Data processing system and method

Abstract

The invention provides a data processing system and method, and the method comprises the steps: segmenting data to be processed through a segmentation module, and transmitting a plurality of obtained segmented data units to a receiving detection module through a data transmission module; and the receiving detection module splices the plurality of segmented data units, and if it is judged that the lost segmented data units exist according to a data splicing result, a corresponding sending request is generated, so that the lost segmented data units are inquired and obtained from the storage module, and the data splicing result is updated. According to the system, the to-be-processed data is segmented through the segmentation module, so that the data flow transmitted each time is small, the continuity of data transmission is ensured, and the packet loss resistance is improved; the data splicing result is detected through the receiving detection module, the lost segmented data unit can be found in time, the lost segmented data unit can be quickly inquired from the storage module and transmitted, and due to the fact that only the lost segmented data unit needs to be transmitted again, the delay time is shortened.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing system and method. Background technique [0002] The wireless channel is a metaphor for the path between the sending end and the receiving end in wireless communication. Data can be transmitted through the wireless channel; for radio waves, there is no tangible connection between the sending end and the receiving end, and the propagation path There may be more than one. In order to vividly describe the work between the sending end and the receiving end, it can be considered that there is an invisible road connecting the two. This connecting path can be called a wireless channel, and the wireless channel is often called The wireless "frequency band (Channel)". Since wireless channels usually have problems such as high bit error rate, large bandwidth fluctuations, and limited channel bandwidth, there may be packet loss problems during data transmi...

AI Technical Summary

Problems solved by technology

Since wireless channels usually have problems such as high bit error rate, large bandwidth fluctuations, and limited channel bandwidth, there may be packet loss problems during data transmission. In the end, you can only choose to retransmit the entire segment of data. This method has anti-packet loss performance. Poor, long delay time
