Increasing service demands on today's network servers can no longer
be satisfied by conventional TCP/IP protocol processing without
significant performance or scalability degradation. With
gigabit-per-second networking technologies, protocol and network
interrupt processing overheads can quickly saturate the host processor
at high loads, thus limiting the potential gain in network bandwidth.
The goal of this project is to develop an architecture for the
network subsystem that relies on offloading TCP/IP processing to
dedicated processors, nodes or intelligent devices. This architecture
should help to alleviate overheads resulting from network processing
and also eliminate negative effects of co-location of server
applications with computation intensive OS functions and network
protocols.

To reduce the impact of TCP overhead on the performance of the
server, we propose TCP Servers, a software
mechanism to offload TCP processing from the host to dedicated
processors, nodes, or intelligent network interfaces. We call the
dedicated processor/node which executes the TCP/IP processing, a TCP
server.
The TCP/IP processing is offloaded to the TCP server using
low-overhead, non-intrusive communication.
