10. Q-Factor
The Q-Factor is a number that represents the quality of the network. You can
choose if you want to use the 0 to 5000 range, commonly used in the Automotive
industry, or a percentage .
A value of 5000 or a percentage of 100 is excellent and 0 is critical or unmeasurable.
Additionally, a color coding is used to emphasize the severity. Normally the color
should be green, meaning excellent or good. Yellow is subpar but not critical, e.g.
attention recommended. Red means a bad, critical or urgent issue.
10.1 Multiple Q-Factors
There are multiple Q-Factors in use in the tool:
• A Q-Factor for each network device, which indicates the quality for a single network device.
Calculation of this Q-Factor is based on a weight of:
o
Network link load: the bandwidth usage on a certain port of a device, is used to determine the
value. In general, the lower the load, the higher the Q-Factor.
o
In/Out errors: the number of errors per port of a device.
o
Ping packet loss: the number of unanswered ping requests.
• A single overall Q-Factor, indicating the quality of a complete network. Currently the overall Q-Factor
equals to the lowest Q-Factor of an individual network device.
