Problems solved by technology

[0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: (1) Although the reliability of message transmission based on the TCP protocol is high, the time required for its transmission and system hardware resources are all required high, and the transmission low efficiency
For example, before transmitting data, it is necessary to establish a connection first, which consumes a certain amount of time, and in the process of data transmission, the confirmation mechanism, retransmission mechanism, and congestion control mechanism will consume a lot of time; in addition, it is necessary to maintain on each device All transmission connections occupy more hardware resources such as CPU and memory of the system
(2) Although the UDP protocol-based message transmission has high transmission efficiency, its transmission reliability is poor, and it is inconvenient to apply to application scenarios that have strict requirements on data accuracy

Abstract

The embodiment of the invention discloses a message transmission device, equipment and method and a storage medium. The method comprises the steps: receiving and analyzing a current transmission message based on a user datagram protocol, obtaining a current message identifier in a current message header field of the current transmission message, and arranging the message header field behind a user datagram protocol header field; judging whether the current message identifier is continuous or not according to the current message identifier and a historical message identifier of a historical transmission message received before the current transmission message; and if not, determining the identifier of the message to be retransmitted according to the current message identifier, generating aretransmission confirmation message according to the identifier of the message to be retransmitted, and sending the retransmission confirmation message to the message sending end, so that the messagesending end retransmits each subsequent transmission message starting from the identifier of the message to be retransmitted according to the retransmission confirmation message. According to the technical scheme, the message data can be efficiently and reliably transmitted.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a message transmission device, equipment, method and storage medium. Background technique [0002] In a traditional Ethernet network, the Transmission Control Protocol (TCP) is connection-oriented. It ensures the reliability of message data transmission through confirmation mechanism, retransmission mechanism, sliding window and congestion control mechanism, that is, error-free. Not lost, not repeated. Unlike the TCP protocol, the User Datagram Protocol (UDP) is connectionless. It does not need to establish a connection before sending data, and it does not have a complex mechanism similar to the TCP protocol, so the data transmission efficiency is higher. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: (1) Although the reliability of message transmission based on...
