  1. Building Embedded IP Raffi Krikorian Physics and Media

  2. Building Internet0 • Traditional networking hardware research focuses on bigger and faster pipes (Internet2) • We focus on bit-dribbling hardware

  3. Bridging the bandwidth divide • Bringing IP to the leaf node • Revisiting hardware transports and redesigning logical transports • Cheap, low bandwidth IP (a level below Ethernet)

  4. Going really small • Distributed scalable system – no central point of control/servers are “bad” • Devices own their data and own their threads • Self organizing • Growing

  5. Building the first embodiment of small things • RS-485 communication • mature industrial practice • no active joints • media access costs pennies • PIC microcontrollers • built in UARTs • plenty of space for networking code • just a few dollars

  6. Building more small things • Different physical transports • DSSS over powerlines • Wireless RF • Ultrasonic • Revisiting old transports – slowing them down makes them a lot more accessible

  7. Cramming bits is nothing new • “Delayered” software stacks • ARP, IP, ICMP, UDP, TCP – IPv4 compliant in 2K code • HTTPd 0.9 server – 1K code

  8. Naming, Classifying, Communication • IDs for each device – unified or multiple • For today, use Zeroconf – sub-DHCP • For tomorrow, possibly use IPv6 as the unique address through mini-routing? • Schema for identifying devices • Communication standards

  9. Programming and Coordinating a mass of devices • Programming arbitrary massively parallel distributed systems is hard, building simple ones is easier • These systems exhibit • Scale complexity • Interaction complexity • Minimal resources • Spatial relations

  10. Building higher level systems • Make it easy to cause complex behavior to occur • “Google-like” services • Hive • JXTA • Make it simple for complex behavior to emerge

  11. How do you test all of this? • First test installation was in Barcelona, moving towards second • … • CBA’s new home is first permanent testbed
