Since the traditional technologies permanently reserve the bandwidth of the maximum data rate of bursty traffic, these resources generate costs even during trafficless intervals.The new Asynchronous Transfer Mode (ATM) technology has the potential to respond to such shortcomings in today's systems and to meet tomorrow's communications requirements in a very cost-efficient way.As only one common network needs to be designed, the overall costs of design, installation, operation, and maintenance should be reduced.

The Available Bit Rate (ABR) service includes a feedback control that allows the characteristics of the connection to be changed during its lifetime.

When establishing a connection, the user is allowed to specify an Ôexpected category of service'.

The five ATM service categories represent new service building-blocks that make it possible for users to select specific combinations of traffic and performance parameters (Quality of Service, or Qo S), thereby providing a much greater degree of flexibility and fairness in the network's utilisation.

In its preparation of a ground infrastructure to support the future operation of the Columbus Orbital Facility (COF) and the Automated Transfer Vehicle (ATV), ESA has already defined a communications network that will exploit the benefits of Asynchronous Transfer Mode (ATM).

To validate the applicability of ATM technology for meeting the various service requirements, ESOC, in cooperation with Deutsche Telekom, has set up an ATM Testbed, which in the initial phase will serve to prove the concept.
