The software-defined network implements the separation of software and hardware, as well as a programmable network. however, the lack of consistent records of network data poses difficulties for network management, and heterogeneous device heterogeneity poses a hindrance to software-defined network interoperability. This paper summarizes the development status and existing problems of software-defined network, proposes a softwaredefined network data chain based on blockchain, realizes distributed consistent record of software-defined network data, and breaks the multi-vendor device isolation for fault recovery. Reduce the cost of network failure recovery and achieve unified scheduling of business capabilities.
