Data transmission method and system and storage medium

Abstract

The embodiment of the invention relates to a data transmission method and system and a storage medium. The method comprises the following steps: the client sends a data transmission request to the SIPserver, splits a data packet to be transmitted into a plurality of sub-data packets according to the splitting information, calls a plurality of threads to send the plurality of sub-data packets to the SIP server in parallel, the SIP server combinesthe plurality of sub-data packets according to the splitting information to generate a data packet to be transmitted, and sends the data packet to theservice serverr; when the client performs data transmission on the service server by adopting the HTTP protocol and the data transmission is blocked, the SIP server is adopted to assist in completingdata transmission between the client and the service server, and a data packet splitting and parallel sending mode is adopted, so that the data transmission efficiency is improved, the transmission time is saved, and the data transmission success rate is improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of data processing, in particular to a data transmission method, system and storage medium. Background technique [0002] In the network layering, the Hyper Text Transfer Protocol (HTTP) protocol is a protocol based on the Transmission Control Protocol (TCP), and any request using the HTTP protocol at the bottom layer is carried out through the TCP protocol. When the client sends an HTTP request to the server, it needs to establish a TCP connection with the server first. The TCP protocol is responsible for providing a reliable abstraction layer over the unreliable transmission channel, hiding most of the complex performance of network communication from the application layer. Such as packet loss retransmission, on-demand transmission, congestion control and avoidance, data integrity, etc. Using TCP data stream can ensure that all bytes sent can be received completely and ensure the order.

Problems solved by technology

[0003] However, when the TCP protocol is used for data transmission, time consumption is not taken into account, which brings challenges to network interaction performance, especially in scenarios such as instant messaging or file uploading, instant messaging based on TCP protocol will lead to poor network conditions When users send and receive messages, the delay is too high, and the file upload is based on the TCP protocol, which will lead to slow upload speed and low success rate in weak network scenarios
