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 invention discloses a data transmission method, an optimization device and a system, and belongs to the technical field of data transmission. The method comprises the steps that a data optimization device receives feedback information sent by a data scheduling device, and the feedback information is used for reflecting the scheduling condition of a to-be-scheduled data message by the data scheduling device and configuring a target bandwidth according to the feedback information, wherein the target bandwidth is a rated data volume sent to the data scheduling device by the data optimizationdevice in unit time; and based on the configured target bandwidth, sending an optimized to-be-scheduled data message to the data scheduling device, the optimized to-be-scheduled data message being a data message subjected to flow acceleration processing by the data optimization device. According to the invention, the utilization rate of the bandwidth is effectively improved, effective transmissionof other data messages can be ensured, and the flexibility of TCP-based data transmission is improved. This application is used for data transmission.

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 application 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 s...
