The performance of a TDMA satellite system for non real-time and real-time traffic

This paper is divided into two sections. The first section presents the performance of the satellite capacity allocation algorithm for n on-real time traffic used in the FODA/IBEA system.A newfeature, called pre-assignment mode, improves the end--to--end delay during the transient provoked by a traffic step when the system is scarcely loaded. The experimental results obtained with four stations on the ITALSAT satellite are reported. The behaviour of the system in both stationary and transient loading conditions analysed. ln the second section snrtily presented the packer atrizttival time jitter which affects isochronous data when a satellite network, accessed via the FODA/IBEA-TDMA system, is crossed. Experimental results, obtained with three active stations on the ITALSAT satellite, are also presented. They confirm the analytic results. As a consequence of the study, the length of a jitter absorbing buffer is indicated.
