Offloading the Transmission Control Protocol (TCP)/ Internet Protocol (IP) is a task that relieves the main processor from having to service interrupts to the kernel for protocol handling. High traffic networks nodes with a single processor interrupt the processor each time a packet is received. The networks consume main processor cycles by loading it with frame carriers. Performance is wasted on packet handling. By offloading, the CPU load is reduced leaving more CPU time for the application and socket layers.
