  • The Evolution of Broadband from Coverage to Quality

    1. The Evolution of Broadband: From Coverage to Quality Robert Pepper Vice President Global Technology Policy 3 November 2008
    2. Four Stages of National Broadband Discussion <ul><li>Availability/Coverage (supply) </li></ul><ul><li>Adoption (demand) </li></ul><ul><li>“ Speed” </li></ul><ul><li>Quality </li></ul>
    3. Communications: From telephony to connectivity/broadband Networks: the Fourth Essential Infrastructure Transport IP Networks Energy ( Power ) Water
    4. What we all want <ul><li>Build on the success of the Internet </li></ul><ul><li>Ubiquitous broadband </li></ul><ul><li>Faster robust broadband networks </li></ul><ul><li>New innovative applications </li></ul><ul><li>Consumer/citizen benefits </li></ul><ul><li>Investment in networks and applications </li></ul>
    5. Growing Demand
    6. The Consumer in Control and Driving Demand Entire Internet Traffic Only 20 Homes 2010 “ By the year 2010… bandwidth for 20 homes will generate more traffic than entire Internet in 1995” 1995 Source: Cisco estimates, Ovum, Gartner, IDC, Merrill Lynch, MRG, MPA, Public company data
    7. Impact of Video on Internet Traffic 41% CAGR 2007-2012 Source: Cisco Visual Networking Index – Forecast, 2007-2012 GROWTH OF GLOBAL CONSUMER INTERNET TRAFFIC MIX 0 10,000 20,000 2005 2006 2007 2008 2009 2010 2011 2012 PB/month Internet Video to TV Internet Video to PC VoIP Video Communications Gaming P2P Web/Data
    8. [Gbps] Efforts for Grasping Current Status of Internet Traffic in Japan , MIC Est. download traffic of broadband users in Japan Monthly average of daily traffic of Broadband customers (ADSL/CATV/FTTH) of major ISPs in Japan (ref.1) Monthly average of daily peak traffic exchanged at major IXs in Japan (ref.2) Monthly average of daily traffic exchanged at major IXs in Japan IP traffic in Japan grew 2.5 times in 3 years to estimated 812.9Gbps in Nov 2007
    9. Heavy Users Dominate Traffic
    10. Traffic Consumption Among Residential Broadband Users -- 10,000-fold variation Source : 1% 5% 20% 50% 1 TB/Mo Avg = 8GB/Mo = 25Kbit/sec 1% => 225+ GB/Month 5% => 60+ GB/Month 20% => 7,5+ GB/Month 50% => 1+ GB/Month 90% Users are under the Avg
    11. Dimensions of Broadband: Quality Matters
    12. Dimensions of Broadband <ul><li>Bandwidth—”speed” </li></ul><ul><li>Latency </li></ul><ul><li>Jitter </li></ul><ul><li>Symmetry </li></ul><ul><li>Bursting </li></ul><ul><li>Other… </li></ul>
    13. Not All Bits Are Created Equal “Speed” and Latency Bandwidth Low High High Low Telepresence Voice HD-IPTV Sensitive to Latency Streaming Audio Gaming (LD) Gaming (HD) Email Download Video Streaming Video
