  1. Internet 0 Raffi Krikorian Center for Bits and Atoms

  2. An Internet of devices • Bringing IP to the leaf node • Devices are fundamentally different from general purpose computers • Computationally constrained • Small memory footprints • Extremely bandwidth limited

  3. The rules are different • Configuring and installing devices is harder than computers • Much higher density of devices/Many more devices

  4. Building a distributed system • No single “processor” running the system • Each device houses information pertinent to itself • data • pointers • threads • Inherent fault tolerance

  5. Current engineering • PIC microcontrollers • plenty of space for networking code • “black box” IP • just a few dollars • Cheap transports • RS-485 • powerline • ultrasonic

  6. One of CBA’s first contributions • Have preliminary prototypes • Has already left the building • Sun Microsystems has volunteered to chair a sister project to Java for Internet 0

  7. Routing • Software P2P systems do “layer 7 routing” • Gnutella • JXTA • Trying to get routing/naming to be an intrinsic part of the network (again)

  8. Central control vs. ad-hoc • Servers are bad! • Passive wired devices cannot handle full ad-hoc • Grand test problem - trying to emerge distributed router
