Problems solved by technology

Due to the instability of the mobile network (poor signal, network switching, etc.), the network delay is high and the packet loss rate is high, or the application needs to be temporarily closed due to the power saving of the mobile device, and the connection needs to be re-established when the application is started. When the network is unstable and the application is restarted by the TCP protocol, the data transmission speed is relatively slow, the data packet loss rate is high, and the reconnection speed of the network connection is slow. very slow

Abstract

The invention provides a data transmission apparatus and method of a client and a data transmission apparatus and method of a server, and relates to the field of Internet communication. The data transmission apparatus of the client comprises a splitting unit used for splitting an HTTP request to form a plurality of data sub-packets; a protocol unit used for sending the plurality of data sub-packets to the server through a UDP; an analysis unit used for obtaining and performing meta-analysis on reception acknowledgement messages corresponding to the data sub-packets and transmitted by the server to find data sub-packets having no reception acknowledgement in the plurality of data sub-packets; a retransmission unit used for retransmitting the data sub-packets having no reception acknowledgement to the server until determining the fact that the server receives all data sub-packets; and a first receiving unit used for receiving HTTP response data transmitted by the server. By adoption of the technical scheme provided by the invention, the problem of too slow webpage request resulting from the instability of a network and the power saving of a mobile phone in a mobile network can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of Internet communication, in particular, to a client data transmission device, a client data transmission method, a server data transmission device and a server data transmission method. Background technique [0002] With the rapid development of the mobile Internet, there are more and more applications on mobile devices such as mobile phones and tablets. Most applications interact with servers using the HTTP protocol. The existing HTTP protocol is basically implemented based on TCP. Due to the instability of the mobile network (poor signal, network switching, etc.), the network delay is high and the packet loss rate is high, or the application needs to be temporarily closed due to the power saving of the mobile device, and the connection needs to be re-established when the application is started. When the network is unstable and the application is restarted by the TCP protocol, the data transmissio...
