Background
• While we were setting up the registry, the technology moved forward
• New security standard DNSSec is close to deployment
– designed to protect against many known DNS threats
– several test beds already operational
– security framework for XML (SAML) already assumes deployment of DNSSec
• DNS is used as an online database for different digital identifiers
– telephone industry is merging telephone numbers with domain names
– RFID industry is implementing the same DNS based technology
• This presentation explains how our community can benefit

Safe transition to Internet style-services
• Our industry is moving towards “always on” Internet style services
– More than a change of protocol
– Supply of network services becomes a commodity
– New technology requires new approaches
• Safe and effective Internet use depends on or benefits from
– Automatic alternate routings (one ISP fails, traffic routes through another)
– Dynamic construction of virtual circuits (in or out of secure tunnels)
– Abstraction of “host” from “connection point” (host’s name remains the same, when
supplier or router used changes)
– Authentication of connections and end to end messages is critical

Abstraction of “host” from “connection point”
In X.25 style network, everyone used
one hardened network, each connection
also served as an authentication and
mechanism and for addressing

At the time of Internet-style
communications, network service
supply is a commodity, and it may be
cheaper to use multiple suppliers.
Authentication of and addressing to
many partners is still difficult.

For safe use of Internet addressing
independent on connection points
and authentication are critical.
DNS is key

.aero as an Enabler
• DNS technology is key to many new approaches
– Logical addressing through a name space is needed to allow redundant
connections and routing through multiple suppliers and rapid fall-over to backup
systems
– Authentication of DNS responses is critical (via DNSSec)
• .aero is controlled by the industry
– Ability to deploy new technologies on industry schedule, without national or
commercial-domain constraints
– Brand already developed and distinct from pre-Internet technologies
– DNS for key/certificate storage and delivery

Examples
•
Baggage mediation
–
–
•
Location of reservation systems
–
–
•
All connections to res systems could be based on domain names
No need to reconfigure corresponding systems when IP address changes (now 3-4 weeks
needed to change)
International e-ticket system could use the technology
–
–
•
Authoritative pointers to airline systems worldwide (baggage mgmt, DCS)
Integration with RFID technology for anytime anywhere baggage information
Big airlines can do it bilaterally, but experience so far has involved many “kinks”
Global use requires global standards and a transaction mediator – .aero platform is owned by
the community
Possibly collaborative decision making
–
Using DNS eliminates the need for a maintaining a central database

The Industry Perspective
•
•

•
•
•
•
Reduced networking costs
Better integration of inter airline traffic with intra-airline systems
Better integration of inter airport traffic with intra-airport systems
Better services for “alliance” models
Easier communications with and authentication of 3rd parties
Automatic fall-over to alternate systems and better disaster recovery
Fewer customer-perceived differences between service capabilities of “large”
and “small” entities
Faster responses of entire industry to changes
Reduced dependency on short, cryptic messages, reducing personnel costs

Consultative process
• Suggestions in this presentation are based on our consultations with
renowned Internet experts
– Dr. Brian Reid from Internet Software Corporation
– Dr. John Klensin, independent consultant former chair of IAB, ICANN director and
liaison between IAN and ICANN
– Dr. Paul Mockapetris, the inventor of DNS
• Some concepts were informally consulted with airlines and airports
• Formal consultation to follow during a workshop in November

Summary
• .aero as an integral part of air transport comms infrastructure
• Industry system of digital identifiers for Internet-style communications
• Means to use Internet effectively and safely
• Now must focus on specific applications to move forward
