Aggressive resource reservation for OBS systems

nsari, N.   The aggressive reservation strategy in optical burst switching (OBS) systems is investigated. A success-probability-driven algorithm and a bandwidth-utilisation-driven algorithm are proposed to facilitate the authorsʹ recently proposed forward resource reservation transmission scheme (Liu and Ansari, Proc. IEEE Globecom, p.2777-81, 2002). The principles and the theoretical analysis of these two algorithms are presented and their performance is compared with respect to reservation success probability and bandwidth usage efficiency. Simulation results have validated the algorithms and the analysis.
