Research on the Application of SPN in Power Comm unication Network

Energy revolution and digital revolution are jointly promoting the transformation and upgrading of traditional power grid to digital power grid. The digital power grid is facing the demand for two-way transmission of widely distributed, large connections and massive data, which poses a great challenge to the power communication infrastructure. SPN is new generation of end-to-end hierarchical switching network technology system, which based on multilayer convergence, which is able to carry out comprehensive bearing of high-quality private line services and realize comprehensive service transmission with large bandwidth, low latency and high efficiency, and has good applicability to power communication networks. From the technical architecture and key technologies of SPN, combined with the existing architecture and business characteristics of power communication network, this paper puts forward the scheme of applying SPN network in power industry from two aspects of service bearing and networking mode.
