Abstract

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.
