Embodiment Construction

[0093] Embodiments of the present invention provide a link quality assessment method and a device thereof, which are used to assess link quality and further improve the accuracy of link quality assessment. In the embodiment of the present invention, the quality of the link to be evaluated is evaluated according to the bandwidth utilization rate and the similarity set of the sampling sequences of M cycles, that is, the quality of the link is evaluated through two dimensions, thereby increasing the dimension of evaluating the quality of the link , which improves the comprehensiveness and accuracy of link quality assessment.

[0094] The embodiments of the present invention are applicable to fixed bandwidth access networks of networks such as PON, xDSL, and EoC. In the embodiment of the present invention, the PON network is taken as an example for introduction. For example, figure 1 shown, figure 1 It is a schematic diagram of a system architecture of a network to which the emb...

Abstract

The invention relates to the network test field, especially a link quality assessment method and device used for assessing link quality, and further improving link quality assessment comprehensiveness and accuracy. The method comprises: obtaining the sampling data of a link to be assessed in M periods; determining a bandwidth availability ratio and a similarity set of sampling sequences of M periods according to the sampling data; and performing quality assessment on the link to be assessed at least based on the bandwidth availability ratio and the similarity set of sampling sequences of the M periods. The similarity set of sampling sequences of the M periods can reflect the similarity among sampling data of the M periods; further, quality assessment is performed on the link to be assessed according to the bandwidth availability ratio and the similarity set of sampling sequences of the M periods, thereby increasing the dimensions of assessing link quality, and improving link quality assessment comprehensiveness and accuracy.

Description

technical field [0001] The invention relates to the field of network testing, in particular to a link quality evaluation method and device. Background technique [0002] With the large-scale development of urban optical networks, operators are deploying fixed broadband access networks in full swing, such as Passive Optical Network (PON) networks, Digital Subscriber Line (xDSL), A fixed broadband access network in an Ethernet over cable (Ethernet Over Cable, EoC for short) network. Taking the PON network as an example, the main part of the fixed broadband access network structure includes the wired broadband access network and the Layer 2 or Layer 3 network elements of the data metropolitan area network connected to the wired broadband access network. [0003] Due to the differences in the size of the coverage area of ​​the PON network, the number of access users, user types, access rates, and user network usage behaviors, the bandwidth usage of the uplink from a single PON ...
