摘要
针对电信级网络的特点,提出了一种双机热备份容错系统实现方案。对双机热备份中的故障检测、故障恢复以及主备用资源一致性等关键问题进行了研究。对于瞬时故障、间歇性故障的容错采用软件冗余方法,而永久性故障则采用硬件冗余方法来解决,使系统可靠性有了进一步的提高。
According to the features of telecom network, an implementation scheme of duplicated hot - redundancy system for telecom network is presented. Such key techniques as fault detection, fault recovering and consistency of host and backup resources are studied. A method of software redundancy is adopted to deal with instantaneous and intermittent faults, and hardware redundancy to permanent faults, which makes the system reliability further improved.
