Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for detecting a service affected by a network element failure, including the following steps:
step S101, setting partial network elements in the target area as invalid network elements.
The network element data may be basic data such as network elements uploaded through an existing interface of a network manager by connecting an evaluation tool to the network manager to be detected. If the network manager is used as a plug-in, the basic data such as network elements in the network manager can be directly used.
The target area is an area where the user needs to evaluate whether the service is affected by the failure of the network element. The target area is an area selected by a user according to the need, the system provides default areas comprising a backbone layer, an access layer and a convergence layer, the user can add the network element into different areas according to different actual functions of the network element, and one or more layers can be selected as the target area at the same time for evaluation. The user can also create a new area, and the specific size and position of the target area can be selected by the user according to the needs. For example, the user selects an access layer and a convergence layer as target areas, and sets part of network elements in the access layer and the convergence layer as failure network elements.
And selecting a part of network elements to be set as invalid network elements in the target area. The target area may be an area included in the target area, the selecting a part of network elements to be failure network elements may be selecting by a user according to needs, the selecting a key point network element to be failure network elements may be network elements with more service, for example, network element bridge nodes and backbone network elements.
In addition, the failed network element may be that the network element is not able to function properly. Setting a part of network elements as failure network elements may be setting the part of network elements, so that the part of network elements cannot work normally.
Step S102, inquiring a service set passing through the failure network element in the target area, and judging whether the service set is influenced by the failure network element or not according to each service in the service set.
The service may be TDM or ethernet service, the service set may be all the services passing through the failure network element in the target area, and the query is performed by taking all the services passing through the failure network element in the target area as a query target. The query mode may be to query whether all the services in the area pass through the failure network element one by one, and screen out all the services passing through the failure network element to form a service set; or directly querying all the services passing through the failed network element, and forming the services passing through the failed network element into a service set.
The determining whether the service is affected by the failed network element for each service in the service set may be determining whether the service is affected by the failed network element one by one in the service set. After judging one service, continuing to judge the next service, and ending the judgment when all the services in the service set passing through the failure network element are judged. For example, there are 100 total service sets passing through the failed network element in the target area, the 100 services are judged, when 98 service sets are judged, two service sets are not judged, the 99 th service set is continuously judged, after the 99 th service set is judged, one service set is not judged, the judgment is continuously carried out until all 100 service sets in the service set are judged, and the judgment is finished.
In addition, the influence of the failed network element on the service passing through the failed network element may be that the service passing through the failed network element is interrupted, and after the service is interrupted, the service cannot be continued without any processing; the service may be not interrupted but have an influence on transmission performance, the influence may be an influence on transmission performance, a delay, a stability decrease, or other influences, where the service may still be performed, and the specific influence generated above may be one or more influences, and the specific influence generated in this embodiment is not limited. For example, a service passing through a failed network element is affected by the failed network element to generate service delay, and stability is reduced. This is merely an example, and the present embodiment is not limited thereto.
And step S103, acquiring the service affected by the failure network element in the target area according to the judging result.
The determination result may be a determination result obtained by determining, in step S102, whether the service is affected by the failed network element for each service in the service set. The judging result may include that the service in the service set is affected by the failed network element and is interrupted, and the service in the service set is affected by the failed network element but is not interrupted, or may be other more specific affecting results. The judging result may further include each service affected by the failed network element in the service set passing through the failed network element in the target area and the influence of each service correspondingly.
The obtaining the service affected by the failed network element in the target area may be obtaining all the services affected by the failed network element in the service set passing through the failed network element in the target area and the corresponding affected services according to the determination result in step S102.
The acquiring process may be that each time a service affected by the failed network element is judged, the service and the corresponding affected service are acquired, until all the services passing through the failed network element in the service set are judged, all the services affected by the failed network element and the corresponding affected service are acquired. For example, a total of 100 services passing through the failure network element in the service set are judged, the 1 st service is affected, the 1 st affected service and the corresponding affected service are obtained, the 2 nd service is judged, the 2 nd affected service and the corresponding affected service are obtained, the next service is judged until all the 100 services are judged, and the affected service and the corresponding affected service in the 100 services are obtained. This is merely an example, and the present embodiment is not limited thereto.
The acquiring process may also be that after all the services in the service set that pass through the failure network element are judged, the affected service in the service set and the corresponding affected service are acquired. For example, there are 100 services passing through the failed network element in the service set, and after the 100 services in the service set are judged in sequence, the affected service in the 100 services and the corresponding affected service are obtained. This is merely an example, and the present embodiment is not limited thereto.
In this embodiment, the above method may be applied to a PDN device.
In this embodiment, a part of network elements in a target area are set as failure network elements, a service set passing through the failure network elements in the target area is queried, whether the service is affected by the failure network elements is judged for each service in the service set, and the service affected by the failure network elements in the target area is obtained according to a judgment result. Thus, the efficiency of detecting that the network element failure affects the service can be improved.

Step S205, it is determined that the currently judged service is affected by the failed network element without interruption.

If the pseudo wire protection exists, inquiring a working pseudo wire route and a protection pseudo wire route, and judging whether the working pseudo wire route and the protection pseudo wire route pass through the failure network element at the same time. If the working pseudo-line route and the protection pseudo-line route do not pass through the failure network element at the same time, the current judging service can be determined to be influenced by the failure network element without interruption.
The whether the working pseudowire route and the protection pseudowire route pass through the failure network element at the same time may be whether the working pseudowire route and the protection pseudowire route pass through the failure network element at the same time. For example, both the working pseudowire route and the protection pseudowire route pass through the failed network element. The working pseudowire route and the protection pseudowire route do not pass through the failure network element at the same time, and either one of the working pseudowire route and the protection pseudowire route or both routes pass through the failure network element. For example, the working pseudowire route passes through the failed network element, and the protection pseudowire route does not pass through the failed network element.
The influence may be an influence on transmission performance, the influence on transmission performance may be a delay or a decrease in stability, or may be other influence, and the generated influence may be one or more influences, which is not limited in this embodiment.

The route passing through the working tunnel and the protection tunnel at the same time may be that the route passing through the working tunnel and the protection tunnel both pass through the failure network element, and the route passing through the failure network element at different times may be that only one of the route passing through the working tunnel and the protection tunnel passes through the failure network element or neither of them passes through the failure network element.
