IP Networking and MediaCom 2004 Study Group 12 and ITU QoS Coordination Dr. Charles (Chuck) Dvorak SG12 Vice-Chairman Introduce self report is in doc 21 and 22 IP Networking and MediaCom 2004

IP Networking and MediaCom 2004 Where are the world’s QOS experts? A primary core competence of the ITU-T is the substantial expertise that it has across several Study Groups in the areas of QOS and Performance. The experts who work in the ITU-T do related work in regional SDOs (for example, ETSI, T1, TTC), but nowhere else does this same level of expertise reside.

IP Networking and MediaCom 2004 SG12 Area of Responsibility End-to-end transmission performance of networks, terminals and their interactions, in relation to the perceived quality and acceptance by users of text, speech, and image applications; including the related transmission implications of all networks (PDH, SDH, ATM and IP) and terminals.

IP Networking and MediaCom 2004 Scope of Question 14/12 Emphasize uniqueness of 12: methodologies terminals user applications mention relation to 13, 16 IP Networking and MediaCom 2004

IP Networking and MediaCom 2004 SG12 as the QOS Lead SG Internal to the ITU-T, provide a roadmap for QOS activities that can be used to identify, communicate and resolve QoS-related issues. External to the ITU-T, improve the visibility and utilisation of ITU-T expertise in QoS, and better leverage this expertise in specifications being developed elsewhere in the industry.

IP Networking and MediaCom 2004 One example of an industry-wide issue End-end performance and allocation of objectives can be done for an end-to-end architecture like that of the PSTN. But the Internet is not an end-to-end network, but a set of protocols that work across domains. How to do effective performance planning?
