Strong Air Traffic Growth in Europe

• Air Traffic in Europe will double within the next
  20 years (2000 -gt2020)

ATC Communications in the Air

• ATC Communications requires Quality Of Service
• Largely based on analogue voice communications
  over VHF and HF (oceanic)
• Requires global co-ordination led by the
  International Civil Aviation Organisation (ICAO)
• Data link services have started to be deployed

Status in the Air

• CPDLC makes use use of ICAO Aeronautical
  Telecommunication Network (OSI) over a VHF data
  link (VDL2)
• Narrowband
• Independent of other on-board data communications
  services such as
• Passengers (satcom)
• Airline Communications (ACARS)
• Several on-going intiatives
• Investigations into wide-band technologies for
  air/ground ATC communications
• Continuous trials worldwideUMTS, US Coast Guard,
  NASA,
• ICAO considering to define new IPv6-based
  standards for the ATN
• Slow process avionics certification, retro-fit
  costs, etc.

On the Ground mixed X.25 and IPv4

• International Data
• ATC over X.25
• Application-specific IP VPN
• National Services
• Internal IP/X25 applications
• X25 Links to SITA/ARINC
• Management, etc..

8
IPAX Task Force Trials (2001-2004)

• WAN trials to support RD activities to plan
  migration from X.25 to IP
• 12 European ANSPs, 22 logical interconnections
• various lower media (VPN, Internet, LL, ISDN, MW)
• 14 European sites NASA connected via IPv6
• Directory services (DNS)
• IP security (IPsec and firewalls)
• X.25 over TCP/IP
• ATC Applications

Our Rationale for IPv6

• Re-numbering is not acceptable to overcome IPv4
  address conflict
• Multiple layers of IPv4 NAT over-complicate the
  architecture and difficulty to find a common
  address pool for a double NAT environment between
  conflicting routed domains
• End-systems that require international access
  should be dual-stacked (IPv6 is defined as the
  standard network protocol to which all
  applications should converge to ensure
  interoperability)
• Trials prove that in our context, international
  Multicast, VoIP and MobileIP are best supported
  over IPv6
• Trials prove NAT-PT is compatible with our
  unicast applications, so even if we have to do
  NAT why not NAT to IPv6 (NAT-PT) ?

10
Other Motivations for IPv6

• Deployment Issues
• IPv6 does provide a valid long-term architecture
  (due to deployment cycles)
• Trials prove that we can handle a transition
  phase over a long period
• Minimise exposure to IPv6 to reduce market
  risks
• Own a /32 to ensure telecom provider IP address
  independence
• IPv6 is not vendor dependent
• Global/Regional Issues
• Future IP for air/ground communications is likely
  to be IPv6 based
• EUROCAE WG67 is investigating the use of VoIP for
  ATC (likely to be IPv6)
• IPv6 pick-up rate

Deployment Actions

• 2005-2009
• X25 -gt IP migration has already started leading
  to a mixed X.25/IPv4/IPv6 environment
• PEN Project still in a scope definition phase
• 2006 Pan-European Network Call for Interest
• 2007 Pan-European Network Call for Tender
• 2008 Deployment of Pan-European Network and
  operational evaluation/validation
• Summer 2008 initial operations
• 2010 Application and Service extension
• Voice, A/G applications, International Multicast,
  .

12
What is PEN

• Pan European IP network service of the ATM sector
  which will ultimately carry all data and voice
  applications
• A procured multi-protocol managed service
  (supporting both IPv4 and IPv6) to initially
  provide (as a minimum) the data backbone to
  interconnect existing IP networks
• Overtime to be scaled to include multicast and
  voice at a later stage

Ground Applications IPv6

• EU Single European Sky Implementing Rule on
  Flight Message Transfer Protocol (FMTP)
• Forthcoming Rule mandating a EUROCONTROL FMTP
  Specification (IPv6)
• Some stakeholders ready for operations
• EUROCONTROL Introduce both IPv4 and IPv6 in
  communications and surveillance products under
  its remit
• Worldwide ICAO Aeronautical Communications Panel
  (ACP)
• Drafting of new networking standards and
  recommendations based on IPv6
• First operational deployment of Air Traffic
  Services Message Handling System (AMHS) based on
  the outcome of the iPAX trials making use of IPv6
