Conclusions & Further Work
>
Conclusions
•
New architecture with distributed service intelligence
–
•
Service Plane solution introduces new services in access multiplexer
Implementation & demonstration
of two services within the IST-MUSE project
–
D-SBC: improved Scalability / Robustness / Quality / Security
– Video QoS Monitoring for VoD (TCP) & Broadcast TV (RTP/RTCP)
services to improve user Quality of Experience (QoE)
>
Further work
•
QoS monitoring is being translated in QoE improvement/control
–
•
See “Autonomic QoE Optimization in the Access Node Knowledge
Plane”.
Other services are being developed.
