2 ECOC Outline Introduction to MUSE Service plane Multimedia service enablers Conclusions

3 ECOC MUSE Overall Objective Multi service access network that provides secure connectivity between end-user terminals and edge in a multi-provider environment at a low cost for every European citizen. Multi service access network that provides secure connectivity between end-user terminals and edge in a multi-provider environment at a low cost for every European citizen. Mobile Service Provider Network Service Provider Internet Service Provider Application Service Provider Access Node Residential Gateway Edge Node Aggregation network First Mile

Carlos III de Madrid University of Essex Component vendors Phase I: Phase II: partners -100 PY/year (*) (**) (*) Only in phase I (**) Only in phase II

5 ECOC Outline Introduction to MUSE Service plane Service enabler Trends in access node technology Service plane Multimedia service enablers Conclusions

6 ECOC Service enablers Network service enablers Higher layer service enablers AAA QoS Secure Connectivity

7 ECOC Service enablers Monitoring Proxy Time shifted TV : Service plane Enhance deployment Conversational services Fixed mobile convergence Multimedia services

8 ECOC Access Platform evolution Time DSL Termination Ethernet Aggregation IP Subscriber Management Service & Application Complexity of Added Value Features Complexity of Added Value Features Operator Specific Requirements HW Platform Cost HW Platform Cost Feature Complexity Feature Complexity Platform Cost Platform Cost

9 ECOC Why to migrate intelligence in the access ? Quality (QoS): first fully trusted point close to the user – only point with complete view of all services per user Security: ingress/egress point to network Robustness: smaller number of users impacted in case of failure Scalablility: feasible data rates for DPI and processing

10 ECOC Service Plane Integrated in Switch board Integrated in Line card Separate Service Blade Service Plane Service C Service A Service B Control Plane (SW) Advanced Data Plane (HW)

11 ECOC Outline Introduction to MUSE Service plane Multimedia service enablers Quality of Experience Video aware traffic management Reliable video transport Time shifted TV P2P enhancements Monitoring and knowledge plane Conclusions

12 ECOC Quality of Experience QoS: Network parameters Bitrate Packet loss Delay, jitter QoE: User perception MOS (Mean Opinion Score) Visible pixel errors per hour Zapping delays Viewing mode (e.g. live, progressive download) Gaming: Fast response, but equal delay Best Effort Internet Service awareness in the network can improve the QoE

13 ECOC Video Aware Traffic Management Random drop : B, I, P picture and audio information equally affected IPBdBs Bd P Bs Bd P Bs Bd P Bs Bd IPBs Intelligent drop : only Bd picture drop (e.g. through WRED) Bit Rate per GOP IPBdBs Bd P Bs Bd P Bs Bd P Bs Bd IPBs

14 ECOC Video Aware Traffic Management Impact on QoE Random DropIntelligent Drop

15 ECOC Reliable video transport in access Bursts of packet loss on DSL or Wireless segments Detremental for Video services Solutions: FEC (Forward Error Correction) at application layer Retransmission proxy impulsive noise

16 ECOC FEC approach Recover lost packets at the STB with the help of redundant FEC information Standard solution Pro MPEG 20% extra BW to recover 1% packet loss XOR L1 L2 L3 L4 L5 C1 C2 C3 C4 C5 C6 C7 C8 COP#3 matrix Column FEC packets Row FEC packets FEC at encoder FEC enabled STB

17 ECOC Retransmission Proxy in Access Node caches packets for short time TCP RTP/UDP BW for retransmission is negligible Retransmission Request and buffer in STB Retransmission Proxy

18 ECOC Time shifted TV Real time broadcast # Requests 1 h1day1 week TSTV server Access CDN Server Regional VoD Server Central P2P interaction

19 ECOC Enhancing P2P services Babelgum TM Cache for P2P delivery DPI to trigger QoS

20 ECOC Monitoring Plane – Knowledge Plane Monitoring packet loss at ingress/egress point Analysis, correlation, fault localisation Trigger action to restore QoE

21 ECOC Outline Introduction to MUSE Service Plane Multimedia service enablers Conclusions

22 ECOC Conclusions Service enablers increase the QoE of multimedia applications Trend towards higher layer awareness in the access Service plane allows for flexible implementation

23 ECOC BB Access Lab trials SPC (FMC) at TNO Delft SPE (RoF) at TU/e SPB (Service Plane, MM) at DT Berlin SPE (CWDM) at HHI Berlin SPB (Distr. SBC) at TID Huesca SPC (FMC) at ACREO Kista Via IST MUPBED SPE (XL-PON) at BT Ipswich SPD (Distr. content & control ) at PTI Aveiro
