Jitendra Garg DGM(MPLS& IPTV) Testing IPTV Two areas of focus when testing IPTV Infrastructure Testing – verifying the capacity and behavior of the network and each network element Video Quality Testing – assessment of the end user Quality of Experience (QoE) Testing procedure: Benchmark each area separately Test video quality under varying loads at different points in the network Increase the number of Video Streams and Subscribers to cause the QoE to degrade –this creates a deployment benchmark for customers Jitendra Garg DGM(MPLS& IPTV)

Infrastructure Testing Bandwidth Can the infrastructure handle hundreds of channels? Channel zapping How fast can a user change channels? Channel validation Is the correct information being received? Benchmarking How do real servers compare to the Lab environment? Triple-Play What is the effect on Voice and Data? Jitendra Garg DGM(MPLS& IPTV)

Infrastructure Testing Infrastructure Testing Methodology: Bandwidth capacity to handle expected size and number of multicast streams Network and network element performance and scalability Vary subscriber profiles, background traffic and measure: Number of multicast streams supported % packet loss Maximum number of subscribers supported, etc. Channel change behavior Create profiles to emulate subscriber behaviors, background traffic and measure: Channel change (zapping) time Join failures Redundant joins Packet loss Join/leave latencies, etc Jitendra Garg DGM(MPLS& IPTV)

Jitendra Garg DGM(MPLS& IPTV) Technical Parameters Jitter : <10 msec (2 msec for HDTV) Packet loss : < 0.1 % (I-frame loss critical) Zap time : 2 to 3 seconds Latency : Critical For HDTV… 8 Mbps For SDTV… 2 Mbps Jitendra Garg DGM(MPLS& IPTV)
