摘要
主控板的主备倒换是通信设备稳定运行的关键技术。提出了一种基于硬件实现主备倒换的设计方案,并对其主要模块和关键实现技术进行了深入的研究。本设计具有较强的通用性和自适应性,能够提供主控板主备状态的切换以及主备板的MAC地址的处理。
In communication system, Main/Standby switch is one of key technologies, which can ensure stabilization and reliability of communication network. This paper presents a new design of main/stand switch based on hardware realization, and studies its main modules and key implementation technologies. This scheme is characteristics of compatibility and adaptability, and capable of switching of the Main/Standby state of Main control board and dealing with MAC address between the Main board and the Standby board.
