OPN09-04: SSTF: A ´Shortest Setup Time First´ Optical Connections Setup Management Approach with Quantifiable Success Rate

The worldwide network domain tendency to evolve towards dynamic quality of service (QoS) enabled optical networks is imminent. In such an evolution, improving connection setup conditions is considered to be one of the major requirements. This paper proposes a novel connection setup management approach. The rationale behind this proposal lies in considering the optical connection setup time requirement as a (timely increasing) priority indicator during the setup/provisioning process. From this viewpoint, we adapt the well known earliest deadline first (EDF) scheduling discipline to the particular case of optical connection setup management, which consists in giving highest priority to the connection request having the shortest setup time requirement. Another originality of this paper stems from the proposal of a computational method for the assessment of optical connection setup success probability under the proposed management approach. The latter parameter, that is the connection setup success rate, is an important indicator for both optical operators and clients.
