Paper Abstract

Performance of a resource-efficient provisioning framework (RPF) is evaluated in this paper in wavelength-continuous optical networks under static traffic. 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-Efficient Two-stEp Routing subject to Wavelength-ConTinuity constraint (RETER-WCT) algorithm is developed to overcome the drawback of the ILP approach.
