Service Rich Access Networks: The Service Plane Solution -- 14 Broadband Europe, Antwerp 2007 All rights reserved © 2007, Alcatel-Lucent 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.
