  • Method and apparatus for providing composite link assignment in network design
    Patent number: 8098679
    Abstract: A method and apparatus for composite link assignment are provided such that network capacity is sufficient to handle all the traffic (e.g., load) while an objective function, e.g., the total cost of the capacity is minimized. The present method receives a plurality of weights for a plurality of arcs and a load for the network. An objective function is selected for minimization, where the present method then determines the composite link assignment to handle the load while the objective function is minimized. In one embodiment, the composite link assignment comprises a plurality of different link types for the plurality of arcs.
