The difference between dedicated and shared protection is well known. In this paper we investigate these ideas applied to sharing power budgets of links. When defining protection paths not as a “hot stand-by” but rather as a “cold stand-by” the power needed for protection will be lower; therefore the routeable distance of certain connections should be longer, that increases the number of routeable demands. In this paper we present simulation results to show that in reality with the introduction of shared protection for Physical Impairment Constrained Routing (PICR) in large or saturated networks the number of routeable demands is lowered.
