ADAMANTIUM Measurable Results

• Initial conditions and alarm thresholds

Through a first set of tests, the IPTV service is degraded with different intensities.
E.g., the relation between PQoS and experienced packet losses is shown in next figures. ADAMANTIUM is initially configured to launch warning procedures (codec adaptations) at MOS=3 threshold and red alarms (network adaptations) are generated at MOS=2 threshold.

Under these circumstances, users are asked to assess when they would require the Warning and Red Alarms to be launched.

	Average PQoS (MOS)	Average packet loss
Warning Alarm	3.05	1.64%
Red Alarm	1.87	3.45%

• ADAMANTIUM enhancements in terms of media quality

Once established the specific thresholds for the considered IPTV service, users are required to evaluate the service experience under different conditions with ADAMANTIUM capabilities leading to automated adaptation actions.

Service Condition	Average PQoS over all users
Non-degraged service	4.51
Degraded network: service-level adaptations	3.85
Degraded network: network-level adaptations	4

• ADAMANTIUM capabilities in terms of response time

First of all, users are required to assess the service experience due to the initial delay in the communication. This measure allows us to evaluate the impact of the deployed IMS infrastructure itself due to the required signalling procedures. The tests were performed using the IMS-compatible GStreamer implementation that was developed based on the appropriate moderation of its typical non-IMS version.

Afterwards, users are required to evaluate the response time of the system when service-level adaptations are performed.

Finally, users are asked to evaluate the perceived response time of the system when severe degradations are introduced and network adaptations are required to mitigate the problem. As can be observed, the perceived adaptation latency is lower in this case.
