What is PENS

A joint EUROCONTROL / ANSP led initiative to provide a common IP based managed network service across

the European region Provide a efficient support to operational data and potentially

voice communications: - existing services - new requirements that are emerging from future Air Traffic

Management (ATM) concepts (incl SESAR).- In line with the SES-2 regulation (e.g. FMTP IR)

PENS contract placed in 2009 with a Telco provider (SITA) via a Call For Tender Procedure.

PENS will be used in the context of SESAR for the validation of the new services (VoIP, SWIM etc…)

PENS: the future of European aeronautical communications infrastructure

CFMU: • Existing network was already with SITA• Replacement of most desktops during PENS rollout• New service option (ANSP-owned PCs): Option 2

EAD: • Existing network was with AT&T• Migration completed within the PENS rollout• Fully operational since December 9th, 2010

ANSP Backbone: • No such network today, replacing bilateral lines• For data communications (FMTP, AMHS, radar, …)• Ready for service. Priority for 2011

Shared sites: • PENS Users sharing the infrastructure• cost optimization, alignment on highest service level

Conclusions

PENS is already in operation for EUROCONTROL services such as CFMU and EAD (IPv4 at present).

The PENS ANSP Backbone service is ready for activation to support ATM traffic (AMHS, FMTP, Surveillance, soon: VoIP (After validation)).

PENS is ready for SESAR verification and validation (SWIM). Activities related to network security, multicast (IPv4/6), VoIP validation

are on-going in the context of SESAR (P15.2.10).

Recommendations

ACP WGW is invited to: Note the PENS implementation in EUROPE. Note the current development activities (VoIP validation, Security, IPv6 global

addressing). Support the need for a global IP infrastructure in the near future to deploy

forthcoming ATM services: AMHS, SWIM, … Support the need for a global security policy. Note that the outcome of the PENS activities may provide input to future versions of

the Doc 9896 (“Manual for the ATN using IPS Standards and Protocols”) Invite ANC to task ACP for a globalisation of the IP connectivity (G/G), addressing

the security issues to provide a trustable SWIM/AMHS infrastructure.
