Paper Details

Due to high traffic variability and significant contribution to CAPEX and OPEX, and expected highreliability, it is no longer practical to construct IP backbone networks by connecting many standalone componentswithout careful planning and design as it is commonly done with the bandwidth overprovision approach. Innovation isrequired to support growth and proliferation of services and devices while enabling greater efficiencies that driveconsolidation and reduction in costs. In this paper, a comparative study on the optimally designed and bandwidthoverprovision models of IP backbone network is carried out. Both models were developed by a combination of propertraffic model selection and analysis, and the use of computer modelling and simulating tools in the framework of adoctoral thesis. Riverbed Modeler was first used to optimally design the IP backbone network topology for Benue State inNigeria. Then, the topology of the IP backbone network was developed based on the generic bandwidth overprovisionmodel and converted into a simulation model also in the Riverbed modeler environment. Then the generalities of the twomodels were used to perform comparative analyses of the optimally designed model against the bandwidth overprovisionmodel. The results of the study verified that the bandwidth overprovision model is predisposed to inefficient utilization ofbandwidth and network resources. This leads to the conclusion that IP backbone networks need to be designed optimallyinstead of the bandwidth overprovision approach
