4 Psytechnics 2008 Enter real-time communications applications Service Assurance; NMS IP QoS Information for Data Real-time Voice and Video Communications Video: frame- type, frame- rate, image- size, codec-type Voice: noise, echo, speech/ sound levels, distortion, delay, codec-type IP Network

5 Different information needed for voice and video performance management Psytechnics 2008 Service Assurance; NMS IP QoS Information for Data Real-time Voice and Video Communications Additional IP Information for Real-Time Video: frame- type, frame- rate, image- size, codec-type Voice: noise, echo, speech/ sound levels, distortion, delay, codec-type IP Network

6 Different information needed for voice and video performance management Psytechnics 2008 IP QoS Information for Data Additional IP Information for Real-Time Service Assurance; NMS Application level problems? IP-QoS only tools? Performance green light (incorrect!) No issue detected, no diagnosis What do you fix? Leading to: Ad hoc, trial and error tech support Real-time Inefficiency and cost due to lack of issue visibility Voice and Video Stalled deployment Communications (aging inventory, revenue recognition, penalties) Loss of confidence Video: frame- type, frame- rate, image- size, codec-type Voice: noise, echo, speech/ sound levels, distortion, delay, codec-type IP Network
