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

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


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

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


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
