Problems solved by technology

But UDP is an unreliable protocol, that is to say, the client does not guarantee that the packet sent by the server to the client can be received.
In addition, some software such as firewalls will limit the flow of UDP connections. Therefore, when the UDP connection is used to transmit a lot of data, the flow will be limited, resulting in insufficient data transmission, increased dropout rate, and even interruption of data transmission.

Abstract

The invention discloses a data transmission method. The method includes the steps that a first data packet is sent to a data receiving device through a UDP link; at the overtime detection moment, whether the confirmation response of the first data packet returned by the data receiving device is received or not is detected; the confirmation response of the first data packet shows that the first data packet is received by the data receiving device; if it is detected that the confirmation response is still not received after exceeding preset duration, a request is made to the data receiving device, and a TCP link is established; a second data packet is sent to the data receiving device through the UDP link and the TCP link. The invention further discloses the other two data transmission methods, a data transmitting device, the data receiving device and a data transmission system. By means of the data transmission method, data transmission smoothness can be improved, and transmission quality is optimized.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data transmission method and system. Background technique [0002] In the prior art, instant messaging usually uses a TCP connection. For example, in online games, a TCP connection is usually used between the client and the server to communicate with each other, but if the client opens Thunder, or other machines on the same LAN as the client open Thunder or other download software, it will greatly affect the network. The network fluency of the game. According to actual statistical data, in online games, when TCP connections are used, the disconnection rate of the client is about 30%-40%. This is caused by TCP's active avoidance mechanism. The TCP active avoidance mechanism is specifically: after the first network abnormality (such as packet loss) is discovered at the network layer, the TCP mechanism will actively reduce its own network rate. For example, if the TCP pac...
