Achieving QoS for Aeronautical Telecommunication Networks over Differentiated Services
ABSTRACT
Aeronautical Telecommunication Network (ATN) has been developed by the International Civil Aviation Organization to
integrate Air-Ground and Ground-Ground data communication for aeronautical applications into a single network serving Air
Traffic Control and Aeronautical Operational Communications. To carry time critical information required for aeronautical
applications, ATN provides different Quality of Services (QoS) to applications. ATN has therefore, been designed as a
standalone network which implies building an expensive separate network for ATN. However, the cost of operating ATN can
be reduced if it can be run over a public network such as the Internet. Although the current Internet does not provide QoS,
the next generation Internet is expected to provide QoS to applications. The objective of this paper is to investigate the
possibility of providing QoS to ATN applications when it is run over the next generation Internet. Differentiated Services
(DiffServ), one of the protocols proposed for the next generation Internet, will allow network service providers to offer
different QoS to customers. Our results show that it is possible to provide QoS to ATN applications when they run over a
DiffServ backbone.
