网络功能虚拟化技术利用标准化硬件平台和虚拟化技术,通过软硬件解耦重构通信运营商网络。通过介绍网络功能虚拟化技术的定义、发展过程、组网架构,对比分析网络功能虚拟化的优势与挑战,结合集团公司组织的三厂商、四城市外场试点以及纯控制网元云化测试应用,验证了硬件、系统安装、云管理、可靠性、网管、语音通话业务等六大类测试用例的一致性,为网络功能虚拟化技术的商用提供参考。
Network Functionality Virtualization technology utilizes a standardized hardware platform and virtualization technology to reconstruct the communications carrier network through hardware and software decoupling. By introducing the definition, development process and networking structure of network function virtualization technology, the advantages and the challenges of network function virtualization are compared and analyzed. Combined with the three vendors and four city pilot field and cloud control test application of pure control network organized by the group company, Verified the consistency of the six major types of test cases such as hardware, system installation, cloud management, reliability, network management and voice call services, and provided reference for the commercial use of network function virtualization technology.
