【摘要】 设计了一种适用于配电自动化以及相似环境的通信网络,它由双光纤环构成,使用GFP协议封装信息,在环上传递分组。此网络接入灵活、路由机制简单、支持QoS和流量控制、保护恢复迅速。测试表明本系统具有较高的链路利用率、低传输时延和恢复时间。目前生产的设备在小规模网络环境下运行正常。更多还原

【Abstract】 This paper presented a communication network for Distribution Automation System and similar circumstances. It consists of tow optical rings, encapsulates information with GFP, and transmits packets on the rings. This network has easy accessing and simple routing mechanisms. It supports QoS and rapid protection. Simulation proved it has high resource utility ratio, low transmission and restoration delay. Equipments produced now worked properly in small-scale networks.更多还原
