Abstract: The paper analyses the properties of cyber physical system (CPS) for distribution network and the differences to telecom internet system, and points out that the CPS is characterized by that the communication network is involved in automatic process. The communication requirements are divided into two aspects including IT dataflow and OT control process, and their communication parameters and reliability mechanism are analyzed. Then, the universal carrying network model is proposed to improve the efficiency and ability of network resources management, and a multi-objective resource allocation scheme is established to meet the different requirements of IT and OT. Finally, the model and scheme is proved to be reasonable through a case study of a typical distribution network CPS.

Key words: smart distribution network, cyber physical system (CPS), communication network, network virtualization
