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

3 GAH 5/23/02

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

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

6 GAH 5/23/02

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

7 GAH 5/23/02

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

8 GAH 5/23/02

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

9 GAH 5/23/02

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

10 GAH 5/23/02

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

11 GAH 5/23/02

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 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)

14 GAH 5/23/02

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

15 GAH 5/23/02

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

16 GAH 5/23/02

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, …

17 GAH 5/23/02

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
