Abstract :
We consider protection and restoration mechanisms for hierarchical optical networks with different granularities of paths (wavelengths and wavebands). We formulate an integer linear programming description for the problem and propose a shared-path waveband protection algorithm. We further demonstrate its efficiency by analyzing its equipment cost and capacity utilization.
