TCP Offload
Engine (TOE)
The TCP/IP protocol suite is used to provide transport services for a wide
range of applications for the Internet, LAN, and for file transfer. The TCP
protocol is specifically designed to insure that data packets are delivered
error free and in the correct sequence from an application running a one
computer to the receiving application. The TCP protocol suite historically
has run on the host CPU, but with higher data rates, this consumes a very
high percentage of its resources while leaving little resources for the
applications. With the use of the Broadcom NetXtreme II adapter and the
TCP Offload Engine feature, the TCP/IP processing can be moved to
hardware, freeing the CPU for application processing and other higher
priority tasks
