Problems solved by technology

[0003] When a large amount of data is transmitted, on the one hand, the verification process will be difficult to verify because the received data contains data of different structures, which will take a long time to verify and reduce the efficiency of data transmission; on the other hand When the amount of data is large, because the frequency of each type of data is different, the frequency of sending and receiving is inconsistent, which will make the internal data of each type of data interspersed and confused during transmission, resulting in the inability to parse and further reducing the efficiency of data transmission

Embodiment 1

[0054] refer to image 3 , a check-free method for data transmission based on TCP, comprising the following steps:

[0055] S1. Extract the original data to obtain the data to be sent, and upload the data to be sent;

[0056]Specifically, when the sender prepares to send data, the original data will be sent through the server of the sender. In this case, the original data needs to be uniformly extracted to obtain the data to be sent, which is convenient for subsequent operations.

[0057] S2. Receive the data to be sent, classify the data to be sent according to its structure and frequency to obtain the classified data and send it;

[0058] Wherein, step S2 includes the following steps:

[0059] S21. Receive the data to be sent, classify the data to be sent according to the data structure to obtain a plurality of first classification data, and upload the plurality of first classification data;

[0060] Specifically, classify all the data to be sent according to its own stru...

Embodiment 2

[0068] refer to Figure 4 , which is different from implementation 1, is further limited, the step S3 includes the following steps:

[0069] S31, receiving classified data, and matching a plurality of the second classified data with the sending service port;

[0070] Specifically, after the classification data is received, each second classification data in the classification data is matched with the corresponding service port, and the service port IP is bound with the corresponding structure and frequency, and the classification data can be directly sent with When the corresponding service port matches, it is sent, so that the corresponding port can transmit the specified data with the same structure and the same frequency in the subsequent data transmission.

[0071] S32, the classified data is sent through the corresponding sending service port after the matching is completed;

[0072] Wherein, step S32 includes the following steps:

[0073] S321. Provide a sending servi...

Embodiment 3

[0077] Different from Embodiment 2, it is further defined that the step S4 includes the following steps:

[0078] S41, providing a receiving port that matches the sending port one by one, and receiving the second classification data sent by the sending port through the receiving port;

[0079] Specifically, the IP address of the receiving port in the server of the receiving end matches the IP address of the sending port of the sending end, so each second classified data will be transmitted from a unique port, avoiding data cross confusion, and making the classified data high-quality transmitted to the receiving server.

[0080] S42, providing a one-to-one receiving service corresponding to the receiving port, and uploading the received second classification data through the receiving service;

[0081] Specifically, after the server at the receiving end receives the classified data, it is uploaded to the server at the receiving end through the service for subsequent data analy...

Abstract

The invention relates to the technical field of data transmission, in particular to a TCP (Transmission Control Protocol)-based data transmission check-free method and system, which comprises the following steps of: firstly, extracting and classifying original data to obtain classified data, uploading the classified data, then receiving the classified data, and transmitting the classified data according to a corresponding service port; and finally, receiving the corresponding data through the corresponding service port. Data needing to be transmitted are classified according to the structure and the frequency through the data transmission unit, and then the classified data are sent through the corresponding service ports, so that the data sent by the service ports are the same in structure and the same in frequency; therefore, packet sticking caused by different transmission intervals during transmission of data with different frequencies is avoided, verification does not need to be carried out when the data is received after the problem of data packet sticking is solved, transmission time and efficiency are saved, analysis failure caused by intersection of data with different structures and frequencies is avoided, and data transmission efficiency is improved. And the data transmission efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a check-free method and system for data transmission based on TCP. Background technique [0002] At present, TCP or UDP are usually used for data transmission. Since UDP data transmission is usually prone to data loss, the TCP data transmission method is generally selected. However, in actual use, when a large amount of data is transmitted through TCP Data sticky packets often occur, so the received data is usually checked before the data is received. Usually, a specified algorithm is used to calculate a check value for the original data, and the receiver uses the same algorithm. Calculate the check value once. If the check value obtained by the two calculations is the same, it means that the data is complete. After the data of the sticky packet is checked, it will be invalid and re-sent to avoid the received data being invalid and causing the parsing failure. [0003]...
