TCP DATA TRANSMISSION METHOD, TCP OFFLOAD ENGINE, AND SYSTEM

摘要

Embodiments of the present invention provide a transmission control protocol TCP data transmission method, a TCP offload engine, and a system, which relate to the field of communications, and can reduce data migration between the TCP offload engine and a CPU, and at the same time reduce parsing work on data by the CPU, so as to achieve the effects of reducing resources of the CPU for processing TCP/IP data and reducing transmission delay. The method includes: a TCP offload engine receives TCP data sent by a remote device; performs TCP offloading on the TCP data; identifies the TCP offloaded data, and sends, according to an identification result, the TCP offloaded data to a CPU or a storage device corresponding to storage position information issued by the CPU. The embodiments of the present invention are applicable to TCP data transmission.

1. A transmission control protocol (TCP) data transmission method, comprising:
receiving, by a TCP offload engine, TCP data sent by a remote device; performing, by the TCP offload engine, TCP offloading on the TCP data to identify TCP offloaded data; and sending the TCP offloaded data to a central processing unit (CPU) or to a storage device corresponding to storage position information issued by the CPU.
