An Improved Model of Blocking Probability in All-Optical Networks

摘要

We have developed a model of blocking probability in an All-Optical Network (AON) without wavelength changers and tested this model against simulations. The new model is an improvement of a model first proposed in [1].rnIn an AON, the signals remain in the optical domain from the origin to the destination. We consider AONs supporting point-to-point sessions between users using arbitrary fixed path routing algorithm. Without wavelength changers, a session must use the same wavelength on every fiber of the path. With wavelength changers, a session may use a different wavelength on each fiber it occupies. In either case, two sessions simultaneously using the same fiber must be on different wavelengths.
