Patent ID: 7787770

Claim:
A method for co-modelling a simulated packet network and a simulated optical network over which the simulated packet network operates on a computer comprising a processor and a computer-readable medium storing computer executable instructions for co-modelling the simulated packet network and the simulated optical network, the simulated packet network representing a plurality of packet links between packet network nodes and the simulated optical network representing a plurality of optical links between optical network nodes, the method comprising the steps of: the processor generating a basic packet capacity comprising a capacity value for each packet link based on packet network topology information and packet traffic information; and the processor generating a basic optical capacity comprising a capacity value for each optical link based on optical network topology information and the basic packet capacity, wherein the combination of the basic packet capacity and the basic optical capacity applied to the simulated packet network and a simulated optical network produce a co-modelled simulated packet transport network; wherein the step of the processor generating a basic packet capacity further comprises the steps of: the processor combining the packet network topology information in the form of a packet network topology input to the processor and the packet traffic information in the form of a packet traffic matrix input to the processor to create the simulated packet network; and the processor assigning each packet link of the simulated packet network a flow to create the basic packet capacity for the simulated packet network; and wherein the step of the processor generating a basic optical capacity comprises the steps of: the processor combining the optical network topology information in the form of an optical network topology input to the processor and the basic packet capacity to form the simulated optical network; and the processor assigning each optical link of the simulated optical network a flow to create the basic optical capacity for the simulated optical network.
