Abstract

A method and system for data transmission, and a non-transitory storage medium. The method for data transmission is applied to a receiving terminal. The receiving terminal includes a Transmission Control Protocol (TCP) data transmission module. The method includes: monitoring a TCP packet currently stored in the TCP data transmission module, the TCP packet includes a TCP acknowledgment (ACK) packet and a TCP data packet; determining whether the TCP ACK packet and the TCP data packet coexist in the stored TCP packets; and in response to the determination that the TCP ACK packet and the TCP data packet coexist in the TCP packet, processing the TCP ACK packet. In the present disclosure, a type of the packet currently stored in the receiving terminal is determined. If the TCP ACK packet and the TCP data packet coexist, the TCP ACK packet is processed.

First claim

What is claimed is:

1. A method for data transmission, applied to a receiving terminal comprising a transmission control protocol (TCP) data transmission module, wherein the method comprises:
monitoring a TCP packet currently stored in the TCP data transmission module, wherein the TCP packet comprises at least one of a TCP acknowledgment (ACK) packet or a TCP data packet, and the TCP data packet comprises another type of TCP packet other than the TCP ACK packet;
determining whether the TCP ACK packet and the TCP data packet coexist in the TCP packet;
in response to the determination that the TCP ACK packet and the TCP data packet coexist in the TCP packet, processing the TCP ACK packet;
in response to the determination that the TCP ACK packet and the TCP data packet do not coexist, determining whether only the TCP data packet exists in the TCP packet;
in response to the determination that only the TCP data packet exists in the TCP packet, determining whether an amount of data currently processed and to be transmitted by the receiving terminal reaches a data amount threshold in a current network environment;
in response to the determination that the amount of data does not reach the data amount threshold, processing the TCP data packet;
in response to the determination that the amount of data reaches the data amount threshold, processing a minimal portion of the TCP data packet to prevent prioritized transmission of subsequent TCP ACK packets from being blocked due to an accumulation of TCP data after most recent transmission, without wasting resources for a next transmission, and determining whether the receiving terminal has enough data for the next transmission to avoid wasting grant or assignment; and
in response to the determination that the receiving terminal has adequate data for the next transmission, determining whether the TCP ACK packet and the TCP data packet coexist in the TCP packet.

2. The method for data transmission according to claim 1 , wherein the TCP data transmission module comprises a first data storage queue and a second data storage queue, the first data storage queue is configured to store the TCP ACK packet, and the second data storage queue is configured to store the TCP data packet, and
the method further comprises:
in response to receiving the TCP packet transmitted by a transmitting terminal, storing the TCP ACK packet in the TCP packet in the first data storage queue, and storing the TCP data packet in the TCP packet in the second data storage queue.

3. The method for data transmission according to claim 1 , wherein prior to determining whether the amount of data currently processed and to be transmitted by the receiving terminal reaches the data amount threshold in the current network environment, the method further comprises: calculating the data amount threshold based on a maximum transmitting capability configured by the current network environment for the receiving terminal and a previous actual transmitting condition of the receiving terminal within a preset time interval.

4. The method for data transmission according to claim 1 , wherein processing the TCP ACK packet comprises:
numbering the TCP ACK packet to determine a transmission priority of the TCP ACK packet.

5. The method for data transmission according to claim 4 , subsequent to numbering the TCP ACK packet, further comprising:
encrypting the numbered TCP ACK packet.

6. A system for data transmission, applied to a receiving terminal, the system comprising:
at least one processor; and
a memory configured to store instructions executable by the at least one processor; wherein the at least one processor is configured to execute the instructions to:
monitor a transmission control protocol (TCP) packet currently stored in a TCP data transmission module of the receiving terminal, wherein the TCP packet comprises at least one of a TCP acknowledgment (ACK) packet or a TCP data packet;
determine whether the TCP ACK packet and the TCP data packet coexist in the TCP packet;
in response to the determination that the TCP ACK packet and the TCP data packet coexist, process the TCP ACK packet in response to the determination that the TCP ACK packet and the TCP data packet do not coexist, determine whether only the TCP data packet exists in the TCP packet;
in response to the determination that only the TCP data packet exists in the TCP packet, determine whether an amount of data currently processed and to be transmitted by the receiving terminal reaches a data amount threshold in a current network environment;
in response to the determination that the amount of data does not reach the data amount threshold, process the TCP data packet;
in response to the determination that the amount of data reaches the data amount threshold, process a minimal portion of the TCP data packet to prevent prioritized transmission of subsequent TCP ACK packets from being blocked due to an accumulation of TCP data after most recent transmission, without wasting resources for a next transmission, and determine whether the receiving terminal has enough data for the next transmission to avoid wasting grant or assignment; and
in response to the determination that the receiving terminal has adequate data for the next transmission, determine whether the TCP ACK packet and the TCP data packet coexist in the TCP packet.

7. The system for data transmission according to claim 6 , wherein the at least one processor is further configured to implement a first data storage queue and a second data storage queue, the first data storage queue is configured to store the TCP ACK packet, and the second data storage queue is configured to store the TCP data packet; and
the at least one processor is further configured to: in response to receiving the TCP packet transmitted by a transmitting terminal, store the TCP ACK packet in the TCP packet in the first data storage queue and store the TCP data packet in the TCP packet in the second data storage queue.

8. The system for data transmission according to claim 6 , wherein the at least one processor is further configured to calculate the data amount threshold based on a maximum transmitting capability configured by the current network environment for the receiving terminal and a previous actual transmitting condition of the receiving terminal within a preset time interval.

9. The system for data transmission according to claim 6 , wherein the at least one processor is further configured to number the TCP ACK packet to determine a transmission priority of the TCP ACK packet.

10. The system for data transmission according to claim 9 , wherein the at least one processor is further configured to: subsequent to numbering of the TCP ACK packet, encrypt the numbered TCP ACK packet.

11. A non-transitory storage medium storing computer program instructions thereon, the computer program instructions, when executed by a processor, cause the processor to:
monitor a transmission control protocol (TCP) packet currently stored in a TCP data transmission module of a receiver terminal, wherein the TCP packet comprises at least one of a TCP acknowledgment (ACK) packet or a TCP data packet, and the TCP data packet comprises another type of TCP packet other than the TCP ACK packet;

in response to the determination that the TCP ACK packet and the TCP data packet coexist in the TCP packet, process the TCP ACK packet;
in response to the determination that the TCP ACK packet and the TCP data packet do not coexist, determining whether only the TCP data packet exists in the TCP packet;
in response to the determination that only t
