Resum
We propose a new recovery scheme, called multi-path recovery (MPR), specifically designed for flexgrid-based optical networks. It combines protection and restoration schemes to jointly recover, in part or totally, the bitrate requested by client demands in case of failure. We define the bitrate squeezed recovery optimization (BRASERO) problem to maximize the amount of bitrate which is recovered in case of failure of any single fiber link; a mixed integer linear programming formulation for the BR...
