Embodiment Construction

[0031] see figure 1 , provides an embodiment of a network transmission system, including a sending end and a receiving end, when the sending end needs to send data content to the receiving end, first, it needs to obtain the data to be sent by the sending end, that is, obtain the data content to be sent. Then, when the content of the data to be sent needs to be sent, it needs to be packaged, that is, a data header corresponding to the content of the data to be sent needs to be initialized to represent the data type, the serial number of the data to be sent, and the data to be transmitted. The data length of the data to be sent.

[0032] Then, according to the data header and the content of the data to be sent, the data to be sent is generated. When the data to be sent is sent, in order to improve the sending efficiency, the data to be sent is sent to the receiving end through the UDP protocol transmission mode. In order to reduce the packet loss rate and improve transmission ...

Abstract

The invention relates to a network transmission method and device based on a UDP (User Datagram Protocol). In order to improve the transmission efficiency and reduce the transmission delay, data to be transmitted is transmitted to a receiving end in a UDP transmission manner; when an acknowledgment data head transmitted by the receiving end according to the content of the data to be transmitted is not received, the receiving may not receive the data to be transmitted; and in order to ensure the transmission reliability, the data to be transmitted is retransmitted to the receiving end at preset time intervals. Further provided are a network transmission method and device. After the data to be transmitted is received, the acknowledgment data head carrying a data number is also transmitted to the receiving end to accurately notify which data to be transmitted a transmitting end has received, and an indication for acknowledging reception is provided to the transmitting end, so that the transmission reliability is ensured; and in order to improve the transmission efficiency, the acknowledgment data head is transmitted to the transmitting end in the UDP transmission manner, so that both the transmission reliability and the transmission efficiency are ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a UDP-based network transmission method and device, and a network transmission method and device. Background technique [0002] In network communication, UDP (User Datagram Protocol) transmission mode and TCP (Transmission Control Protocol) transmission mode are commonly used. The UDP protocol is a non-connection protocol. The sending end and the receiving end do not establish a connection before transmitting data. After obtaining the data to be sent, they try their best to deliver the data, and the receiving end can release it after receiving the transmitted data. In the queue, reliable delivery is not guaranteed, and there is no retransmission mechanism in the TCP protocol. When using the UDP protocol to communicate, the size of the transmitted data packet is small, so the resources required during the transmission process are less, the data transmission is out o...
