  1. The state of home networks CSE481M: Home Networking Capstone March 30th, 2011

  2. Home networks are a success Broadband penetration (US) Revenue for networked devices (worldwide) Source: Home Networking Market Data, ABI Research, Nov 2010

  3. Home networks are a failure • High return rates despite no technical issues • 25% of routers are returned • Poor uptake for new technologies • Only 159K home automation controllers shipped worldwide in 2009 • Ample evidence of user frustration

  4. Home networks are a failure (indeed)

  5. Where did home networks come from? • Short answer: The Internet and the enterprise • Long answer: • Computer networks developed to support research • Came home using dial-up; went mainstream with WWW • Intra-home connectivity became widespread with wireless • Applications developed for the home and convergence with consumer electronics • Richer mechanisms (e.g., access control) developed for the enterprise environments

  6. An example home network

  7. But the home is different • No trained administrator • Heterogeneity • Applications • Devices • User preferences • Expectation of privacy

  8. Resulting friction: Technical Need for config and possibility of misconfig Mismatch between real and expected network Policy vs. mechanism

  9. Resulting friction: Human factors • Poor conceptual models • Need and poor support for personalization • Hurts debugging as well • Expectation of privacy

  10. Resulting friction: Economic • Multiple, competing stakeholders • Partitioned visibility and insight • Whose problem is it anyway? • Heterogeneity leads to high cost

  11. Implications for the future • Develop solutions customized for the home environment • No trained admin • Heterogeneity • Privacy • Work across areas of computer science
