Home Networking prepared for FCC Technical Advisory Committee 18 September 2002

Broadband Way (Yesterday vs. Tomorrow) 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 In North America, installing a cable modem every 8 seconds and a DSL modem every 16 seconds

Home Networking Three Dimensions Applications Industry Efforts Network Technologies

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 –IEEE –HomePlug™ –HomeRF™ –HomePNA™ –Bluetooth™ –IEEE 1394 –UWB –Etc. Applications and the Marketplace will shake this out Applications Industry Efforts Network Technologies

Technology Survey Other considerations: Native QoS ? Security ?

Length of Time Networked (n=778) © Parks Associates 2001 Focus on PCs for now, not Multimedia (yet) Over 60% in just the last 2 years

Applications Video Streaming (500 kbps – 5 Mbps) Telemetry (up to 300 kbps) Web Surfing/ (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 Applications –web – –calendar –games –audio –video –voice –home automation –home security Applications Industry Efforts Network Technologies

Bandwidth Needs Yesterday –low bandwidth E.g., designed for 56 kbps dialup –Symmetric: (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

Gross Traffic is Nearly Symmetric Average up/downstream data flow symmetry is 1.4 –Data flow has been fairly stable since September 2001 Symmetry May-01Jun-01Jul-01Aug-01 Sep-01 Symmetry 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 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 Nationwide footprint – August 2002

Industry Efforts Ad Hoc Network –Consumer runs the home network Finds their own services Managed Network –Network –Services –Network + Services Efforts –Zeroconf –UPnP™ –OSGi™ –CableHome™ –ITU SG 9 –CEA R7.3 (VHN) –HAVi –BlueTooth™ –Jini™ Differing Semantics, Consumer Choice Applications Industry Efforts Network Technologies

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

Compare/contrast ITU Study Group 9 –ITU J.191 (Draft) Managed networking Basic Residential Gateway (centralized data store) –DHCP, DNS, NAT, Firewall, etc. IETF Zero Configuration Working Group –ad hoc networking –No centralized servers or data stores

Access Network + service provider + Internet X.10 analog 10B-T ITU J.191 Network - enabling services DHCP, DNS, NAT, Firewall, etc. configured by service provider 1394 Power line Phone line

10B-T ZeroConf Network - enabling IP networks 1394 Power line Phone line Internet Simple Ethernet switch configured by user
