Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a packet loss rate calculation method, a server and a computer readable storage medium. In the invention,the packet loss rate calculation method is applied to a first agent end based on a forward error correction (FEC) protocol, and comprises the following steps: determining a maximum serial number, a minimum serial number and the number of received messages in FDP format messages received in a sampling period, wherein the message in the FDP format is sent by the second agent end and comprises a serial number field, and the serial number field comprises serial number information of the message; calculating a first packet loss rate according to the maximum serial number, the minimum serial number, the number of the messages and a preset constraint relationship among the maximum serial number, the minimum serial number, the number of the messages and the packet loss rate, wherein the first packet loss rate is the packet loss rate of the second agent end. In the embodiment of the invention, the packet loss rate can be calculated without sending the detection message, the calculation processof the packet loss rate is simplified, the detection message is prevented from occupying the bandwidth, and the flow consumption is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method for calculating a packet loss rate, a server, and a computer-readable storage medium. Background technique [0002] At present, in the process of using virtual private network (Virtual Private Network, VPN) technology to build a secure private network, due to certain packet loss and jitter in the mobile network or wifi network, when the terminal accesses the secure network through the VPN, it often freezes. , especially for terminals with high-speed data transmission requirements, such as intelligent robots in the cloud, the existing dedicated network experience is very poor. FEC (Forward Error Correction) technology is a method of using data to transmit redundant information. When an error occurs during transmission, it will allow the receiver to rebuild the data, thereby increasing the reliability of data communication. In order to...
