  Responsible for Recommendations on the end-to-end transmission performance of terminals 
  and networks, in relation to the perceived quality and acceptance by users of text, data, 
  speech, and multi-media applications. Although this work includes the related transmission 
  implications of all networks and all telecommunication terminals, a special focus is given 
  to IP QoS, interoperability and implications for NGN, and also includes work on performance and resource management.Study Group 12 is the lead study group on quality of service and performance. |  |
