% Registration An Alternative to TOE: Intel I/O Acceleration
% [2]Register/Submit Chris Leech (christopher.leech@intel.com)
Intel's I/O Acceleration Technology is a combination of
network controller and server chipset features that
achieves increased networking performance, and still
makes use of the OS's native protocol stack. The first
generation of this technology will free up the CPU by
providing an asynchronous, low-cost copy mechanism, and
better CPU scaling via multiple transmit and receive
queues.
We will be describing the changes we implemented to
support these new capabilities, both to the network
driver and the network stack, as well as other design
choices considered. In addition, we will be presenting
data on the performance impact of each of these
elements, and the cumulative improvement obtained.
