Performance Evaluation of a Resource-E.cient Provisioning Framework (RPF) in Service Di.erentiated Survivable WDM Networks Subject to Wavelength-Continuity Constraint

摘要：

Performance of a resource-e.cient provisioning framework (RPF) is evaluated in this paper in wavelengthcontinuous optical networks under static tra.c. The structure of the survivable routing problem is unraveled by an integer linear programming (ILP) model. Numerical results from direct ILP approaches show that the RPF still achieves more than 10％ capacity savings over the traditional provisioning framework when subject to the wavelength-continuity constraint. Next, Resource-E.cient Two-stEp Routing subject toWavelength-ConTinuity constraint (RETER-WCT) algorithm is developed to overcome the drawback of the ILP approach.
