Problems solved by technology

These shortcomings lead to problems such as low parsing efficiency, high network bandwidth occupation, and high CPU resource usage during message communication.
[0004] In addition, due to the use of XML and JSON to transmit data, the communication protocol versions of the two parties must be consistent, otherwise the data cannot be transmitted normally
[0005] To sum up, in the prior art, data cannot be transmitted when the versions of the communication protocols of the two parties are inconsistent, and when data is transmitted when the versions of the communication protocols of the two parties are consistent, the network bandwidth is high and the CPU resource usage is high.

Embodiment 3

[0228] The technical effect of the device for providing data transmission in Embodiment 3 is the same as that of the corresponding method embodiment in Embodiment 1, and details are not repeated here.

[0229] Figure 7 It is a schematic structural diagram of a device for transmitting data in the fourth embodiment of the present invention. Embodiment 4 is a device corresponding to Embodiment 2, specifically including:

[0230] A protocol auto-negotiation manager 701, configured to be backward compatible with the communication protocol version through handshaking;

[0231] The command encoder / decoder 702 is used to receive the encoding result, and decode the encoding result to obtain the message command according to the order of the field type according to the communication protocol version.

[0232] Specifically, the protocol auto-negotiation manager 701 is also configured to learn that the communication protocol version is different through the handshake, and adop...

Embodiment 4

[0238] The technical effect of the device for transmitting data provided in Embodiment 4 is the same as that of the corresponding method embodiment in Embodiment 2, and details are not repeated here.

[0239] see Figure 8 It is a schematic diagram of the data exchange between the sending end and the receiving end, which specifically includes the following steps:

[0240] When performing data interaction, the automatic negotiation of the communication protocol between the two parties is first carried out:

[0241] Step 1: When the message sending end initiates a connection request message to the message receiving end, the protocol auto-negotiation manager 601 sends the protocol negotiation command to the command encoder / decoder 602, and the command encoder / decoder 602 encodes the protocol negotiation command into bytes array and write to the network.

[0242] Step 2: When the message receiving end reads the byte array from the network, the command encoder / decoder ...

Abstract

The invention provides a data transmission method. The method comprises the following steps: carrying out backward compatibility on a communication protocol version through handshaking; coding a message command according to the communication protocol version and a sequence of a field type, so as to obtain a coding result; and sending the coding result. The embodiment of the invention further discloses a data transmission device; data transmission can be realized under the condition that the communication protocol versions of both parties are inconsistent; and meanwhile, the occupied network bandwidth and the CPU (Central Processing Unit) resource utilization rate are effectively reduced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for transmitting data. Background technique [0002] Existing technical solutions for data transmission mainly use general data exchange formats such as Extensible Markup Language (XML) and Object Notation (JSON) as communication protocols to complete cross-platform message communication and data exchange. Furthermore, some auxiliary functions will be provided, such as the function of generating communication protocol interfaces based on metadata description files. [0003] Text protocols such as XML and JSON have the disadvantages of redundant data and complex analysis. The reason is that when they transmit data, in addition to valid data, they also need to transmit a series of redundant data such as XML or JSON tags. When parsing, it is also necessary to perform tag matching before extracting valid data. These shortcomings lead to problems such as low parsing effi...
