Problems solved by technology

[0004] (1) The connection is suddenly banned: due to the transmission control protocol’s data sending rate is too fast or the transmission bandwidth is relatively large, some infrastructure punishment measures in the transmission link are triggered, resulting in this connection being banned and data transmission interrupted
[0005] (2) The cost of disconnection reconnection and breakpoint resume transmission through the application layer is relatively high: the recovery technology of conventional means is relatively complicated, and there are restrictions on the application of the technology, and recovery is not possible in all cases

Embodiment 1

[0058] The present invention provides a data transmission method based on dynamic port switching, such as figure 1 As shown, the following steps are included: S101, the sending end and the receiving end establish a connection including the first source port, and then the sending end sets the second source port; S102, the sending end sends a message to the receiving end through the first source port; S103, When the connection between the sending end and the receiving end is prohibited, the sending end establishes a connection with the receiving end through the second source port and sends a message.

[0059] Specifically, such as figure 2 Shown:

[0060]In step S201, the sending end establishes a connection with the receiving end through the transmission control protocol (TCP). The sending end and the receiving end trigger the transmission control three-way handshake mechanism. When the transmission control three-way handshake is successful, a transmission control quadruple ...

Embodiment 2

[0075] The present invention also provides a data transmission system based on dynamic port switching, such as Figure 4 As shown, the sending end 100 and the receiving end 200 are included, and the sending end 100 and the receiving end 200 are connected through transmission control protocol.

[0076] specific,

[0077] The sending end 100 includes: a first transceiver module 101 and a port backup module 102 .

[0078] The receiving end 200 includes: a second transceiver module 201 .

[0079] The port backup module 102 is used to set the backup source port at the sending end 100, and to switch the source port; Reply message; the second transceiver module 201 is connected to the first transceiver module 101 for receiving the message sent by the sender 100 and sending a reply message to the sender 100 .

[0080] Such as Figure 5 As shown, the sending end 100 further includes a connection status module 103, which is connected to the first transceiver module 101, and is used ...

Abstract

The invention discloses a data transmission method and system based on dynamic port switching. The method comprises the following steps that: a transmitting end and a receiving end establish a connection including a first source port, and the transmitting end sets a second source port; the transmitting end transmits a message to the receiving end through the first source port; and the transmitting end establishes a connection with the second source port and transmits the message when the connection between the transmitting end and the receiving end is disabled. In the data transmission method and system, an automatic 'connection disabling' detection mechanism and a dynamic port switching mechanism are adopted, so that the problem of limitation on connections by transmission link infrastructure can be solved effectively by the dynamic port switching mechanism; automatic reconnection after disconnection on the aspect of transmission protocol is realized; and data transmission stability is ensured. The data transmission method and system are completely transparent to an application layer.

Description

technical field [0001] The invention relates to the technical field of network transmission, in particular to a data transmission method and system based on dynamic port switching. Background technique [0002] With the continuous increase of the Internet scale, the network environment has become more and more complex, and people have higher and higher requirements for the quality of data transmission. For the transmission of very large files, or the transmission of data streams such as live broadcasts, the transmission time often lasts for a long time, sometimes even for several days. In this scenario, the sending end and the receiving end establish a transmission control protocol (TCP) connection for data transmission. If the transmission link relied on is unstable, there will be transmission interruption failure during the file transfer process, and live video freezes, etc. problem, seriously affecting the user experience. [0003] Existing technologies often face the f...
