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

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
