The Movable-Boundary Integrated CBR/Bursty-data Traffic protocol MB-ICBT is a new version of hybrid protocols supporting both, circuit- and packet-switching techniques in VSAT network environments. Circuit-switching is applied to CBR traffic connections, which are admitted in the system by a conventional DAMA technique. Bursty-data traffic, on the other hand is allowed to contend in a more complex version of slotted Aloha with anticipated reservation. A movable boundary policy is applied between the two traffic compartments to adapt to network loading conditions. The introduction of the anticipated reservation access for bursty-data, together with the movable-boundary policy, serve to minimize the collision resolution delay, largely significant in VSAT networks, and increase throughput for the bursty-data traffic. The MB-ICBT protocol is analysed and tested for different bursty-data traffic models and a telephone CBR service. Simulation results are shown to indicate the enhanced performance in terms of access delay for bursty data traffic, together with an improved overall channel throughput.
