The System of Active Immunization and Diagnosis (SAID) is an intelligent fault diagnosis system that automatically diagnoses and rectifies some faults by simulating human operations in troubleshooting.
In a network, if services cannot be restored after being interrupted, serious consequences will occur. Currently, the reliability measures of devices are implemented through various detection mechanisms. Once a device fault is detected, an alarm is reported, and a log is recorded. After receiving a fault report, maintenance personnel often fail to collect fault symptoms in a timely manner. As a result, fault location is difficult and the problem cannot be solved completely, affecting the healthy running of the device. Therefore, an intelligent proactive immune diagnosis system needs to be built in the device to enable the device to automatically collect fault information and diagnose faults so that services can be restored. The system improves the self-healing capability and maintainability of the device.
