Research on CDN network architecture design and safety protection for power grid

Abstract

Based on a large amount of investigation, analysis and research of the application system status and network status of the power grid, the paper introduces a novel CDN network architecture for power grid, which has the power grid characteristics and meets the power grid requirements. In order to ensure the efficiency and stability of CDN system, the CDN network architecture key technologies include virtual CDN technology, software defined CDN technology, network measurement technology based on data analysis, database for CDN network, CDN management platform and load balance. Also, there are four aspects to ensure the security of CDN system, as network security, safety management system, CDN equipment safety and anti-leech mechanism which can be a reference for the construction of CDN network in power grid and other industries.
