  20. 20. Testing IPTV <ul><li>Two areas of focus when testing IPTV </li></ul><ul><ul><li>Infrastructure Testing – verifying the capacity and behavior of the network and each network element </li></ul></ul><ul><ul><li>Video Quality Testing – assessment of the end user Quality of Experience (QoE) </li></ul></ul><ul><li>Testing procedure: </li></ul><ul><ul><li>Benchmark each area separately </li></ul></ul><ul><ul><li>Test video quality under varying loads at different points in the network </li></ul></ul><ul><ul><li>Increase the number of Video Streams and Subscribers to cause the QoE to degrade –this creates a deployment benchmark for customers </li></ul></ul>
  21. 21. Infrastructure Testing <ul><li>Bandwidth </li></ul><ul><ul><li>Can the infrastructure handle hundreds of channels? </li></ul></ul><ul><li>Channel zapping </li></ul><ul><ul><li>How fast can a user change channels? </li></ul></ul><ul><li>Channel validation </li></ul><ul><ul><li>Is the correct information being received? </li></ul></ul><ul><li>Benchmarking </li></ul><ul><ul><li>How do real servers compare to the Lab environment? </li></ul></ul><ul><li>Triple-Play </li></ul><ul><ul><li>What is the effect on Voice and Data? </li></ul></ul>
  22. 22. Infrastructure Testing <ul><li>Infrastructure Testing Methodology: </li></ul><ul><ul><li>Bandwidth capacity to handle expected size and number of multicast streams </li></ul></ul><ul><ul><li>Network and network element performance and scalability </li></ul></ul><ul><ul><ul><li>Vary subscriber profiles, background traffic and measure: </li></ul></ul></ul><ul><ul><ul><ul><li>Number of multicast streams supported </li></ul></ul></ul></ul><ul><ul><ul><ul><li>% packet loss </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Maximum number of subscribers supported, etc. </li></ul></ul></ul></ul><ul><ul><li>Channel change behavior </li></ul></ul><ul><ul><ul><li>Create profiles to emulate subscriber behaviors, background traffic and measure: </li></ul></ul></ul><ul><ul><ul><ul><li>Channel change (zapping) time </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Join failures </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Redundant joins </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Packet loss </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Join/leave latencies, etc </li></ul></ul></ul></ul>
