Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0037] The TCP protocol is link-oriented, and the TCP protocol is processed in the TOE system. A connection needs to be established before data transmission starts, and the protocol processing module responds to the last data when sending and receiving data. Disconnect at the end of the transfer. Since the speed of hardware processing protocols is much faster than that of software, there may be data accumulation at the interface of software and hardware, resulting in congestion problems. Especially when multiple ports establish TCP connections at the same time, the hardware cannot process dat...

Abstract

The present invention provides a data transmission method and device, wherein the method includes: obtaining the destination IP address and port number; configuring a handle identification number for the destination IP address and port number, and sending the handle identification number to TCP / IP accelerator board; perform data transmission with the TCP / IP accelerator board through the handle identification number. The possibility of congestion in the data transmission process is avoided through the above method, and hardware resources are saved, thereby improving the processing performance of the TCP / IP accelerator.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data transmission method and device. Background technique [0002] According to Thumb's law, about 1 Hertz of CPU (central processing unit) performance is required to transmit 1 bit of data. Therefore, with the emergence of Gigabit Ethernet and 10 Gigabit Ethernet, the consumption of CPU resources is increasing. In addition, since most operating systems are not real-time operating systems, the CPU is used as the main processing platform of the protocol stack, and its scheduling and cache delays are no longer applicable as the network bandwidth increases. For this reason, researchers have proposed the TCP / IP protocol offload engine TOE (TCP OffloadEngine, TCP offload engine) technology, that is, the processing of the TCP / IP protocol stack is transferred to the hardware accelerator for implementation, thereby reducing the utilization rate of the host CPU, and Improve transmis...
