5G移动通信网络作为一种新型融合性网络,其以“用户需求”为根本出发点,以网络架构及性能的提升为主要着力点,而SDN和NFV作为5G网络的两大主流技术,两者存在互补性,SND技术能够对网络连接进行集中管控和优化调度,而NFV技术则能够实现网络节点功能的虚拟化、智能化部署和弹性伸缩,为此,本文将SDN和NFV引入5G移动通信网络架构之中,分析了其应用优势,给出了设计思路,并深入剖析其主要功能。
As a new type of convergent network, 5G mobile communication network takes “user demand ” as its basic starting point and network architecture and performance improvement as the main focus. As the two mainstream technologies of 5G network, SDN and NFV SND technology can centralized control and optimal scheduling of network connections, while NFV technology can realize the virtualization, intelligent deployment and flexible scaling of network node functions. Therefore, this paper introduces SDN and NFV into 5G mobile communication Network architecture, analyzes its application advantages, gives the design ideas, and in-depth analysis of its main functions.
