  • 1. Implementing Home Networking For 1999/2000 PCs Mark A. Carpenter Director Communications And Home Connectivity Compaq Computer Corporation
  • 2. Topics
    • Understanding today’s consumer needs
      • Defining opportunities for the PC industry
    • Elements for success
      • Technical, marketing, support
    • Hardware design considerations
      • For PC-based broadband, network media, and Internet sharing
    • What comes next?
  • 3. What Consumers Are Demanding Today
    • Engaging Internet content and services throughout their home
      • At faster than 56K speeds
    • Peripheral sharing between different PCs
      • Printers, files
    “ I like the Internet sharing so I don’t have to get a divorce. You know, we’re killing each other [over access].” - Houston focus group respondent
  • 4. Consumers Demand Broadband
    • Internet has become #1 reason for new PC purchase
    • Internet-based from stand-alone PC activities
    • Current speeds limit usefulness
    “ Web Lifestyle”: personalized information and entertainment driving Home PC demand Percent PC-buyers cite each of the top-6 reasons for purchase as “very important” in national survey (Forrester Research, 9/98) 80% are willing to pay for high-speed access (Parks Associates Survey, 10/98)
    • $39-$49/month target acceptable
    • High-speed access: key enabler to fully integrate into home lifestyle
    • Truly useful higher speed Internet requires new digital infrastructure
  • 5. Consumers Demand Sharing
    • 12-15 million multiple PC families today, worldwide *
      • Annual growth rate of about 30% = 25+ million by 2001!
    • Home Internet access mostly during evenings and weekends
      • When family members are home together
      • Creates need for shared access in multiple PC homes
    • Today’s solutions for Internet access conflict
      • Multiple phone lines and ISP accounts
      • Time sharing with single line and account
    • Broadband complicates the contention problem
      • Cable and full rate ADSL drops accessible to only one machine
      • Splitterless ADSL (G.Lite) requires multiple modems
        • Like normal modems, doesn’t resolve contention
    Tangible consumer needs are here now. Fortunately, so are the home networking technologies to meet them * Source: Dataquest, Oct. ’98

  • 12. Standard Broadband PC integration will drive proliferation
    • Standard technologies ramping up in 1999
      • G.Lite: splitter-less ADSL, up to 1.5 Mbps downstream
        • Lowest support option
      • G.DMT: splitter-based ADSL, up to six Mbps downstream
        • Requires phone company installation
      • Cable modem (DOCSIS)
    • Internal partitioning options, e.g., on PCI
      • DSL only modem: G.Lite, G.DMT, or both
      • DSL + V.90 modem
      • DSL/V.90 modem + phone line network
    • Preferred external connection: USB
      • For Plug and Play installation and configuration
      • 10baseT will require more configuration support
  • 13. Standard Phoneline Networks Proven technology available now
    • Cost effective: PC integration for $25 or less
      • Retail adapters < $50 per node
    • Familiar user model and technology
      • Most PCs already near phone jacks
      • Adding phone jacks is common practice, inexpensive
    • HomePNA standard in place, with future roadmap
      • Certified products guaranteed to interoperate
        • Logo established as “Seal of Approval”
      • Charter for backward compatibility
    • Proven to work, widely tested geographically
      • See http://www.HomePNA.org for whitepaper
    • Complements future wireless and powerline standards
  • 14. Home Phoneline Network Alliance First home connectivity cornerstone
    • 1998 accomplishments
      • Announced formation June 22, 1998, 11 Founding Members
      • Increased membership to nearly four times size since incorporation (September 1998)
      • Endorsed, field tested, and solidified base 1 Mbit/s technology
      • Published HomePNA V1.0 specification
      • Established Independent Interoperability and Certification test lab (CIC PlugLab)
    • 1999 objectives
      • Establish 10 Mbit/s home phoneline networking specification
      • Continue membership growth and engagement
      • Increase public awareness of home phoneline networking options
  • 15. Home Phoneline Network Alliance Field Test Introduction
    • HomePNA Field Test Overview
      • 500 Homes tested 9/98-11/98
      • North East, North West, Mid-West, Southwest, West Coast
      • Single family, Multi-Family, 90+ yrs old and newer dwellings
      • Field test units implemented HomePNA Phy
      • 6 hour duration, packet send/receive loop
      • Primarily targetted 6pm-midnight
        • Prime Time for activity in the home and projected for home network use
    • Measurement Criteria and Baseline Measures
      • Selected based on direct relevance to Consumer Experience
        • Maintain Network Link
        • Packet Error Rate
      • Based on measurements on a TCP/IP over Ethernet Link
        • 1% or less PER translates into no noticeable degradation (900kbps at the application level) and robust link
        • less than 10% PER translates into up to 40% degradation (550kbps+ at the application level) and robust link
        • 10% or greater PER translates into unacceptable performance characteristics
  • 16. Home Phoneline Network Alliance Field Test Results
    • 98%+ Homes Successfully Passed
        • 88% of homes reported 1% PER or less and maintained Link
        • >10% of homes ran with less than 10% PER and maintained Link
        • <2% of homes ran with 10% or greater PER
    • Homes with >1% PER were analyzed
      • Root Cause
        • Induced noise directly from telephony devices attached very near the HomePNA test unit or via coupling of AC line through powered telephony devices
        • Signal Attenuation theorized as attenuation due to wire taps
      • Both problems eliminated by introducing low pass filter between offending device and wall outlet
        • Frequency to be filtered out is >600Khz
        • Covers both voice band (V.90) through G.Lite
    • Other observed interactions - low pass filter resolves
      • Few reports of audible hiss in home telephones
      • Some models of V.90 modems experience performance degradation when sharing same wall outlet with HomePNA device
  • 17. Implementing HomePNA
    • On system board
      • Requires silicon, magnetics, and RJ-11 connector
      • Lowers cost, keeps slot free
    • On PCI or Cardbus adapter
      • Options: stand-alone, 10baseT combo, V.90 combo
      • Avoids system board homologation
      • Easier to isolate signals from system board and power supply noise
      • Combo 10baseT card can use existing MAC
      • Frees system board space, but uses slot
    • Use shared RJ-11 port with modem
      • Multiple ports a usability problem
      • Reduces connector space requirement
  • 18. Standard Internet Sharing Arriving in Windows releases this year
    • Microsoft Internet Connection Sharing (ICS):
      • Network Address Translation (NAT) based
        • Most efficient method for simple translation
      • Standard address allocation
        • DHCP services for connected networks
      • Standard name resolution
        • DNS services
      • Supports Windows and non-Windows clients
        • Compatible with any IP attached device
  • 19. Adding To Internet Sharing Building value-add applications

      • Leverage ICS APIs
      • Complement and enhance OSR functionality
        • Remote monitoring/control of Internet Session
        • Automated resource sharing
        • Monitoring of Internet traffic
    • Set specific guidelines for your ISVs
      • Requires well behaved applications
        • Avoid reserving IP ports
        • Avoid using client IP address in application flows
