However, in practical applications, there are some problems in the core network of 3G network, such as uneven load, poor fault tolerance, and low flexibility of traditional 3G core network. In order to solve these problems, this paper proposes an IP-based transformation architecture for 3G core network and studies its survivability.Firstly, this paper analyzes the problems existing in the current 3G core network and proposes the idea of IP-based transformation. Then, this paper designs the IP-based transformation scheme for 3G core network, including core network SDN controller, data center network, virtualization technology and other key technologies. Next, this paper tests the survivability of the IP-based transformed 3G core network. Through simulation experiments and actual tests, the superiority of this scheme in load balancing, fault tolerance, and flexibility is verified.精品文档---下载后可任意编辑Finally, this paper summarizes the research achievements in this stage and proposes the prospects for the next step of research work.Keywords: 3G core network; IP-based transformation; SDN controller; data center network; virtualization technology; survivability.
