Embodiments generally disclosed herein include methods and systems for calculating incremental network costs between logical city pairs in a network (each city pair being in communication across the network via one or more physical links). For example, the method includes a cost analyzer that, for each physical link in the network, determines a steady state capacity allocation associated with each city pair in the network and, in the same vein, determines a restoration capacity allocation associated with each city pair in the network. The cost analyzer is capable of calculating an incremental cost per unit of traffic for a given city pair based on: i) the steady state capacity allocation and a restoration capacity allocation associated with a given city pair, as compared to, ii) the aggregate steady state capacity allocations and restoration capacity allocations associated with each city pair in the network.
