Motivation
Intermittent connection
Low speeds
Poor customer service
Unclear contracted conditions
Solution
Gather measurements of QoS parameters and use them as forensic evidence
Checkpoint
-
Uptime and Downtime
-
Connection speed
-
Present the results to the user in a secure manner
Evidence

Evaluating
System
Performance
-
The ISP will be simulated by a router
-
By changing the parameters of the router one can simulate the changing QoS parameters
-
We can then compare the settings with the results measured by the router
