Problems solved by technology

[0003] The current communication base station is relatively weak in the data transmission processing of the TCP protocol. During the data transmission process, sometimes a set of TCP data packets is repeated multiple times, but the communication base station does not deeply analyze the repetition when transmitting data through the TCP protocol. Responding to multiple urgent data, so that during the data transmission process, because the emergency transmission degree of the urgent data cannot be judged, the other data is still transmitted according to the normal sending queue, and then the urgent data is transmitted, resulting in the urgent data transmission. Delay, which affects the timely upload of emergency data that has been repeatedly answered by the communication base station

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] like figure 1 It is a schematic flow chart of the TCP transmission method in an embodiment, and the TCP transmission method of figure comprises the following steps:

[0033] S11: Obtain the message confirmation number of the TCP response message received through the network side;

[0034] S12: Obtain the latest confirmation number of the server;

[0035] S13: If the message confirmation number is equal to the latest confirmation number of the server, increase the repeated response count value of the TCP response message;

[0036] S14: If the repeated response count value is equal to the p...

Abstract

The invention provides a TCP (Transmission Control Protocol) transmission method and device. A message acknowledgement number of a TCP response message received by a network side and a newest acknowledgement number of a server are obtained; a relation between the message acknowledgement number of the TCP response message and the newest acknowledgement number of the server are judged; if the message acknowledgement number is equal to the newest acknowledgement number of the server, a repeat response count value of the TCP response message is increased; if the repeat response count value is equal to a preset threshold value, a sending priority of a TCP data message corresponding to the TCP response message in a local cache is improved; it indicates that the TCP data message corresponding to the TCP response message is urgent data needing to be uploaded to the network side again; the sending priority of the urgent data is improved through a base station; and the TCP data message is transmitted preferentially, so the TCP data message is transmitted timely.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a TCP transmission method and device. Background technique [0002] With the rapid development of communication technology, users have increasingly high requirements for the timeliness of data transmission, and data transmission cannot be separated from the TCP (Transmission Control Protocol, Transmission Control Protocol) protocol at the transport layer in the communication protocol. [0003] The current communication base station is relatively weak in the data transmission processing of the TCP protocol. During the data transmission process, sometimes a set of TCP data packets is repeated multiple times, but the communication base station does not deeply analyze the repetition when transmitting data through the TCP protocol. Responding to multiple urgent data, so that during the data transmission process, because the emergency transmission degree of the urgent dat...
