International Telecommunication Union Workshop on End-to-End Quality of Service.What is it? How do we get it? Geneva, 1-3 October 2003 ITU-T QoS Workshop Session 5 Specification and Signalling of IP QoS Classes 3 October 2003

ITU-T October 2003 Workshop on End-to-End Quality of Service. What is it? How do we get it? Session Context Pr(e/o)mise of IP/PSTN Convergence o Cost savings through technology consolidation o Industry growth through service innovation QoS Signaling: The Nexus and Gordian Knot o Convergence presupposes toll quality voice on a multi-service, multi-provider IP infrastructure o Toll quality voice requires service differentiation and resource control,  QoS (and flow) signaling  Signaling QoS (and flow) parameters will be essential to successful IP/PSTN convergence

ITU-T October 2003 Workshop on End-to-End Quality of Service. What is it? How do we get it? Objectives and Session Plan o Objectives Clarify QOS requirements for multi-service IP-based networks supporting telephony Explore how those requirements will be supported by QoS signalling among networks o Session Plan Introduction and Overview …………….….5 m. Panelist presentations 1-3..…………….75 m. (Coffee break) 30 m. Panelist presentations 4-6.……………..75 m. Open discussion period …………………….20 m. Conclusions and action items ….…………5 m. ______________ 210 m. Please defer questions to the discussion period.

ITU-T October 2003 Workshop on End-to-End Quality of Service. What is it? How do we get it?
