Patent ID: 7990876

Claim:
A method for reconfiguring a telecommunications transport network after addition or removal of a network resource, the method comprising: identifying a sequence of single circuit movements to modify the network from a set of n actual circuits CA i (i=1, . . . , n), each satisfying a corresponding demand R i to a set of feasible intermediate circuits CI i which continue to satisfy the demands R i and which best approximate a series of target circuits CT i , comprising: (a) initializing, at a network simulator, the circuit set CI to CA; (b) for each demand R i still to be processed (i) calculating, at the network simulator, one or more candidate replacement circuits CI i , each candidate replacement circuit CI i satisfying the demand R i and having a lower cost difference with respect to the corresponding target circuit CT i than the current circuit CI i satisfying the demand R i ; (ii) replacing, at the network simulator, the current circuit CI i with the candidate replacement circuit CI i having the least cost difference; and (iii) marking, at the network simulator, the demand R i as having been processed; and (c) identifying, at the network simulator, the sequence of single circuit movements with which circuits CI i were replaced as the series of single circuit movements to modify the network.
