Abstract

As part of an effort to accelerate server TCP/IP networking, Intel R&D has developed a software prototype that uses one of the intel xeon processors in a multiprocessor server as a packet processing engine (PPE). This prototype serves as a vehicle for empirical measurement and analysis of a highly programmable PPE that is closely tied to the server's core CPU and memory complex.
