  1. Telecommunications Industry Association TR-30.3/11-04-003 Austin, TX April 4-5, 2011

  2. Current Mobile Video Habits (Strategy Analytics) • Less than 50% users viewing video weekly • >37% over 3G/4G network • Significant proportion of video traffic is over-the-top.

  3. Progressive Download • Identical YT-HD Views (5s average) • 8:05 HD (720p) view of Shuttle Landing: http://www.youtube.com/watch?v=7rfmb3uuLE8 • Greedy client pulls as hard as it can on the network!

  4. Bandwidth Utilization

  5. Netflix @ Home • Netflix over 15Mbit/2Mbit Cable Service • Initial 50s · 10Mbit burst download to build up client buffer • ~2Mbit average bitrate • 50s · 8Mbit  200s excess buffer • Downloads very bursty (see detail)

  6. ipad – 1024x768 ipod – 480x320, 960x640 Netflix Streaming over 3G • VZW/Red ~1.2Mbit • TMOB/Blue 3Mbit adapting to 1Mbit • AT&T: No Joy

  7. Drive tests conducted for 3 networks over a common route Distinct differences in coverage and performance seen iperf throughput measurements also made These data can be used in lab emulation experiments A 3G Drive Tests www.sensorly.com

  8. Ideal LTE PDV Measurement • Single Sector, Single Radio, emulated packet core • 1350-byte ping responses with unloaded network with and without iperf loading

  9. 4G Mobile Network Architecture Video Server S6a S1-MME Gx Tx X2 S11 HSS MME eNodeB PCRF Internet S1-U S5/S8 SGi SGW Operator IP Network PGW eNodeB LTE Uu

  10. Sample Bitrate Structures 720x480i MPEG-2 MP/ML 6Mbit Avg DVD (9.5Mbit Peak) 720x480i H.264 Main:3.0 1.8Mbit re-encoded from DVD 424x240p H.264 baseline:2.1 690kbit Podcast 1920x1080i MPEG-2 17Mbit ATSC 576x320p H.264 baseline:3.0 800kbit iTouch4

  11. Linux Rate Shaping Initial Tests
