Different services and applications need different levels of Quality of Service. How is the Broadband Forum facilitating QoS and the associated Quality of customer Experience (QoE)?
Some of the TRs and work in process to enhance Quality of Experience: • TR-126 provides a compendium of provisioning and management options for ensuring appropriate quality levels of different applications, such as the requirements for IPTV (both standard definition and high-definition) • This work was extensively liaised to standards bodies like ATIS and ITU who used it to inform much of their own work in this area. • TR-101 provides Service providers with a roadmap for how to migrate off an ATM access aggregation network to IP Ethernet based: • Blueprint for how to build a multiservice/triple-play broadband network and includes the functional requirements of all the key network elements (Residential Gateway/DSL router, Access Node/DSLAM, aggregation network and Broadband Network Gateway (BNG). • Functional requirements to cover the capabilities needed to deliver IPTV with multicast and QoS (see also TR-92 for more background on BNG QoS requirements such as hierarchical scheduling).
