Evaluation and Comparison of Signaling Reservation Protocols for Grid over OBS Networks Employing Active Routers

Abstract

This paper evaluates and compares the performance of Grid over Optical Burst Switching (OBS) networks employing Active routers. Two signaling reservation schemes are considered: the Just Enough Time (JET) and a centrally controlled Wavelength Routed (WR) scheme. Analysis and simulation results show that the centrally controlled WR-OBS signaling scheme always outperforms the JET-OBS scheme in terms of job blocking rate and the time delay that a job suffers until it reaches the Grid service provider.
