The 21st Century Internet
After twenty years, the "S-curve" of building out the wired internet with hundreds of
millions of PCs as its end points is flattening out, with corresponding lowering of the
growth rates of the major suppliers of that global infrastructure. At the same time,
several new "S-curves" are reaching their steep slope as ubiquitous computing
begins to sweep the planet. Leading this will be a vast expansion in heterogeneous
end-points to a new wireless internet, moving IP throughout the physical world.
Billions of internet connected cell phones, embedded processors, hand held
devices, sensors, and actuators will lead to radical new applications. The resulting
vast increase in data streams, augmented by the advent of mass market broadband
to homes and businesses, will drive the backbone of the internet to a pure optical
lambda-switched network of tremendous capacity. Finally, peer-to-peer computing
and storage will increasingly provide a vast untapped capability to power this
emergent planetary computer. I will describe how the newly formed Cal-(IT)2
Institute is organizing research in each of these areas. Large scale "Laboratories for
Living in the Future" are being designed, some of which provide opportunities for
collaboration with Purdue faculty.
