Satellite link protocols design for the CODE system
Abstract
The design of satellite link protocols for Very Small Aperture Terminals (VSAT) systems is outlined. The CODE system (Cooperative Olympus Data Experiment) is a VSAT system with two main characteristics: very low bit error rate, and multiple access over FDM channels in the inbound link. The design of the link protocols for this system covers two main aspects: error control procedures and medium access control procedures. In order to analyze both aspects, a profile of the average user of the CODE system is defined in terms of types of traffic and of messages arrival and service rates for every type of traffic. An analysis of the mean time between failures is made, and the average delay and through-put for different access methods are computed, including stability analysis for Aloha-based systems.
