Security Disclaimer:

   This document fails to adequately address security concerns.  The
   protocol itself does not include any security mechanisms.  The
   document notes that traffic can be authenticated based on external
   mechanisms that use static identifiers or what are apparently clear-
   text passwords, neither of which provide sound security.  The
   document notes in general terms that traffic can be secured using
   IPSEC, but leaves this form of sound security strictly optional.


   This memo specifies a protocol for the encapsulation of the airline
   specific protocol over IP.

1. Introduction

   The airline community has been using a worldwide data network for
   over 40 years, with two main types of traffic:

    Transactional traffic

      This is used typically for communication between an airline office
      or travel agency and a central computer system for seat
      reservations and ticket issuing. A dumb terminal or a PC accesses
      the central system (IBM or UNISYS) through a data network.

      This traffic is also called TYPE A and is based on real-time
      query/response with limited protection, high priority and can be
      discarded. The user can access only one predetermined central
      computer system. In case of no response (data loss), the user can
      duplicate the request.


      This is an e-mail application where real-time is not needed.
      However a high level of protection is required. The addressing
      scheme uses an international format defined by IATA and contains
      the city and airline codes.

      This traffic is also called TYPE B and is transmitted with a high
      level of protection, multi-addressing and 4 levels of priority.

   The detailed formats for TYPE A and TYPE B messages are defined in
   the IATA standards.
