FCC

Technical Advisory Committee

18 September 2002


Broadband way yesterday vs tomorrow l.jpg

1 cable modem/3 mo

568 user network

2400 Bps connectivity

$18,000 per unit

Data only

Luxury feature

1 cable modem/0.1 sec

100 million users

100,000,000 bps

Less than $10 per unit

Video, data, voice

Key element of life

Broadband Way(Yesterday vs. Tomorrow)

1988

2010

In North America, installing a cable modem every 8 seconds and a DSL modem every 16 seconds

Network Technologies

Applications

Industry

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

Other considerations: Native QoS ? Security ?

Over 60% in just the last 2 years

Focus on PCs for now, not Multimedia (yet)


Applications l.jpg

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)

Meter reading (bps)

Toggling a light switch (bps)

New stuff every day, and higher bandwidth


Bandwidth needs l.jpg
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 l.jpg
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

  • Ad Hoc Network

    • Consumer runs the home network

      • Finds their own services

  • Managed Network

    • Services

    • Network + Services

  • Efforts

  • Zeroconf

  • UPnP™

  • OSGi™

  • CableHome™

  • ITU SG 9

  • CEA R7.3 (VHN)

  • HAVi

  • BlueTooth™

  • Jini™

Differing Semantics, Consumer Choice


Group details l.jpg
Group Details

  • ZeroConf

    • no centralized configuration, management, or administration

  • UPnP™

    • IP and A/V services, on the home network

  • OSGi™

    • offering services over any IP network

  • CableHome™

    • IP and A/V, home network and access network services

  • BlueTooth™

    • IP home network services using BlueTooth wireless

  • VHN

    • CEA standards committee R7.4. Adopted UPnP + extensions

  • HAVi

    • audio/video home network services using IEEE1394

  • Jini™

    • Requires adopting JAVA as the implementation language
