Embodiment Construction
[0066] The inventor has found through research that when data communication is performed between two communication devices, the communication data will be transmitted from one communication device to another communication device, and during the transmission process, the communication data sent by one of the communication devices may not be able to Received in its entirety by another communication device. For example, when the communication network where the two communication devices are located is unstable, some data packets may be lost during the data transmission process of the communication data sent by one of the communication devices, resulting in the loss of data packets received by the other communication device. The part of the lost data packets is missing in the communication data, so that the communication device does not receive the complete communication data. However, for a communication device receiving communication data, it is impossible to know whether the rec...

The present invention discloses a communication data processing method and device. The method comprises the steps of: receiving data to be processed, wherein the data to be processed comprises a plurality of data blocks, the standard Hash value of each data block and the number N of the data blocks, the standard Hash values of the data blocks are the Hash values corresponding to the complete datablocks, the number N of the data block is the number of the data blocks in the complete communication data blocks, and N is a positive integer being larger than 1; and according to the data features of the data blocks, calculating the actual Hash value of each data block, comparing the actual Hash value with the standard Hash value, and if the number of the data blocks which have the actual Hash values being equal to the standard Hash values, determining that the plurality of data blocks included in the data to be processed are complete communication data. Through comparison of the actual Hashvalue of each data block in the received data to be processed and the standard Hash value, it is determined whether the communication data received by a receiving terminal is completed or not.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for processing communication data. Background technique [0002] With the continuous development of data communication technology, various communication devices usually interact with a large amount of communication data. During the transmission of communication data from one communication device to another, the data received by the receiving end may not be the complete data sent by the sending end due to reasons such as partial data packet loss. The receiving end of the communication data is mainly responsible for receiving the communication data, and cannot know whether the received communication data is complete. Therefore, how to ensure that the data received by the receiving end is all the data sent by the sending end is an important problem to be solved when two communication devices perform data interaction.
