摘　　要：根据数据网采用的技术来分代,从模拟数据网起到采用分组统计复用技术数据网(以IP网为代表)已经发展了4代。网络5.0是以第五代数据网为技术主体的网络技术,是对传统互联网的继承、发展和创新。网络5.0采用分代研究、确定目标,以四大应用场景为基础,对IP网前向兼容和能力包容。在业务流的分类与分级、可信与安全、确定性(3个维度),虚拟网和业务网与承载网的接口和协议等方面提出新的理念。According to the technology adopted by the data network to divide the generations,from the simulated data network to the technical data network(IP network is the representative one),the data network has developed for 4 generations.Network 5.0 is a network technology with the fifth generation of data network as the main technology.It is the inheritance,development and innovation of the traditional Internet.Network 5.0 adopts generation research and target determination.Based on four application scenarios,it is forward compatible with and capability tolerant of IP network.This paper puts forward new concepts in the dimensions of classification and grading,credibility and security,certainty,as well as interface and protocol among virtual network,business network and bearer network.
