%  [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.
