Abstract :
Deployment of fiber delay lines (FDLs) as a means of contention resolution is analytically studied. We consider a single-wavelength optical link equipped with a single FDL and assume that packets of fixed length arrive to the link asynchronously. The results obtained include accurate equations to calculate the congestion rate for different reservation scenarios including a prereservation scheme as well as a postreservation scheme with a specific number of circulations. Accuracy of the proposed model is validated through simulation.
