5.3 Software Reliability
The software reliability of the RRU3606 is ensured by:
Periodic Check on Key Resources
Process Monitoring
Data Check
Fault Isolation
Log Function
5.3.1 Periodic Check on Key Resources
The RRU3606 checks the software resources that are occupied for a long time. If it
finds that certain resource becomes unavailable owing to a software error, it will release
the resource and outputs logs and alarms.
5.3.2 Process Monitoring
Process monitoring provides a channel for outputting various software and hardware
faults while the software is running. This function helps monitor the running status of a
specific task or system, and reports the information to associated devices.
5.3.3 Data Check
Data check consists of the following contents:
Checking the consistency of data on different processing boards, restoring the
data, and outputting logs and alarms.
Checking the consistency of the data entered by the user to ensure correct
reference relation among data.
Restoring the data to the initial state when the modification of some data fails.
5.3.4 Fault Isolation
In the RRU3606, if a fault occurs to a software module, other software modules will not
be affected.
The RRU3606 software also features powerful fault tolerance and correction capability.
A minor operation exception does not cause the system to restart.
5.3.5 Log Function
The O&M software can automatically record user's operations and save them into a log
file.
When an unknown error occurs to the system, you can refer to the log files to find out
the normal status for the purpose of fault location or data restoration.
