocontrol.int/ecip/level2/com04.pdf
• OLDI is a subset of AIDC

Radar Data Distribution (1)

• RADNET - Germany / Benelux (4 States/EUROCONTROL)
  
• RENAR - France
• UK-RADNET - United Kingdom
• CADIN - Czech Republic
• REDAN - Spain
• SACON - Slovak Republic
• ACN - Austria
• CANDI
• etc.

Radar Data Distribution (3)

• Todays radar network based on X.25 (e.g. RADNET)
• Migration to TCP/IP
• International Impact 30 sensors 60 radar
  systems
• for RMCDE IPv4 multicast profile for
  surveillance data distribution defined

11
Message Handling (1)

• AFTN/CIDIN will be replaced by AMHS
• AMHS in ECAC will use TCP / IP
• An AMHS/IP specification is under development and
  submitted to ICAO/ACP/WGN
• Communication between AMHS/IP and AMHS/ATN or
  AFTN systems will be ensured via double stacks
• The ECG (Eatm Communications gateway) implements
  the AFTN/AMHS gateway as specified in Doc 9705
  and provides dual stack underlying network (ATN
  and TCP/IP)
• ECIP COM-05 www.eurocontrol.int/ecip/level2/com05
  .pdf
• Migration of AMHS to an IP COTS-based messaging
  (long term)

ECAC ATN Strategy (1)

• The ATN internet is the strategic solution to
  support Air - Ground applications( For G/G
  applications IP is the strategic solution).
• ECIP ATC06 Implement ATC A/G Data Link Services
  - www.eurocontrol.int/ecip/level2/atc06.pdf6/2003
  - 12/2007 ( Link2000 Programme)
• The IP SNDCF allows COTS IP Networks to carry ATN
  A/G Traffic ( e.g. CPDLC messages)
• Airborne IP (in the cabin) can coexist with ATN
  (in the cockpit)

15
ECAC ATN Strategy (2)

• Co-ordinating the implementation of en-route
  CPDLC (ACM, ACL, AMC, DLIC) over ATN/VDL2 by
  2007.
• Providing a migration path for legacy DCL and
  D-ATIS data link services to ATN/VDL2.
