Description
Technical Field
The invention belongs to the technical field of dummy resource monitoring and management, and particularly relates to a method and a system for analyzing and managing a line of a passive optical splitter of an optical network.
Background
Under the background that each major operator vigorously pushes light to enter and exit copper, at present, broadband networks of each major operator are basically established on the basis of Optical fiber networks, and Passive Optical Networks (PONs) are often adopted. The PON architecture generally includes an Optical Line Termination (OLT), an Optical Distribution Network (ODN), and an Optical Network Unit (ONU). Take PON including ONUs as an example. The ODN refers to a portion between the OLT and the ONU, and is used for the OLT to communicate with the ONU. The ODN includes supporting devices such as pipes, optical fibers, a primary optical splitter (also referred to as a primary optical splitter), a secondary optical splitter (also referred to as a secondary optical splitter), and an optical cross-connect box, which are all passive devices of the optical network and are generally also referred to as dummy resources. The passive nature of the dumb resources prevents electronic automation from being employed to manage the dumb resources.
Due to the characteristics of the optical network passive equipment, after the optical network passive equipment has problems, the state of the optical network passive equipment cannot be reported automatically and acquired, equipment or optical fiber faults cannot be found in time, and the optical network passive equipment is exposed through user complaints or large-area faults, so that poor use perception of users is caused. In order to solve the problem that the optical network passive device cannot automatically report and acquire the performance state of the optical network passive device through collection, operators try to add probes to the optical network passive device, install active probes on a primary optical splitter and a secondary optical splitter which have optical fiber splitting and are prone to generating problems, and feed back the optical power intensity passing through the probes in real time, so that the optical network passive device is monitored. But such active probes are ultimately limited to use in some special scenarios and small fiber optic network coverage. The following problems are caused by mounting the probes on the first-stage optical splitter and the second-stage optical splitter: 1. a power supply for supplying power to the probe is required to be added at the position where the probe is installed; 2. a large amount of passive equipment exists in the passive optical network with large area coverage, and the cost for purchasing probes is high; 3. the probe equipment is connected in series, so that the installation and maintenance workload of the assembly and maintenance personnel is increased; 4. the probe is easy to age in the field environment, and the probe itself is damaged by the quality of the circuit. Based on the limitations of the probe scheme, the industry continuously seeks an effective automatic monitoring and management scheme for passive devices of the optical network, so as to be applicable to the passive optical network with large-area coverage at present.

The embodiment is suitable for the quality analysis management of the passive optical splitter applied to the optical network with one-level optical splitting.
The method for analyzing and managing the line of the passive optical splitter of the optical network mainly comprises the following steps:
line quality index acquisition and storage steps:
the method comprises the steps of obtaining a plurality of line quality indexes of a line where ONU equipment is located at different moments, and storing equipment information of the ONU equipment and each line quality index into a distributed storage database cluster according to preset rules. The line refers to a transmission line between the ONU device and the OLT device to which the ONU device is connected. The line quality index of the line where the ONU equipment is located is preferably a line optical attenuation value. The line optical attenuation value is a difference value between optical power transmitted by a PON port of the OLT equipment and optical power received by an uplink port of the ONU equipment.
The method specifically comprises the following steps: and the product platform issues tasks to the acquisition gateway, and the acquisition gateway performs dynamic load according to the service and then issues the dynamic load to the preposed acquisition service. The pre-acquisition service acquires the line quality index data, then pushes the equipment information of the ONU equipment and the acquired line quality index data corresponding to the ONU equipment to the storage service, and then pushes the equipment information of the ONU equipment and the acquired line quality index data corresponding to the ONU equipment to the distributed storage database cluster by the storage service.

For example, the identity numbers of the ONU devices in the same local area are divided into one database, and correspondingly, the identity numbers in another local area are divided into another database, or the network access time of the ONU devices corresponding to the identity numbers in the same time period is divided into one database, and the network access time of the ONU devices corresponding to the identity numbers in another time period is divided into another database.

Finally, the ONU equipment generates a plurality of marks, the number of the marks is the same as the number of the line light attenuation values, and the marks are sequenced according to the time sequence of line light attenuation value acquisition.
And when the number of times of the substandard state in the mark of the ONU equipment for the first preset number of times is larger than a first threshold value, judging that the ONU equipment is the substandard ONU equipment, extracting the equipment information of the ONU equipment and writing the equipment information into the high-performance database cluster.

The method and the device perform judgment based on a plurality of continuous samples of the ONU equipment, and avoid misjudgment caused by judging that the ONU equipment does not reach the standard due to accidental faults.
The method comprises the following specific steps: the data extraction service receives tasks of the product platform, periodically analyzes whether the line optical attenuation value of the line where the ONU equipment is located, which is acquired in a period, reaches the standard or not, and then marks the ONU equipment, wherein the marking is divided into a standard state or a non-standard state. And the data extraction service determines the unqualified ONU equipment according to the marking state of the ONU equipment for a first preset number of times, and then pushes the equipment information of the unqualified ONU equipment to the high-performance database cluster by the distributed storage database cluster according to the data writing service.

The resource organization relationship of the non-compliant ONU device comprises non-compliant ONU device information and a link topology of the non-compliant ONU device. Preferably, the image of the resource organization of the optical network is generated periodically, for example, 7 days, 10 days or 30 days, according to the new installation or removal of the ONU device, and thus the image of the resource organization of the optical network is a relatively dynamic image. The resource organization portrait of the unqualified ONU equipment is a dynamic portrait, and when the high-performance database cluster is updated, the resource organization portrait of the unqualified ONU equipment needs to be redrawn again.

The ratio of the total number of first splitters to which the second splitter is connected to the maximum number of first splitters to which the second splitter can be connected can be expressed as: the total number (ONU 3) of the first optical splitters connected to the second optical splitter/the maximum number (ONUmax 2) of the first optical splitters connectable to the second optical splitter, and the fourth threshold is a fourth configurable proportion, which can be optimally configured according to specific requirements. The ratio of the number of the first optical splitters, which are connected to the second optical splitter and are predicted to have a fault, to the total number of the first optical splitters, which are connected to the second optical splitter, may be expressed as: the first optical splitter number (ONU 4) for prejudging that a fault occurs and the second optical splitter are connected to each other/the first optical splitter total number (ONU 3) for connecting the second optical splitter, and the fifth threshold is a fifth configurable proportion, and the fifth threshold may be optimally configured according to specific requirements.
