Abstract
A method for generating an optimized solution for assigning traffic loads to channels in SONET rings in cooperation with a computer having sufficient memory. The method utilizes a Mixed Integer Program (MIP) having corresponding variables necessary to model the cost of Terminal Multiplexers, Add/Drop Multiplexers and corresponding interface ports necessary to route the desired traffic loads. By routing traffic loads to reduce computation time and imposing mathematical bounds on the MIP variables, the number of possible MIP solutions is reduced. The Mixed integer Program is minimized in accordance with the traffic routing and imposed mathematical bounds such that an electrical signal is generated which corresponds to the optimized traffic load assignment information. The signal is converted to digital format whereupon it may be retrieved from computer memory and displayed to the user.
