Workshop on "End-to-End QoE/QoS"
Geneva, 14-16 June 2006  
Contact: tsbworkshops@itu.int

Introduction
This workshop brought together experts from all over the world who are involved in the definition and the delivery of end-to-end quality of experience (QoE) and quality of service (QoS). Several developments have been recently achieved on QoE and QoS, in particular related to NGN, but also in home networking, quality prediction, terminals, interoperability and for new services.
The workshop was organised by ITU-T SG12 which is the lead ITU-T Study Group on QoS and in charge of the development of recommendations on quality as perceived by the users.
For users, also for operators and Internet service providers, the end-to-end quality is one of the major factors to be achieved. During recent years, the new term of "QoE" has been introduced to make end-to-end QoS more clearly captures the experience of the users. In this field, several new developments have occurred. QoS now encompasses a wide range of services, including wider bandwidth for audio and speech, new multimedia services such as IPTV. Definition of new performance parameters and values, new assessment methodologies and new quality prediction models are needed. The workshop aimed to review recent progress from different SDOs and contribute to future efforts towards international standardization in QoE/QoS.
