Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0052] When data transmission is based on the TCP protocol, when the network resources available in the transmission system (for example, network resources such as bandwidth or switching node cache) cannot meet the network resources required for data transmission within a certain transmission period, the performance of the network will decrease. It will get worse, that is, the network will be congested. In view of this, the congestion control method is generally adopted in the TCP protocol to solve this problem. The congestion control method realizes the control of the amount of data injected into the network by controlling the size of the congestion window, so as to avoid network congestion, and, in controlling the size of the co...

Abstract

The application discloses a data transmission method, optimization device and system, which belong to the technical field of data transmission. It includes: the data optimization device receives the feedback information sent by the data scheduling device, and the feedback information is used to reflect the scheduling situation of the data message to be scheduled by the data scheduling device; according to the feedback information, the target bandwidth is configured, and the target bandwidth is all The rated amount of data sent by the data optimization device to the data scheduling device per unit time; based on the configured target bandwidth, send the optimized data message to be scheduled to the data scheduling device, and the optimized data to be scheduled The message is a data message processed by the data optimization device for traffic acceleration. The application effectively improves the utilization rate of the bandwidth, and can ensure the effective transmission of other data messages, thereby improving the flexibility of data transmission based on TCP. This application is used for data transfer.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method, optimization device and system. Background technique [0002] Transmission Control Protocol (Transmission Control Protocol, TCP) is a connection-oriented, reliable and byte stream-based transport layer communication protocol. When data transmission is based on the TCP protocol, due to factors such as bandwidth limitation and signal attenuation, the transmitted data will experience packet loss and delay, which will reduce the throughput of the TCP connection for data transmission, resulting in high throughput. The data transfer of the app is affected. Wherein, the throughput rate of the TCP connection refers to an average transmission rate of data successfully transmitted through the TCP connection within a unit time. [0003] In related technologies, by filtering the data of high-throughput applications from the data to be sent, and...
