This paper proposes a QoS-Aware Optical Connection Setup Management scheme that uses the Earliest Deadline First (EDF) queueing discipline to schedule the setup of the optical connections. The benefits of this EDF-based scheme are twofold: it reduces the blocking probability since blocked connection requests due to resource unavailability are queued for possible future setup opportunities and it realizes QoS differentiation by ranking the blocked requests in the EDF queue according to their connection setup time requirements, which are viewed as deadlines during connection provisioning. As such, pending lesser delay-tolerant requests are guaranteed to experience better QoS than the ones having longer setup time requirements.
