双平面交换机在配电通信网中的应用OA

With the rapid development of services such as distribution automation and distributed energy access,the distribution communication network faces higher requirements in terms of reliability,security isolation,and bandwidth capacity.The traditional single-plane switch networking approach has issues such as high risk of single-point failure,poor service isolation,and complex operation and maintenance,making it difficult to meet the development needs of new distribution systems.A distribution communication network bearing architecture based on dual-plane industrial Ethernet switches is proposed.This architecture achieves physical isolation and redundant bearing of production control and management information services within a single device through the core application of Wavelength Division Multiplexing(WDM)technology and optical port Bypass technology.Field pilot applications show that this solution can achieve millisecond-level fault self-healing switching,raising network reliability to over 99.999%,maintaining end-to-end service transmission delay within 50 ms,and effectively simplifying the network structure,reducing construction and operation and maintenance costs.The research results provide key technical support and practical paths for building a safe,reliable,efficient,and flexible new generation of intelligent distribution communication network.
