Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] The inventor found that the following phenomenon may exist in the TCP network: before the data message reaches the TCP receiver, the TCP sender determines that the data message is discarded according to the received confirmation message. Further, the TCP sender retransmits the data packet. Therefore, both the data packet and the retransmitted data packet will be transmitted in the TCP network. The above phenomena may lead to congestion in the TCP network. The inventor discovered that the reason for the above phenomenon is that the delay occurs when the data message is transmitted in the TCP network. But in fact, the data packets are not discarded.

[0078] In order to describe the present invention more clearly, before descri...

Abstract

The invention discloses a message receiving method and a device, and belongs to the field of network communication. The method comprises steps: a repeated confirmation message sent by a transmission control protocol (TCP) receiver is received, wherein the repeated confirmation message is triggered by a first data message; whether a second data message disorderly reaches the TCP receiver is detected; and if the detection result is that the second data message disorderly reaches the TCP receiver, an operation in response to the repeated confirmation message can be prevented from being executed or an operation of forwarding the repeated confirmation message to a TCP sender can be prevented from being executed. As the second data message is detected to disorderly reaches the TCP receiver, the operation in response to the repeated confirmation message can be prevented from being executed or the operation of forwarding the repeated confirmation message to a TCP sender can be prevented from being executed, the problem of repeated data message transmission due to disorder can be solved, and the purpose of greatly improving the effective network capacity can be achieved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for receiving messages. Background technique [0002] During network transmission, reliable connections are often required between different hosts to achieve reliable transmission of data packets. TCP (Transmission Control Protocol, Transmission Control Protocol) is a mechanism for reliable transmission of data packets. [0003] A TCP packet can be a data packet or an acknowledgment packet (ACK). The data message is a message including a data segment (segment) sent by a TCP sender (Transmission Control Protocol sender, TCP sender) to a TCP receiver (Transmission Control Protocol receiver, TCP receiver). The confirmation message refers to a message sent by the TCP receiver to the TCP sender according to the received data message after receiving the data message. [0004] The method for transmitting data through the TCP network provided by the prior art m...
