Embodiment Construction

[0070] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0071] First of all, it needs to be pointed out that whether it is a traditional Internet or a mobile network, packet loss, delay, and jitter are three important dimensions to measure the network status. They exist independently, have individuality, and at the same time show a certain correlation. Individuality means that when delay occurs, other dimensions do not necessarily occur; correlation, such as when packet loss occurs, may be accompanied by delay and jitter. Of course, in general, the correlation between jitter and delay is stronger, that is, the individual performance between the two is weak. Therefore, when designing a network quality detection method, how to reflect the independence and correlation of the three dimensions is an important basis for the accuracy of network quality assessment. Therefore, an excellent network...

Abstract

The invention provides a network quality estimation and detection method, and belongs to the application field of network technology. According to the estimation and detection method, the problem that the prior art only relies on one factor selected from package loss, time delay and jitter for network quality estimation and thus the detection result is not reliable can be solved, and three factors of package loss, time delay and jitter are combined at the same time for estimating the network quality, unreliability when one factor is used for estimation can be avoided, and the network quality can be accurately and effectively estimated. In addition, the time delay and jitter calculation method also has specific beneficial effects, and reliability of network quality estimation is greatly improved.

Description

technical field [0001] The invention relates to an evaluation and detection method and its device, in particular to a network quality evaluation and detection method and its device. Background technique [0002] In the current voip application, streaming media playback and other various streaming media application scenarios, normal estimation of network quality is particularly important for business applications. For example, in the common online video-on-demand, the method to improve customer experience is to determine the size of the code stream transmitted by the server according to the user's network situation. If the network is poor, reduce the code stream to ensure the user's basic viewing needs. When the network is good, increase the code stream. , to ensure the viewing picture and audio quality, and improve user comfort. [0003] There are three main parameters affecting network quality in mobile networks, namely packet loss, jitter and delay: [0004] Delay: refer...
