It employs Cournot and Bertrand games to model competition among service providers and network providers, respectively, and develops a novel unified model to capture the interaction and competition among these players in a “service-oriented” Internet. Incentives for service and network innovation are studied in this model.Internetservice providernetwork providercompetitioninnovationeconomic modelDigital Communications and NetworkingManagement Information SystemsPresentation
