Summary
Some parts of Internet are good enough to provide good Internet telephony voice quality
The potential is growing rapidly
Reliability does not approach real phone system
We do not understand how the QoS effects things
- need the instrumented testbed
- need to simplify & automate the measurement process
- measurements with higher statistics to investigate impact of load on jitter and QoS on jitter when under load
- look at impact of other QoS tools or settings
