ITU-T Study Group 12Performance, QoS and QoE
SG 12 Terms of Reference
Responsible for Recommendations on performance, quality of service (QoS) and quality of experience (QoE) for the full spectrum of terminals, networks and services ranging from speech over fixed circuit-based networks to multimedia applications over networks that are mobile and packet-based. Included in this scope are the operational aspects of performance, QoS and QoE.A special focus is given to interoperability to ensure end-to-end users' satisfaction.Lead SG for QoS and Performance

Terms of Reference (proposed)
Responsible for Recommendations on performance, quality of service (QoS) and quality of experience (QoE) for the full spectrum of terminals, networks and services ranging from speech over fixed circuit-based networks to multimedia applications over networks that are mobile and packet based. Included in this scope are the operational aspects of performance, QoS and QoE; the end-to-end quality aspects of interoperability; and the development of multimedia quality assessment methodologies, both subjective and objective.Lead SG for Performance, QoS and QoE

Examples of Future Work
QoE of Web-browsing and other appsFramework for invoking diagnostic funct.QoE requirements for telepresence; and telemeeting and conferencing servicesModels for Client Performance Metrics Multidimensional scaling quality assessmentObjective prediction of speech intelligibilityParametric non-intrusive A/V assessmentMany new subjective test methods needed

Conclusion
SG 12 works on all performance aspects (terminals, systems, networks, etc.), so the end-to-end view of the user is captured.Meaningful progress by SG 12 will happen in the future because it continues to evolve its work programme to address the performance, QoS and QoE of new technologies, networks and services, such as IPTV, advanced audio, Ethernet, home networking, multimedia, etc.

AcknowledgementsIn any standards development organization, substantial progress occurs because of the right balance of timely technical contributions and trusted, competent leadership. SG 12 is a role model for this statement—because of the Vice-Chairs, the WP chairs, chairs of the Groups that report to SG 12, the rapporteurs, the editors, and the many active participants. Thanks to all they did--and for making it fun!Many talented people on the TSB staff supported us really well. My sincere thanks to all who worked so hard in the background so that we could be successful in our efforts.For their dedication and diligence, special thanks to the TSB staff who were assigned to SG12: Judit Katona Kiss (our recently retired Counsellor), Hiroshi Ota, and Sarah Scott.
