However, the RTT fluctuates with the state of the network, that is, when the network is good, the RTT is small, and when the network is poor, the RTT is large, and the RTT cannot be accurately determined, and the RTO cannot be accurately determined, and the accuracy of the RTO is relatively low. Low

Abstract

The invention discloses a retransmission expiration time optimization method, retransmission expiration time optimization equipment, and a computer readable storage medium. The method comprises the steps of when TCP data to be transmitted is monitored, determining whether the quantity of transmitted TCP data reaches a preset value, wherein every transmission of TCP data is completed, the round trip delay and the retransmission expiration time of the transmitted TCP data are used as a sample set to be written into a preset sample database; if the quantity of the transmitted TCP data does not reach a preset value, determining the retransmission expiration time of the TCP data to be transmitted according to the bit value of the TCP data to be transmitted; and if the quantity of the transmitted TCP data reaches or exceeds the preset value, determining the retransmission expiration time of the TCP data to be transmitted according to a preset sample regression model and each sample set in the sample database. According to the method, equipment and medium provided by the invention, accuracy of the retransmission expiration time can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a retransmission timeout optimization method, device and computer-readable storage medium. Background technique [0002] TCP (Transmission Control Protocol, Transmission Control Protocol) provides a connection-oriented and reliable byte stream to the application layer through mechanisms such as data segmentation, sending number, receiving confirmation, timeout retransmission, out-of-order reassembly, discarding duplicate packets, and flow control. service, and use confirmation and timeout retransmission mechanisms to ensure reliable data transmission. [0003] In order to avoid the loss of TCP segments when transmitting TCP data, RTO (Retransmission Timeout, retransmission timeout) is basically equal to RTT (Round Trip Time, round-trip delay). However, the RTT fluctuates with the state of the network, that is, when the network is good, the RTT is small, and when th...
