Abstract: To alleviate the burden of CPU and improve system performance, a TCP Offload Engine(TOE) system based on Field Programmable Gate Array(FPGA) is designed and implemented. This TOE network adaptor adopts a hardware solution to implement some TCP protocol software dataflow processing, such as packet classification and TCP stream reassembly. Test results show that TOE network adaptor can greatly decline host’s CPU utilization.
