DTCPN: A Digital Twin Cyber Platform Based on NFV

Existing network emulation or simulation platforms provide efficient way to analyze, test and evaluate new network technology and equipment. However, these platforms have disadvantages such as poor interactivity, model sensitive and low reality. To solve these problems, a Digital Twin Cyber Platform based on NFV (DTCPN) is proposed in this paper. Firstly, by analyzing the function principles of digital twin and NFV technology, a system model which combines the advantages of digital twin and NFV is proposed. Secondly, the working principle and advantages of DTCPN are presented. Thirdly, the prototype of DTCPN is designed and typical applications of DTCPN in network security, network management and network applications are presented. The evaluation results show that DTCPN works in a way free from network modeling and provide an easy interaction and high reality technology for network innovations.
