Practicality Intrudes
Vision:
The presence of a home network will enable creation of many new applications and services
Such as Home Information Management Services
Reality:
I encounter difficulty in simply adding devices and software to my home PC and in keeping the PC operating. Imagine life with a home network

The Real Topic of this Talk
Challenges of making home networks easy to install, use and maintain
Industry efforts to address this problem
Our approach to these issues
Home Information Management Services
An application that addresses an emerging need and illustrates how we think Home Networks should behave

What is a Home Network?
A “Home Network” connects consumer devices in the home to facilitate communications among the devices
STB Fixed Wireless Wireless Adapter Wireless Home LAN Media Access Gateway Existing Telephone Wiring Internal HPNA Printer Adapter Indoor CM/BTI Voice Adapter Outdoor CM/BTI Fax Voice Adapter No Adapter

Some Home Network Application Drivers
Technology advances make it practical
Small, low cost storage and computation
High bandwidth distribution
Evolution of MAC/PHY standards for the home
Wireless devices
Economical device sharing and control
Consolidation of display devices, and automation
Migration to lower cost IP based services
Voice, video and data
The Internet
Entertainment and multimedia
Multi-player gaming, video on demand
Services targeted to home consumers
Messaging, backup, e-commerce, remote sensing

Rosy Predictions
The home-networking equipment market is expected to grow from about $600 million this year to more than $5.7 billion by 2004 (Cahners In-Stat Group)
More than 12 million U.S. homeowners want to implement home-networking capabilities within the next year (Yankee Group)
Cahners In-Stat Group predicts annual sales of 30,000,000 residential gateway units for a total of $5 billion in 2005
But…
Widespread adoption requires substantial improvements in ease of use, security, and robust operation

Challenges
Accessible to normal humans
No 4-letter words
DHCP, RARP, ICMP, RSVP, IGMP, NAPT, SNMP, TFTP, MPLS…
Configuration and management; Inter-working
Possibly more than one connection to the Internet
Cable modem, xDSL, Fixed wireless, Ethernet over twisted pair (EFM), Fiber to the home (FTTH), Satellite, …
Variety of home interconnects
CAT5 Ethernet, wireless LAN (802.11x / proprietary), wireless PAN (Bluetooth), phone line (HPNA), power line (X10/CEbus, HomePlug), wired clusters (IEEE 1394, USB…)
Changing connectivity
Multiple device types and multiple devices of each type
Multiple protocol suites
Multiple servers of the same type

More Challenges
Fault diagnosis and maintenance
Detect failures and misconfiguration
Robust
Fault Tolerant
Local effects only
Self-stabilizing
Deterministic
Secure
Always connected to Internet means new risks
Control Access and operations on resources
Quality of Service (QoS)
Needed for applications that have minimum requirements on throughput, delay or delay variation for acceptable operation
Video, gaming

Current Solutions May Not Always Apply
A Home Network differs from an Enterprise Network
Cost sensitivity
IP address sharing leads to new problems
Scale
Many homes with few users in each
Many simple, specialized devices per user
No IT department

Industry Activities
IETF ZEROCONF
General, ad hoc formation of networks
Not specific to home
Residential Gateway approach
Designed by and for access providers (e.g. MSO)
CableLabs
CableHome
http://www.cablelabs.com/cablehome/specs/CH-SP-I01-020405.pdf
DSL Forum
Similar to CableHome approach

Observations on CableHome
Designed from a cable provider viewpoint
Aimed at delivering managed services from the MSO network to the home network
Example: focuses on protecting MSO rather than home
Architecture presumes a cable-modem based residential gateway
Won’t help with your home network if you don’t have a CableHome compliant residential gateway
Points to existing standards where applicable
IP-based

CableHome Architecture Home Gateway Cable Home Domain MODEM
Services
Management & Provisioning
Addressing & Forwarding
Quality of Service
Security
Access Network Home Network

CableHome Services
Remote service provisioning by MSO
Secure, remote management of gateway by MSO
SNMP proxy for managing devices in home
DHCP for IP address and parameter configuration
ICMP ping
UDP/TCP loopback/echo
NAT/NAPT
Mixed bridging/routing
DNS
CQoS (extension of PacketCable QoS)
Firewall (two-way)

Integrated Services Home Networking
Systems approach to unify home network and to provide coherence and ease of use
Home network management and maintenance
Naming and discovery of devices and services
Automated configuration
Infrastructure
Communications
Application development (middleware)
Security
Applications for the home
Evolutionary
Build on existing standards (e.g. CableHome)
Emphasize simplicity of approach
Minimize changes to devices
Leads to more server-based approach

Home Information Management
Information is created and collected rapidly at low cost
Digital photography, video clips, financial statistics, …
Need to protect, share, sort, classify and find data
Some data are more valuable than others. Data needs to be:
Classified with respect to value and other metrics
Protected from unauthorized disclosure
Shared with authorized principals
Protected against loss
Information is stored in a myriad physical devices some of which move. People would like to:
Attach devices (that store data) to network
Locate and retrieve data from these devices
Display data anywhere

Photograph Management 1
Find pictures on devices attached to home network
Automatically find and configure devices as they attach to network
Discover pictures on device
Index pictures for later retrieval by attributes
Analyze content automatically
Facial and shape recognition
Other attributes
Date, location, …

Photograph Management 2
Policy-based management
Protection and access control
Share with friends and family
Move/back-up
Access anywhere
Adapt content to display device
User annotation via different interfaces
Voice or text
QoS infrastructure

Conceptual Illustration Cheese
Connect and configure
Yes Is this George Washington? Home Network
Discover device and find pictures
Automatically index
User confirms and adds annotations
