1 cable modem/3 mo

568 user network

2400 Bps connectivity

$18,000 per unit

Data only

Key element of life

Broadband Way(Yesterday vs. Tomorrow)

1988

Efforts

  • Connections
    • Wired vs. wireless
      • Power line, phone line, dedicated line, wireless
    • Synchronous, asynchronous
  • Carry IP and MPEG
  • Some do it “better” than others
    • Faster throughput, Lower latency
    • Native QoS
    • More reliable
    • Easier to install
    • RF / electrical integrity
    • Wireless spectrum issues
  • Technology
  • IEEE 802.3
  • IEEE 802.11
  • HomePlug™
  • HomeRF™
  • HomePNA™
  • Bluetooth™
  • IEEE 1394
  • UWB
  • Etc.

Applications and the Marketplace will shake this out

Focus on PCs for now, not Multimedia (yet)

applications
Video Streaming (500 kbps – 5 Mbps)

Telemetry (up to 300 kbps)

Web Surfing/E-mail (up to 200 kbps)

Streaming (up to 200 kbps)

Fast-twitch games (up to 128 kbps)

Voice (up to 128 kbps)

New stuff every day, and higher bandwidth

bandwidth needs
Bandwidth Needs
  • Yesterday
    • low bandwidth
      • E.g., designed for 56 kbps dialup
    • Symmetric: email (no attachments)
    • Asymmetric: web browsing
  • Today
    • High bandwidth, moving toward symmetry
    • but mainly store and forward
      • digital images
      • Peer-to-peer
  • Tomorrow
    • Real-time streaming (controlled latency and jitter)
    • Prioritized

  • Average up/downstream data flow symmetry is 1.4
    • Data flow has been fairly stable since September 2001
  • Average individual user symmetry (independent of volume) is 4:1
  • 30% of users have more upstream than downstream use
  • Symmetry tends to increase as use increases
  • Data flow symmetry is skewed by big users
more on symmetry and traffic
More on Symmetry and Traffic
  • Traffic breakdown of a major ISP
    • Backbone traffic = 26 Gbps
    • 17 Gbps into homes, 9 Gbps out of homes
      • Symmetry = 1 : 1.8
        • 34% peer-to-peer
        • 27% web
        • 18% net news
        • 21% other
    • 50% of sub’s use only 5% of the bandwidth
    • Other 50% of sub’s use 95% of the bandwidth
