Embodiment Construction

[0033] A method for reducing service interruption time provided by an embodiment of the present invention is that when a device fails to start normally due to a fault, for example, the device restarts repeatedly, at this time it is judged whether the fault is caused by the ECC memory of the device, and if so, Then shut down the operation of the ECC memory; and after shutting down, trigger the restart of the device, so as to resume the service operation after startup.

[0034] Wherein, the specific realization of the said determining whether the fault is caused by the ECC memory of the device includes that the ECC memory of the device can be detected separately, or by detecting all other faults in the device except the ECC memory The RAM memory chip performs fault detection, through troubleshooting, thereby knowing the state of the ECC memory, or detecting the working state of the ECC memory by other common means, wherein any fault detection method adopted for the ECC memory doe...

Abstract

The embodiment in the invention discloses a method for reducing the service interruption time. When equipment can not be normally started due to faults, determine whether the faults are caused by ECC memory of the equipment or not, if yes, shut down the operation of the ECC memory; trigger the equipment to restart and thereby recover service operations after starting. Meanwhile, the embodiment in the invention also discloses a method and means for testing faults of ECC memory of the equipment. When the equipment is broken down, the invention can timely shut down the broken ECC memory tested, thereby allow the equipment to recover service operations after being restarted. Avoid a long interruption of equipment services, and reduce the service interruption time of equipment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for reducing service interruption time. Background technique [0002] Soft failure is based on the unique failure mode of memory devices with RAM (Random Access Memory, random access memory), which corresponds to hard failure. Hard failure is the failure of the hardware itself of the device. This situation is called a soft failure. Generally, the lower the operating voltage of the device, the narrower the process line width, or the higher the altitude of the device's working environment, the greater the probability of soft failure of the device. For example, the probability of a soft failure for a memory using 0.13 micron technology is as high as 10,000-100,000 FITs (Failures In Time, FITs) per megabit, which is equivalent to a soft failure every few months or weeks on average. [0003] At present, in order to reduce the severity caused by the soft f...
