Abstract

Description
本发明涉及数据报文检测技术，尤其涉及一种实现链路检测的方法、装置及计算机存储介质。
为了满足对系统的高稳定性要求，在绝大多数系统中均采用一对一的链路容灾备份设计，即：当系统主链路出现故障时，通过将系统正在处理的业务从主链路切换至备份链路的方式达到业务不中断的目的，从而提高系统的稳定性。
在实际应用中，当需要进行链路切换时，系统在默认条件下认为备份链路当前处于正常工作状态，从而直接将系统正在处理的业务切换至备份链路。
然而，这种将系统正在处理的业务从主链路至备份链路的默认切换方式存在如下缺陷：由于系统无法判断备份链路的工作状态是否正常，因此，如果备份链路的工作状态为故障时，通过将主链路上的业务切换至备份链路上的方式仍会导致业务中断，使得系统在进行链路切换时存在很大程度上的不可预见性，从而无法提供整个系统的稳定性。
