Operational Messaging Introduction
 Type B is used by virtually all SITA customers. It supports
message based communications between all our Type B
customers.
 Type B supports the daily use of reservation systems,
inventory systems, cargo systems distribution of flight plans to
Air Navigation Service providers, sending of Advance
Passenger Information to national border control agencies etc.
 The complexity of airline operations coupled with increased
customer expectations has made development and
implementation of reliable IT, communication with partners
critical to the mission of most ATI companies.

ACARS XML
Freeform SPEC 2000 XML (ATA)
 Electronic Data Interchange (EDI) covers the exchange of electronic documents of
an operational or commercial nature between computer applications.
 The applications can be operated by the same or by different companies.
 The term EDI specifically covers the rigorously standardized structure, format and
coding of content of these electronic documents. Without this the applications would
not be able to process the exchanged transactions correctly.
 Its related domains are:
– Coding applications for writing/reading exchanged documents
– Addressing
– Transmission, often using a third party service to serve the many-to-many
environment
– Underlying commercial agreements
 Type B may be seen as an EDI system.
– Standards are defined by the industry, and managed by IATA (e.g AirIMP)
– Message writing/reading is done by the relevant ATI application
– Addressing conforms to the Type B addressing scheme (e.g LHRRVXS)
– Transmission is via the SITA Mega Switches in Atlanta and Singapore
– Many commercial agreements are in place
 The ATI’s evolution means that SITA offers support for a range of different EDI standards
(IATA standards, other ATI standards and national and international standards.)

ATA/IATA Reservations Interline Message Procedures - Passenger (AIRIMP)
 The sole reference source for the communications standards for the handling
of Passenger Reservations Interline Messages.
 The AIRIMP standards are used in transactions between Travel Agency and
Airline/GDS systems and by Airline to Airline systems.
 Airline Res to GDS, websites and other airlines – eg AVS Airline
output to update the Availability Status of their inventory
 Airline Inventory System DCS – eg PNL Passenger Name List
 DCS to Border Authority – eg UNA Advanced Passenger
Information
 IATA Reservations Committee (RESCOM)
 Responsible for the development of transmission of reservations services
for use by customers and agents.
 PADIS: Passenger and Airport Data Interchange Standards.
 Functional business requirements for application level messages based
on UN/EDIFACT inter-active transaction standards.
 This is not related to Type B Messaging.
 68% of messages have a message type indicator (SMI) that is defined in the
IATA standard
 32% of the messages are developed between partners, and have grown to
9000 additional (non)standard message indicators.

ATI Messaging Products - Example: MVT – Movement
Message
 The exact operation of the schedule is reported via Movement Messages
 They are reported to the next station down the route (“down line”)
 AD - actual departure of aircraft
 AA - actual arrival of an aircraft
 ED - Estimated departure of an aircraft
 NI - Next info (update)
 RR - return to ramp of an aircraft (with implies problem and further delay)
 Simultaneously related messages may be sent:
 Passenger Transfer Message (PTM)
 Passenger Services can re-book those who will miss connections
 Statistical Load Summary (SLS) to Accounting.

 The ACARS standard supports message transfer between airborne users and
ground users via air-ground links.
 The format and protocol for the air-ground link is specified in AEEC 618
specification.
 The format for the ground-ground link is specified in AEEC 620 specification.
 The DataLink Service Provider (such as SITA) does the conversion between the
above two formats.
 Air-Ground messages are used by Air Traffic Control and Airline Operations during
all flight phases.

ATI Messaging Products - EDI Standard: XML(ATA)
ANSI X.12
CargoIMP
AIRIMP EDIFACT
ACARS XML
 Codification of SPEC 2000 Commands into XML began in June 2000
 Type B based SPEC 2000 Commands were easily converted to XML
since SPEC Text Element Identifiers (TEI) could become XML Data Tag
Descriptors (DTD) The TEI was logically consistent with DTD definition
 The following SPEC 2000 Chapters have been published in XML
– Chapter 2 Procurement Planning
– Chapter 3 Order Administration
– Chapter 4 Invoicing
– Chapter 11 Reliability Data Exchange
– Chapter 16 Electronic Product and Part Regulatory Documentation
 In 2006 use of DTD was replaced by WSC3 XML schema
representations
 SPEC 2000 XML is now aligned with leading information exchange
framework standards that support schemas including:
– Web Services Description Language (WSDL)
– Simple Object Access Protocol (SOAP)
– Business Process Execution Language (BPEL)

ATI Messaging Products - EDI Standard: ANSI ASC
X.12
ANSI X.12
CargoIMP
AIRIMP EDIFACT
ACARS XML
 ANSI ASC X.12 is the official designation of the U.S. national standards body for
the development and maintenance of EDI standards.
 It stands for "American National Standards Institute Accredited Standards
Committee X12",
 ANSI ASC X.12:
– Was founded in 1979
– Is focused on health care, insurance, government, transportation, finance.
– Has sponsored more than 315 X12-based EDI standards (all industries)
– Is developing X.12 XML messages
– Has a membership of 3,000+ standards experts, representing over 350
companies.
– SITA became involved in the 1990’s, while developing its EDI Clearing
House for the exchange of business documents between airlines and their
suppliers.
 The issue was that NAM airlines wished to remain on the standard that they were
using for general domestic supply.
 The main use of X.12 in SITA is in the SPEC2000-X12 Conversion Service.

ATI Messaging Products - EDI Standard: EDIFACT
ANSI X.12
CargoIMP
AIRIMP EDIFACT
ACARS XML
 United Nations/Electronic Data Interchange For Administration,
Commerce, and Transport (UN/EDIFACT) is the international EDI
standards developed under an United Nations initiative.
– It is the dominant standard outside NAM
– Airlines exchange a large volume of Inter-active EDIFACT over direct links
– EDIFACT is emerging as the standard for APIS (Advanced Passenger
Information)
 The EDIFACT standard provides
– A set of syntax rules to structure data,
– An interactive exchange protocol (I-EDI),
– Standard messages which allow multi-country and multi-industry exchange.
 There is tension between XML and EDIFACT.
– An equivalent XML message has a larger file size than an EDIFACT message
(Ratio of up to 10:1)
– More tools exist to work with XML data than with EDIFACT.
– An advantage of EDIFACT is the availability of agreed message-contents, which
XML must leverage to develop its own similar agreed contents.
– Europe has a large EDIFACT installed base because it adopted the technology
early.
– The Asian region adopted B2B models and is moving to XML standards.

 As other technology communities grew, they sought to exchange with the Type B Community
 The underlying switching environment was developed in X.400
 In the diagram:
– The Type B Gateway server is mapping between Type B and X.400 message standards
– The SMTP Gateway server is mapping between IP and X.400 message standards.
 Mapping for IATA EDI standards will need to be configured on the Type B Gateway.
 Limitations on Type B has an effect, eg:
– The max character length is 3000ch, so multiple messages might go out to Type B
– There is an overall size limitation of 64k for messages (2Mb for documents) to Type B
– All messages will go to Type B with the QN priority.

 This is the core of the SITA Type X Service.
 Type X-Type B gateway, that maps Type B and Type X message structures
(i.e. address mapping, priority mapping etc.).
 Payload or message content conversion that allows conversion of standard
or customized formats conversion to/from XML.
 Powerful proposition for new Type X implementation, because their
business partners will be using Type B.

 The Simple Mail Transfer Protocol is part of the TCP/IP suite, defined by RFC’s
822 and 821. In the OSI 7 layer model SMTP sits at layers 5, 6 and 7.
 A diagram is shown in the preceding slide on the Type B Gateway
 External access to the SMTP Gateway Service is provided by a SITA IP VPN
connection.
 The SMTP Gateway:
– enables a degree of integration between standard IP messaging and
Type B messaging
– is designed for a medium volumes of messages
– was not designed to convert any of the industry’s operational messaging
(which must be specifically customised on the Type B gateway)
 SMTP mailboxes (i.e a “Hotmail” type of mailbox) available.
 The SMPT Gateway has been used by Business Direct to create a low cost
mailbox solution to Type B by mapping the SMTP address to Type B addresses.

Note:
 Currently SMTP to Type B traffic is billed as X.400 traffic. Product Management state that they are
“working to change this, so that this traffic will be billed as Type B traffic”.
 Check with John Picot/Andrew Coleman if the SMTP Gateway is to be sold as part of a solution.

 The airline community requires SITA to interconnect the SITA
Messaging switch via a gateway to the ARINC network
 This allows users, terminals and systems of each network to
communicate with each other.
 Customers pay more for traffic via the gateway than for traffic
that uses just one provider because the customer will be
charged by both SITA & ARINC
 Gateways operate under a contract agreed in 2005.

 Each Civil Aviation Authority (CAA) runs its own network,
compliant with the AFTN specification.
 These national networks are inter-connected.
 Used to exchange information to ensure safety of air
navigation and to control air traffic between different
geographic areas or states.
 These integrated AFTNs:
– Uses store and forward messaging
– Follow a standard for message content
– Uses a different addressing standard to Type B
– Normally uses low-speed circuits
– Medium-speed circuits connect major regions.
 SITA connects to 50 AFTNs
AMHS - Aeronautical Message Handling Services – is the ICAO defined replacement for AFTN.
Implementation of the protocol has been extremely slow with very few countries actually running an AMHS
based network.
SITA has been discussing AMHS gateway functions with a few countries but there is no commercially valid
demand at the moment (2009)

 AFTN Gateway in Singapore: (NTS)
– The AFTN Gateway in Singapore does not act as an AFTN
interconnection.
– It maps between AFTN and Type B addresses in both directions
 It is necessary for each CAA to connect to the SITA Network
– Circuits have to be configured to accept input in AFTN format.
– Today, CAAs in over 50 countries connect to the SITA Network
through over 200 specially configured circuits.
 SITA’s Type B Messaging Service supports two distinct flows of
traffic involving AFTN users:
– Traffic between CAAs - from one AFTN user in Country A to AFTN
user in Country B.
– Traffic between CAAs and Airline Type B users
 SITA Type B users sending messages to an AFTN user can
either:
– Generate Type B messages (SITA translates the Type B
addresses to AFTN addresses), or
– Generate AFTN messages, and add a Type B header with a SITA
processing address
 (SITA then removes the Type B header and delivers the AFTN message).
 The AFTN Gateway service is not always bi-directional. Take
care!

ATI Messaging Products - Transport: In use, but at
end of life
 AX.25 and P1X24 are still used by
100 customer connections.
 These protocols are old,
expensive and entering end of life.
 SITA recommends that customers
migrate from these connections.
 SITA’s support costs are causing
these connection prices to
increase.
 The replacement solution is:
– MATIP or MQ
– IPVPN.
 Asynchronous connections are
closer to end of life.
 Local PTT planning to close.
 This is already affecting some
AFTN connections.
