Abstract In this paper we analyse the performance of an Adaptive Random-Reservation Medium Access Control (MAC) protocol which can support all ATM service classes while(More)
This paper presents the performance studies of ATM via satellite based on experiments implemented by the RACE II CATALYST project R2074. The purpose of the project was to develop an ATM satellite link for the future B-ISDN services, particularly for the interconnections of the ATM testbeds which are in the form of broadband islands. Then initial ATM based(More)
In this paper we present and evaluate a hybrid-modular multiple access protocol for ATM transmission in a multiservice satellite system. Given appropriate synchronization and Doppler (shift) compensation, the protocol components can cope with the dynamics of the satellite constellation and are suitable to both mobile and fixed user environments. The general(More)
Abstract: This paper presents the preliminary results of the research to use Very Small Aperture Terminal (VSAT) systems for ATM (Asynchronous Transfer Mode) services. We consider a scenario where a large number of VSATs are interconnected by an On Board Processing (OBP) satellite with cell switching capabilities. Statistical multiplexing is used to take(More)
This paper investigates how the performance of a preventive control scheme using a Leaky Bucket can be improved by using a feedback control loop. The proposed scheme is adaptive to congestion within the network. The queue occupancy of a network element is used as an indication of congestion and the individual sources, whose transmission path passes through(More)
