Abstract

The application discloses a data transmission method, device, storage medium and equipment, which belong to the field of cloud technology. The method includes: receiving data sent by a sending end in a current data transmission round; sending a response data packet for the data transmission round to the sending end; wherein, the response data packet includes a target field, the The target field is used to indicate the data packets received and the unreceived data packets at the receiving end within the data transmission round. In this application, the response data packet clearly indicates the data packets received by the receiving end and the unreceived data packets in the data transmission round, that is, the receiving end can indicate the arrival of the data packets in detail, and then the sending end The response data packet can clarify which data packets have arrived and which data packets have not arrived, which can well solve unexpected situations such as packet loss. This method of data transmission works better.

Description

technical field [0001] The present application relates to the field of cloud technology, and in particular to a data transmission method, device, storage medium and equipment. Background technique [0002] In the data communication based on TCP (Transmission Control Protocol, Transmission Control Protocol), the reliable transmission of data depends on the confirmation response mechanism. Among them, ACK (Acknowledge character, acknowledgment character) is a kind of transmission control character sent by the receiving end to the sending end in data communication, which is used to indicate that the data sent by the sending end has been confirmed to be received correctly. In other words, due to the unreliability of the communication process, emergencies such as data loss will inevitably occur in data communication. In order to solve these emergencies, TCP has designed an acknowledgment response mechanism, that is, the sending end sends data to the receiving end. , the receivin...
