Abstract

The embodiment of the invention discloses a network delay jitter measurement method and device, computer equipment and a storage medium. The method comprises the following steps: continuously obtaining a preset number n of data packets from a network link; sequentially calculating a delay jitter change value D<n-1> between every two adjacent data packets according to the sending time Sn and the receiving time Rn of each data packet and a preset first formula, and forming a D value sequence; performing iterative calculation on the D value sequence according to a preset iterative algorithm modelto obtain a delay jitter evaluation value J<n-1>, forming a first J value sequence; determining the number of the delay jitter evaluation value J<n-1> exceeding preset value range in first J value sequence and calculating the percentage of the determined number; and if the percentage is greater than the preset proportion, generating corresponding network delay jitter early warning information toprompt a user to carry out corresponding network optimization. According to the method and the device, the network delay jitter condition in the network link can be more accurately measured.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method, device, computer equipment and storage medium for measuring network delay and jitter. Background technique [0002] Network delay jitter refers to the change in the transmission delay of messages in the network when a host sends a message to another host on a fixed network link. Ideally, if the delay of network transmission remains unchanged, there will be no jitter in the network. However, in the actual application process, data packet transmission is easily affected by factors such as link congestion and network equipment sending and receiving queues, which will inevitably lead to network delays. presence of jitter. Network delay jitter is an important indicator to measure network quality. [0003] At present, the algorithms for delay jitter mainly include MPPDV, MAPDV, MAPDV2, RTP / RTCP, etc., all of which rely on the average value of the change in delay for calcula...

AI Technical Summary

Problems solved by technology

The large dependence on the average value tends to reduce or amplify the peak of data transmission delay, and the short-term high state has an impact on the delay jitter value

Furthermore, the optimization scheme and effect evaluation of network delay and jitter needs to be based on the premise of being able to accurately measure delay and jitter, and the traditional network delay and jitter algorithm has certain limitations.
