The application of cloud computing to core network becomes possible because of the centralization of telecom equipment and the wide use of the ATCA equipment.In this article
we propose the necessity and feasibility of the application of cloud computing in core network
through analyzing the characteristics of present equipment of core network
characteristics of cloud computing
and also the evolution of the next generation of equipment provided by the mainstream manufacturers.And we also put forward the strategy of how to introduce cloud computing into core network and the future program based on the characteristics of present equipment
the conditions and possible problems of introducing cloud computing into core network
as well as the necessary changes of the associated systems.
