NFV虚拟化网元的特征及与传统网元的异同

Feature of NFV Virtualized NE and its Difference and Similarity with Traditional NE

为了说明NFV虚拟化网络中网元功能的特征及其与传统网元的异同,从构成方式、功能差异及实现流程、性能、可靠性、安全、操作维护、生成速度、成本等方面进行比较,并针对虚拟化网络和传统网络的性能、可靠性、安全进行分析,同时提出改进方法。

In order to explain the feature of the network element （NE） function in the virtualized network of the network function virtualization （NFV） and its similarity and difference with the traditional NE, the formation, functional difference, working process, performance, reliability, security, operation, maintenance, generation speed and cost were compared with each other. In addition, the improved method was put forward according to the analyses on the pcrformance, reliability and security of the virtualized network and the traditional network.
