This record presents a survey from the traffic administration issues inside the designing and implementation of satellite-ATM networks. First a reference satellite-ATM network buildings is offered along with an overview in the service categories available in CREDIT networks. The error qualities of satellite tv channels, and techniques to enhance the error attributes, and the effect on ATM network performance are then talked about. A wait model for satellite sites and the major components of delay and postpone variation are described. A survey of design choices for TCP over UBR, GFR and ABR companies in ATM is offered next. The primary focuses is definitely on visitors management concerns. Several recommendations on the design choices for successfully carrying data services over satellite-ATM networks will be presented.

1 ) Introduction

ATM technology is expected to give quality of service structured networks that support tone, video and data applications. ATM was originally created for fiber structured terrestrial systems that show low latencies and low error prices. With the widespread availability of multimedia system technology, and an increasing demand for electronic on-line across the world, satellite networks may play an indispensable part in the deployment of global networks. Ka-band geostationary satellites using the gigahertz frequency variety can reach user ports across a lot of the populated globe. As a result, ATM based satellite television networks can be effectively accustomed to provide real-time as well as non-real time marketing communications services to remote areas.

Satellite telecoms technology offers a number of advantages above traditional terrestrial point-to-point networks [AKYL97]. These include,

• wide geographic coverage including interconnection of " ATM islands”,

• multipoint to multipoint communications facilitated by inherent...
