## 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

- 1988

- 2010

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

## Home NetworkingThree Dimensions

## 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 802.3
- IEEE 802.11
- HomePlugTM
- HomeRFTM
- HomePNATM
- BluetoothTM
- IEEE 1394
- UWB
- Etc.

**Applications and the Marketplace will shake this out**

## 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/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**

- _Applications_
- web
- email
- calendar
- games
- audio
- video
- voice
- home automation
- home security

## 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

## Gross Traffic is Nearly Symmetric

- 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

- 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
- UPnPTM
- OSGiTM
- CableHomeTM
- ITU SG 9
- CEA R7.3 (VHN)
- HAVi
- BlueToothTM
- JiniTM

**Differing Semantics, Consumer Choice**

## Group Details

- ZeroConf
- no centralized configuration, management, or administration
- UPnPTM
- IP and A/V services, on the home network
- OSGiTM
- offering services over any IP network
- CableHomeTM
- IP and A/V, home network and access network services
- BlueToothTM
- IP home network services using BlueTooth wireless
- VHN
- CEA standards committee R7.4.  Adopted UPnP + extensions
- HAVi
- audio/video home network services using IEEE1394
- JiniTM
- 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

## ITU J.191 Network - enabling services 

**Access Network**
**+ **
**service provider**
**+****Internet**

**10B-T**

**ITU J.191 Network**** - ****enabling services **

- DHCP, DNS, NAT, Firewall, etc. configured by service provider

**1394**

**Power line**

**Phone line**

## ZeroConf Network - enabling IP networks

**10B-T**

**ZeroConf Network**** - enabling IP**** networks**

**1394**

**Power line**

**Phone line**

**Internet**

- Simple Ethernet      switch configured by user
