摘要
文章结合国家电网公司新一代IMS电话交换网建设与需求,深入介绍了网络功能虚拟化(Network Function Virtualization,NFV)技术发展及在电信网络中的应用情况,重点分析了NFV在运营商IMS交换网中的应用模式和部署策略,结合电力IMS交换网建设,分析了IMS网络虚拟化的应用场景,提出了电力IMS核心网的虚拟化方法和流程,以实现一套IMS硬件设备承载多套IMS虚拟网元,并对虚拟化后IMS网元的性能和网络的可靠性进行了分析,最后结合实际建设情况,给出了应用案例。
Combining with the construction of a new generation of IMS telephone switching networks of SGCC, this paper further introduced the NFV technology development and its application in the telecom network, and analyzed the NFV application mode and deployment strategy. According to the electric power IMS core equipment construction, this paper analyzed application scenarios of IMS network virtualization, proposed a method and process of power IMS core network virtualization, which could use one set of IMS hardware device to carry more virtualized IMS network equipments. Finally, it evaluated the performance and the reliability of the virtualized IMS network elements. With the actual construction situation, an application case is given.
