The convergence between cloud computing and tele- com networks could significantly reduce costs and bring new business opportunities for operators. Currently, traditional teleeom operators are embarrassed by the fact that the increase in revenue cannot catch up with the quick growth of users and the expansion of networks. With the introduction of the cloud computing technology, operators can virtualize the network functions through low-cost COTS IT hardware All kinds of existing services can be cloudifled and thus obtain the benefits of statistical multiplexing among IT resources. With the Teleo Cloud architecture, operators can manage both IT infrastructures and network resources intelligently in order to adapt to the dynamic demands from the application and to establish open platforms for developing new services.展开更多
