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.

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.

Messaging

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.
