1/10/20031 End-to-end QoS in the users' point of view ITU-T Workshop Geneva 1-3 October 2003 P-Y Hébert - ETSI

1/10/20032 QoS in the current Telecom world With the various emerging technologies (Mobiles network, VoIP,VPN) and the current competition Telecom service are delivered with very different QoS levels. To get the QoS they expect users have to rely on regulation or on agreement with their supplier In any case, standards are needed to monitor the QoS provided.

1/10/20033 Users' concerns and QoS standards Today, any technical body in any standardization organization refers to users' QoS requirements. Each of these TBs has different purposes: 3means to improve the technical QoS 3measurement methods of the QoS 3definition of QoS service classes All of them have in mind the technical quality Few of them are taking into account the users' concerns about the QoS
