The one districts and cities' network of detection in every 30 minutes measures topological diagram by gateway server using depth-first method traverses network topology
In the time delay of each router logic, packet loss, by the average delay of K GC group connector, average packet loss ratio, as router logic
Time delay, packet loss.
Set delay threshold T=4000ms, packet loss threshold value L=20%, when find certain router logic time delay > T or
The case where packet loss > L, terminal disconnection, generates warning information, the alarm table of database is written.It will go offline or network performance is inclined
Low terminal IP is sent to network failure evaluation module, calls network failure evaluation module.
When finding failed terminals, network failure evaluation module is called, if it is single terminal failure, is alerted to database
Terminal disconnection warning record is written in information table, if it is determined that be that network failure occurs in virtual link, such as network congestion, therefore
Hinder the terminal range that output failure influences in assessment report.
Fault alarm module is according to Fixed Time Interval, warning information table record in cycle detection database, if it find that
When new warning information, such as terminal disconnection, assessment of failure report etc., by Web page and Intranet mailing system, to network dimension
Shield personnel push network failure warning message.
