High availability today plays an important role in protecting continuous running of critical telecommunication equipments.When the hardware or the software goes wrong,high availability technologies can help the system to maintain normal.In order to improve the robustness of telecommunication equipments in the presence of errors, this paper analysed the high availability requirements of telecommunication equipments.Based on carrier grade operating systemCGEL (Carrier Grade Embedded Linux),this paper proposed and implemented a series of high availability designs,including of condition monitoring; error control; failover; on-line operations.The functions of these high availability designs are relative independent,but closely related each other.The experimental results show that these designs can help telecom equipments to effectively resist the hardware and software failures,and ensure non-stop telecom system for stable operation.
