Claim One:
1. A method of mapping virtual optical networks (VONs) to a physical network that includes one or more physical nodes and one or more physical links that connect the physical nodes, the method comprising: reading physical network information representative of characteristics of the physical nodes and the physical links, one or more VON demands, and one or more technology constraints of the physical network; determining whether an iteration parameter violates an iterative condition that determines whether to continue processing the VON demands; in response to the iteration parameter not violating the iterative condition, determining whether there are unprocessed subgroups of the VON demands; in response to there being one or more unprocessed subgroups, selecting a subgroup of the VONs; computing feasible mapping patterns for the subgroup of the VONs; finding a size of a largest subset of the subgroup that has a feasible mapping and slot assignment solution; finding a mapping solution of the subset that has a feasible slot assignment; and finding a slot assignment of the mapping solution.
