Fig. 1 shows a schematic diagram of the related art.

As shown in fig. 1, in the related art, an OLT slice 1 has traffic 1 and traffic 2, where the traffic 1 corresponds to a PON port 1 and a PON port 2, and the traffic 2 corresponds to the PON port 1. The OLT slice 2 has traffic 1 and traffic 2 below it. The OLT slice 1 and the OLT slice 2 belong to the same OLT. And the mapping relation among the OLT slice, the service and the PON port is that the slice is mapped to the service and then mapped to the PON port.

Under the condition that the PON port 1 is divided into the OLT slice 2, the mapping relation between the PON port 1 and the service 1 and the mapping relation between the PON port 1 and the service 2 are deleted, then the PON port 1 is divided into the OLT slice 2, and then the mapping relation between the PON port 1 and the service 1 and the mapping relation between the PON port 1 and the service 2 are reestablished.

After the configuration is completed, the OLT slice 1 has a service 1 and a service 2, where the service 1 corresponds to the PON port 2. There are traffic 1 and traffic 2 under OLT slice 2. Traffic 1 corresponds to PON port 1 and traffic 2 also corresponds to PON port 1.

In the related technology, after slicing is divided, physical resources of the OLT are unchanged, logical resources are changed, the OLT stores PON resources in each service template, the PON in the service template needs to be deleted first when the slicing is allocated, at this time, a service is interrupted, after main OLT physical resources are divided into one virtual OLT slice by the OLT controller, an OLT slice service identical to the original service needs to be reconfigured by the controller, the original service in a PON port is not protected, in the configuration process, the interruption time of the original service is long, the influence on the service is large, and user experience is poor.

The present disclosure provides a configuration method, which reduces service interruption time and improves user experience.

Fig. 2 illustrates a flow diagram of an OLT slice-based configuration method according to some embodiments of the present disclosure.

As shown in fig. 2, the configuration method based on the OLT slice includes steps S110 to S130. In some embodiments, the configuration method is performed by the OLT to which the target OLT slice belongs.

In step S110, a configuration instruction is received. The configuration instruction comprises a passive optical network PON port to be processed and a target optical line terminal OLT slice.

In some embodiments, the configuration instructions are generated by a controller corresponding to the OLT to which the target OLT slice belongs. For example, the controller is used to control a plurality of OLTs. The configuration efficiency and the user experience are further improved by the mode of generating and issuing the configuration command by the controller.

In step S120, a mapping relationship between the PON port to be processed and the service to be processed corresponding to the PON port to be processed is queried. The mapping relationship is from the PON port to be processed to the traffic to be processed. For example, the mapping relationship includes a configuration relationship between a PON port to be processed and traffic to be processed.

In some embodiments, querying a mapping relationship between a PON port to be processed and a service to be processed corresponding to the PON port to be processed includes the following steps:

and querying a database of the OLT to which the target OLT slice belongs to obtain a mapping relation between the PON port to be processed and the service to be processed. It should be understood that the mapping relationship is not a simple corresponding relationship, and includes configuration information between the PON port to be processed and the service to be processed.

In step S130, the mapping relationship between the PON port to be processed and the service to be processed is divided into target OLT slices. During the division process, the mapping relation between the PON port to be processed and the service to be processed is not deleted.

In some embodiments, the OLT slice-based configuration method further comprises the steps of:

first, it is determined whether an ONU (Optical Network Unit) corresponding to a PON port to be processed is online.

And then, under the condition that the ONU corresponding to the PON port to be processed is not on line, dividing the mapping relation between the PON port to be processed and the service to be processed into a target OLT slice.

and under the condition that the ONU corresponding to the PON port to be processed is on line, continuously judging whether the ONU corresponding to the PON port to be processed is on line. For example, in a case where the optical network unit ONU corresponding to the PON port to be processed is still on-line within a specified time, the execution of the configuration method is stopped. In some embodiments, the configuration method is suspended from being executed in the event that an ONU corresponding to the PON port to be processed is online.

According to the configuration method based on the OLT slice, the mapping relation between the PON port and the service is redefined, and based on the redefined mapping relation between the PON port and the service, under the condition that the PON port is divided into another OLT slice, the mapping relation between the PON port and the service does not need to be deleted, so that the service interruption time is reduced, the user experience is improved, the operation and maintenance efficiency is improved, and the agility of an access network in a virtualization scene is improved. In addition, compared with a manual configuration mode, the method and the device have the advantages that automatic configuration is realized, the safety of services is guaranteed, and the configuration efficiency is improved.

The configuration method based on the OLT slice is suitable for the scene of an access Network SDN (Software Defined Network), the Network is more and more agile and flexible, meanwhile, the reliability of the service is guaranteed, the operation and maintenance requirements are more conveniently met, and good application and popularization values are achieved in the SDN scene.

Fig. 3 illustrates a flow diagram of an OLT slice-based configuration method according to further embodiments of the present disclosure.

As shown in fig. 3, the configuration method based on the OLT slice includes steps S310 to S340.

In step S310, a configuration instruction generated and issued by a controller corresponding to the OLT is received. The configuration instruction comprises a passive optical network PON port to be processed and a target optical line terminal OLT slice.

In some embodiments, the configuration instructions are generated by a controller corresponding to the OLT to which the target OLT slice belongs. For example, the controller is used to control a plurality of OLTs. The configuration efficiency and the user experience are further improved by the mode that the controller generates and issues the configuration command.

In step S320, a mapping relationship between the PON port to be processed and the service to be processed corresponding to the PON port to be processed is queried.

The mapping relation is from the PON port to be processed to the service to be processed. For example, the mapping relationship includes a configuration relationship between a PON port to be processed and traffic to be processed.

In step S330, it is determined whether an ONU corresponding to the PON port to be processed is online.

In the case that the ONU corresponding to the PON port to be processed is not on-line, step S340 is executed. In step S340, the mapping relationship between the PON port to be processed and the service to be processed is divided into target OLT slices.

If the ONU corresponding to the PON port to be processed is on-line, step S320 is executed. For example, in a case where the optical network unit ONU corresponding to the PON port to be processed is still on-line within a specified time, the execution of the configuration method is stopped. In some embodiments, the configuration method is suspended from being executed in the event that an ONU corresponding to the PON port to be processed is online.

There are no PON ports under OT slice 2. The OLT slice 1 and the OLT slice 2 belong to the same OLT. The mapping relation among the OLT slice, the service and the PON port is that the slice is mapped to the PON port and then mapped to the service.

When the PON port 1 is divided into the OLT slice 2, the mapping relationship between the PON port 1 and the traffic 2 is directly divided into the OLT slice 2.

Compared with the related technology shown in fig. 1, in the configuration method disclosed by the present disclosure, the mapping relationship is re-established without deleting the mapping relationship between the PON port and the service, which has a small influence on the original service of the PON port, reduces the service interruption time, and improves the user experience.
