N2 - Generally speaking, buffer requirement is not vital for JET-based optical burst switching (OBS). However, if deflection routing is enabled, optical buffers are necessary to solve the insufficient offset time problem. Another solution, which can alleviate buffering, is to lengthen offset time in the beginning. As previous work indicated, a burst with extra offset time has higher priority than that without extra offset time and quality-of-service (QoS) can be accomplished in this way. Therefore, we investigate the performance of deflection routing in prioritized JET-based optical burst-switched networks. A queuing model is proposed to approximate loss probability. We also evaluate the impact of deflection routing in arpanet-2 topology by simulation.
