Abstract:

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.

Key words: analog network, digital network, transmission network, data network, the next-generation network
