Abstract

Embodiments of the present invention provide a transmission control protocol (TCP) data transmission method, TCP uninstallation engine, and system, which relate to the communications field, and can reduce data removal between TCP the uninstallation engine and a CPU, and at the same time reduce parsing work on data by a CPU, so as to achieve the effects of reducing resources for processing TCP/IP data of the CPU and reducing a transmission delay. The method comprises: a TCP uninstallation engine receiving TCP data sent by a remote device; performing TCP uninstallation on the TCP data; and identifying the data after TCP uninstallation, and sending the data after TCP uninstallation to a CPU or a storage device corresponding to storage position information delivered by the CPU according to the identification result. The embodiments of the present invention are applicable to TCP data transmission.

Description

technical field [0001] The invention relates to the communication field, in particular to a transmission control protocol TCP data transmission method, a TCP unloading engine and a system. Background technique [0002] Transmission Control Protocol and Internet Protocol (Transmission Control Protocol / Internet Protocol, referred to as TCP / IP) is the most basic communication protocol in the Internet. However, the traditional TCP / IP technology needs to occupy a large amount of central processing unit (Central Processing Unit, CPU for short) resources when processing network data transmission. This is because the processing of TCP data is mostly processed by software, that is, processed by the TCP / IP protocol stack running on the processor. The software processing mainly includes three aspects: protocol processing, interrupt processing, and data replication. Brings huge overhead to the system. [0003] In recent years, the growth of video traffic accounts for the main part of ...
