Fig. 2 is a flowchart of a method for processing communication data according to one embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S20, monitoring data packets received by a receiving end in a communication process, and sequentially writing the received data packets into a data packet sequence, wherein a plurality of data packets contained in the data packet sequence are ordered according to receiving time stamps;
specifically, a data packet received by a receiving end in a communication process is monitored; when receiving a data packet, the receiving end equipment records the related information of the data packet, including the content of the data packet and a receiving time stamp; sequentially writing the received data packets into a sequence of data packets, wherein an array, list, or other data structure may be used to store the sequence of data packets; when writing the data packet sequence, the data packets are ordered according to the receiving time stamp so as to ensure that a plurality of data packets in the data packet sequence are arranged according to the receiving time sequence.
Step S22, the receiving end sequentially performs data verification on the data packets in the data packet sequence;
specifically, when the receiving end receives the first data packet in the data packet sequence, the data packet is checked by using a pre-agreed data check algorithm, for example, cyclic redundancy check (Cyclic Redundancy Check, CRC) or hash check. If the checking result shows that the data packet has no error, the receiving end continues to receive the next data packet.
Step S24, if the checking result of any one of the data packets to be checked in the data packet sequence is damaged, stopping feeding back the communication confirmation information corresponding to the data packet to be checked to the transmitting end, wherein the transmitting end does not receive the communication confirmation information corresponding to the data packet to be checked in a preset time, and resending the data packet to be checked.
In the step S24, the communication acknowledgement information refers to a communication completion flag code (UNIX NET ACK, UNA), and the receiving end sends acknowledgement information to the sending end after successfully receiving and verifying the data packet, so as to inform the sending end that the data packet has been successfully received.
Specifically, in the communication with the bottom layer in the data application, when the sending end sends a data packet to the receiving end, the receiving end firstly checks the data packet, if the check result indicates that the check result of any one data packet to be checked in the data packet sequence is damaged, the receiving end stops feeding back communication confirmation information corresponding to the data packet to be checked to the sending end, wherein if the receiving end checks that the last data packet in the data packet sequence is damaged, the receiving end sends a message of communication completion to the sending end.
Based on the above steps S20 to S24, a manner of monitoring the data packets received by the receiving end in the communication process and sequentially writing the received data packets into the data packet sequence and sequentially performing data verification on the data packets in the data packet sequence by the receiving end is adopted, if the verification result of any one of the data packets to be verified in the data packet sequence is damaged, the feedback of the communication confirmation information corresponding to the data packets to be verified to the sending end is stopped, so that the purpose of low resource occupancy rate under the same communication data volume is achieved, the technical effects of reducing the resource occupancy rate and improving the communication efficiency under the same communication data volume are achieved, and the technical problems of high resource occupancy rate and low communication efficiency under the same communication data volume in the related art are solved.
Optionally, the processing method of the communication data further includes:
in step S251, when the total length of the data packet received by the receiving end exceeds the threshold value, the receiving end starts to perform data verification on the data packet sequence.
Specifically, the receiving end firstly sets a threshold value for determining the data packet sequence to start the data verification operation when the total length of the received data packets exceeds the total length. The threshold may be determined based on the particular application scenario and the size of the data packet. Then, when the total length of the data packet received by the receiving end exceeds a set threshold, the receiving end will start to perform data check on the data packet sequence, and the data check can adopt various different check algorithms, such as CRC check, parity check, and the like. In the process, the receiving end organizes the received data packet sequence according to a certain rule, and performs verification calculation on the whole data packet sequence. The verification calculation process can be determined according to a specific verification algorithm, and is generally to calculate each byte in the data packet, and compare the calculation result with a pre-calculated verification value of the receiving end. Finally, if the data verification is passed, the receiving end marks the received data packet sequence as reliable data, sends a verification completion Acknowledgement (ACK) to the sending end, and transmits the data packet to an upper layer application for processing; and if the data verification is not passed, requesting the transmitting end to retransmit the data.
Based on the step S251, when the total length of the data packet received by the receiving end exceeds the threshold, the receiving end starts to perform data verification on the data packet sequence, so as to ensure the integrity and accuracy of the received data packet, thereby improving the reliability and safety of data transmission.
Optionally, the processing method of the communication data further includes:
in step S252, the receiving end sequentially performs data verification on the data packets in the data packet sequence by taking one data packet as a unit, and when any one data packet to be verified is verified to be damaged, deletes at least one data packet located behind the data packet to be verified in the data packet sequence, and feeds back the data packet to be verified to the transmitting end.
Specifically, after receiving a data packet, the receiving end performs data verification operation on the data packet, and if the data packet passes the verification, the receiving end receives the next data packet to be verified, and the operation is repeated. When the receiving end checks any data packet to be checked, the receiving end finds that the data packet to be checked is a damaged data packet, and then deletes at least one data packet positioned behind the damaged data packet in the data packet sequence, so that the receiving end is ensured not to use the damaged data packet for subsequent processing. And the receiving end feeds back the damaged data packet to the sending end, and the sending end can retransmit the data packet or take other measures to ensure the reliable transmission of the data after receiving the feedback. Repeating the above operation until the receiving end completes the verification of the whole data packet sequence.
Based on the step S252, the receiving end sequentially performs data verification on the data packets in the data packet sequence by taking one data packet as a unit, and deletes at least one data packet positioned behind the data packet to be verified in the data packet sequence when any one data packet to be verified is verified to be damaged, and feeds back the data packet to be verified to the transmitting end, so that the accuracy and the integrity of communication data are ensured, errors and losses in the transmission process of the communication data can be effectively prevented, and the reliability and the stability of the transmission of the communication data are improved.
Optionally, the receiving end generates communication confirmation information corresponding to the data packet to be verified under the condition that the verification result of the data packet to be verified is successful, and feeds back the generated communication confirmation information to the sending end.
Specifically, after receiving the data packet to be checked, the receiving end checks the data packet first and compares the data packet with the checksum in the data packet so as to ensure the integrity and accuracy of the data packet. For example, a hash function is used to calculate the digest of the data packet. If the verification result is successful, the receiving end generates communication confirmation information corresponding to the data packet to be verified. The communication acknowledgement information UNA code is used for indicating the contents such as acknowledgement of the received data packet, state information of the receiving end, processing result of the data packet and the like. After the communication confirmation information is generated, the receiving end feeds back the communication confirmation information to the transmitting end. Reliable transmission of communication data can be achieved based on the above operations.
Optionally, each time the transmitting end receives a predetermined number of data packets, it monitors whether communication acknowledgement information matching the predetermined number of data packets is received, and if there is at least one communication acknowledgement information corresponding to the data packets that is not received, the data packets are retransmitted until the communication acknowledgement information of the data packets is received.
Specifically, the transmitting end will first send a certain number of data packets to the receiving end. Once the predetermined number of data packets has been transmitted, the transmitting end starts to monitor whether communication acknowledgement information matching the number of data packets transmitted is received. If the communication acknowledgement information matches the number of the transmitted data packets, the transmitting end can continue to transmit the next data packet. If at least one communication acknowledgement message corresponding to the data packet is not received, the transmitting end retransmits the data packet. This process continues until a communication acknowledgement is received for the packet, ensuring reliable transmission of the packet.
The steps can ensure reliable transmission of communication data even if packet loss or errors occur in the communication process. By monitoring and retransmitting the data packets, the transmitting end can ensure that the receiving end successfully receives all the data.
Optionally, the processing method of the communication data further includes:
step S261, the transmitting end encodes the data to be transmitted to generate a data packet;
step S262, the transmitting end judges whether the length of the data packet exceeds a threshold value;
step S263, if the length of the data packet exceeds the threshold value, the transmitting end segments the data packet, divides the data packet into a plurality of fragments, assembles the head address and the length of the fragments into a header, assembles the data part into an effective data area, and encapsulates the header and the effective data area;
in step S264, the transmitting end starts to transmit the encapsulation result of the data packet to the receiving end.
Specifically, firstly, a transmitting end processes data to be transmitted, codes the data to be transmitted, and generates a data packet so as to be correctly analyzed and reconstructed in the transmission process. Then, the transmitting end judges whether the length of the data packet exceeds a preset threshold value. If the length of the data packet exceeds the threshold, the sender performs segmentation on the data packet, i.e. the sender divides the data packet into a plurality of fragments, assembles the head address and the length of each fragment into a header, assembles the data part into a valid data area, and encapsulates the header and the valid data area. Finally, the transmitting end starts to transmit the encapsulation result of the data packet to the receiving end so that the receiving end can analyze and process the data.
Based on the steps S261 to S264, the transmitting end encodes the data to be transmitted to generate a data packet; the transmitting end judges whether the length of the data packet exceeds a threshold value; if the length of the data packet exceeds the threshold value, the transmitting end performs segmentation on the data packet, divides the data packet into a plurality of fragments, assembles the head address and the length of the fragments into a head, assembles the data part into an effective data area, and encapsulates the head and the effective data area; the sending end starts to send the encapsulation result of the data packet to the receiving end, so that the purpose of low resource occupancy rate under the same communication data volume is achieved, the technical effects of reducing the resource occupancy rate and improving the communication efficiency under the same communication data volume are achieved, and the technical problems of high resource occupancy rate and low communication efficiency under the same communication data volume in the related art are solved.
Fig. 3 is a schematic diagram of a method for processing communication data according to an embodiment of the present invention, as shown in fig. 3, the method for processing communication data includes the following steps:
first, when a receiving end receives a plurality of data packets, for example, 123, 456, 789 and other data packets, the received data packets are sequentially written into a data packet sequence, and data verification is sequentially performed on the data packets in the data packet sequence, wherein when the total length of the received data packets exceeds a threshold value, the receiving end starts to perform data verification on the data packet sequence. And secondly, the receiving end transmits communication confirmation information UNA, and when the receiving end receives the UNA, the receiving end continuously transmits subsequent data. When the data is damaged, the transmitting end retransmits the damaged data packet when the interval is larger than the preset number N of data packets. For example, when packet 1 is corrupted but packet 4 has been transmitted, packet 1 is retransmitted. Then, after the subsequent transmission of each N packets is finished, the transmitting end retransmits the data packet after not receiving the UNA code of the retransmitted data packet until receiving the UNA code of the data packet, and after the N data packets, the transmitting end completes retransmission after receiving the ACK code, thereby avoiding serious influence on the network when three continuous retransmissions continuously fail when using a transmission control protocol (Transmission Control Protocol, TCP). Finally, the data packet is transferred to IP Framing and Transport Management layer application for processing.
