7.4 The Real ISP’s Italian Backbone NetworkFigure 7.15: Objective function value in case of failure (LP results)81
7.5 Conclusion and validation of results7.5 Conclusion and validation of resultsIt has be proven that the developed LP model is a good candidate for the solutionof the congestion of a backbone network in case of a single edge failure.Comparison with default configuration, with current ISP’s configuration, andwith results of an IS-IS optimization process have highlighted the good performancesof the model. All results have been validated with a commercial simulationsoftware called OPNET Modeler [15].82
