2 Over-the-Top Video Transport Les Wu April 2010

3 All Rights Reserved © Alcatel-Lucent 2009 3 | TIA Contribution | April 2010 1 P2P Captures

4 All Rights Reserved © Alcatel-Lucent 2009 4 | TIA Contribution | April 2010 P2P Capture Comparisons

5 All Rights Reserved © Alcatel-Lucent 2009 5 | TIA Contribution | April 2010 Contributed p2p

6 All Rights Reserved © Alcatel-Lucent 2009 6 | TIA Contribution | April 2010 Contributed p2p (15s integration)

7 All Rights Reserved © Alcatel-Lucent 2009 7 | TIA Contribution | April 2010 Voice Traffic

8 All Rights Reserved © Alcatel-Lucent 2009 8 | TIA Contribution | April 2010 2 TCP Delivery

9 All Rights Reserved © Alcatel-Lucent 2009 9 | TIA Contribution | April 2010 Bandwidth Utilization from TIA Model

10 All Rights Reserved © Alcatel-Lucent 2009 10 | TIA Contribution | April 2010 Identical YT-HD Views (5s average) 8-min HD view of Shuttle Landing Run twice from home and once from lab

11 All Rights Reserved © Alcatel-Lucent 2009 11 | TIA Contribution | April 2010 RTMP Capture – Out of the Box

12 All Rights Reserved © Alcatel-Lucent 2009 12 | TIA Contribution | April 2010 Network Utilization of NBCU Olympics Clip 1s bandwidth averaging from the wireshark capture TCP based transport Bandwidth utilization appears greedy  Initial bandwidth spike of 27.7 Mbit!  Avg bitrate of 2.4Mbit has much higher excursions

13 All Rights Reserved © Alcatel-Lucent 2009 13 | TIA Contribution | April 2010 3 Silverlight Lab Experiments

14 All Rights Reserved © Alcatel-Lucent 2009 14 | TIA Contribution | April 2010 Silverlight Lab Capture Scenario  Big Buck Bunny Encoded via MS Expression Encoder 1080p standard profile  VC-1, 10 bitrates from 230k up to 6Mbit  Pristine 1GB Lab Network  Unconstrained, 10Mbit, 6.5Mbit, 4.5Mbit Policing with Aune Box  Policing done with a 250,000 byte Commited Burst Size (CBS) Buffer Results:  Protocol appears greedy with massive bandwidth spikes  Even though 6Mbit claimed available, Silverlight did not appear to actually stream to that rate delivering 2-3 Mbit video!

15 All Rights Reserved © Alcatel-Lucent 2009 15 | TIA Contribution | April 2010 Unconstrained

16 All Rights Reserved © Alcatel-Lucent 2009 16 | TIA Contribution | April 2010 Constrained 10 Mbit

17 All Rights Reserved © Alcatel-Lucent 2009 17 | TIA Contribution | April 2010 Constrained 6.5 Mbit

18 All Rights Reserved © Alcatel-Lucent 2009 18 | TIA Contribution | April 2010 Constrained 4.5Mbit

19 All Rights Reserved © Alcatel-Lucent 2009 19 | TIA Contribution | April 2010 Comparisons Yellow: Streaming Bitrate Green: Frame Rate Red/Blue: Video Bitirate Ideal 4.5 Mbit 6.5 Mbit 10 Mbit
