Embedded IP
Raffi Krikorian
Building Internet0
• Traditional networking
hardware research focuses on
bigger and faster pipes
(Internet2)
• We focus on bit-dribbling
hardware
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)
Going really small
• Distributed scalable system -no central points of control
• Self organizing
• Growing
Building the small
things
• PIC microcontrollers
• Delayered TCP/IP stack and
HTTPd (3K code)
• RS-485 communication
What to do with all
of this?
• Embedded IP allows us to
build/learn/play with distributed
systems
• First test installation was in
Barcelona, moving towards
second
• CBA’s new home is first
permanent testbed
