Description

Method and device for transmitting data Technical Field The embodiment of the invention relates to the field of communication, in particular to a method and a device for transmitting data. Background When a transmission control protocol (Transmission Control Protocol, TCP for short) and a user datagram protocol (User Datagram Protocol, UDP for short) face large transmission tasks, the TCP is used as a reliable transmission protocol, and can efficiently realize complete data transmission under the condition of stable network links, but in a weak network environment, the congestion control and accumulated response mechanisms of the TCP can lead to the reduction of transmission throughput due to higher packet loss rate of network transmission, so that the performance of the TCP in the network environment is greatly reduced. The transmission rate of UDP is faster than that of TCP in a weak network environment, but UDP is unreliable, and problems such as data loss, repetition, and disorder may occur. TCP transport and UDP transport each have advantages and disadvantages for different network transport scenarios. In a Time-varying network environment such as Round-Trip Time (RTT) and packet loss rate, which are oriented to the network, if a single transmission protocol is adopted, there are corresponding drawbacks, and a problem of data transmission errors occurs. There is currently no effective solution to the above problems.
