Description
Technical Field
The invention relates to the field of communication, in particular to a method and a device for monitoring and processing a performance threshold.
Background
In a mobile communication network, an operator evaluates the network quality, the utilization rate of network or service resources and the processing capacity of the network through the analysis of performance measurement data, and can also grasp the operation condition of the network in time through carrying out threshold monitoring on the performance data, and when the performance measurement value exceeds a preset threshold value of the measurement, a corresponding notice containing a performance alarm is reported to the operator, so that the operator can take corresponding measures in time to prevent the network from serious faults and even paralysis.
After the network function is virtualized, there are some changes to the network management architecture and mechanism, and fig. 1 is a management architecture diagram after the network function is virtualized in the related art, as shown in fig. 1, where: a Network Function Virtualization Orchestrator (NFVO) is responsible for lifecycle management of Network services, Network Function Virtualization Infrastructure (NFVI) resource scheduling across Virtual Infrastructure Managers (VIMs), and other Functions. Virtual Network Function Managers (VNFMs) are responsible for lifecycle management of VNFs, each having an associated VNFM. The VIM is responsible for controlling and managing NFVI computation, storage, and network resources. Scaling operations including Scale out \ up and Scale in \ down are arranged in the life cycle of the VNF, and the virtual resources of the VNF can be adjusted.
The traditional Network Management usually adopts a three-layer Management structure including a Network Management (NM) or an Operation Support System (OSS), an Element Management (EM), and an Element. Herein, NM is also referred to as a Network Management System (NMs), and EM is also referred to as an Element Management System (EMs). The interface between the OSS/NM and the EM is a northbound interface and the EM and the network element are southbound interfaces. And the EM completes the configuration of the network element and the acquisition of information such as network element performance, faults, alarms and the like. NM is oriented to network monitoring and analysis of the whole network, and the functions comprise monitoring and operation of network topology, whole network fault warning and acceptance, whole network configuration information acquisition and configuration distribution, end-to-end network performance monitoring and analysis, flow direction and flow distribution monitoring and analysis and the like. After the network function is virtualized, the traditional network manager is responsible for managing the virtual network function application layer.
The processing capacity of a network element in a conventional network is fixed, and for an index that can be used to measure the performance of the network element, a threshold that indicates that the performance processing capacity of the network element is quickly saturated or deficient is relatively fixed, but after network functions are virtualized, the VNF-based network element is expanded or contracted during a life cycle to adjust the virtual resources that it can use, and a change in the available virtual resources may cause a change in the processing capacity of the VNF-based network element for services. If the performance threshold monitoring threshold is not adjusted in time, the performance alarms received by the NM will not correctly reflect the current network performance status or even mislead the operator, because the level of the performance alarms may be too severe or too light and the number of performance alarms may be too large or too small.
In order to solve the problem in the related art that after VNF is scaled down, a performance alarm received by NM cannot correctly reflect the performance status of the current network, an effective solution is not proposed at present.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In this embodiment, a performance threshold monitoring processing method is provided, and fig. 2 is a flowchart of a first performance threshold monitoring processing method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, after receiving a message of completion of VNF expansion or VNF contraction of a virtual network function, a network management NM determines whether to update a current monitoring threshold of a monitored performance measurement item in VNF-based network element current performance threshold monitoring;
step S204, when the judgment result is that the current monitoring threshold needs to be updated, the NM determines a new monitoring threshold of the monitored performance measurement item;
step S206, the NM sends a message carrying the new monitoring threshold to a network element management EM, wherein the message is used for requesting the EM to monitor the monitored performance measurement item according to the new monitoring threshold.
The action executor in the above embodiment may be an Operation-Support System (OSS) in addition to the NM.
As can be seen from the foregoing embodiments, the NM may dynamically adjust the monitoring threshold according to the VNF expansion or VNF contraction condition, that is, determine the new monitoring threshold, so that the EM monitors the performance of the network element according to the accurate monitoring threshold, and ensures that the performance threshold monitoring after virtualization can correctly reflect the performance state of the current network, thereby solving the problem that the performance alarm received by the NM cannot correctly reflect the performance state of the current network after VNF contraction and expansion in the related art, and further achieving the effect of accurately monitoring the performance state of the current network.
In an alternative embodiment, the NM may receive the VNF expansion or VNF contraction completion message in various ways, for example, a message indicating that the VNF expansion or VNF contraction is completed may be received from the EM and/or the network function virtualization orchestrator NFVO. It should be noted that the above-mentioned receiving manner is only an example, and other manners may also be adopted to receive the message indicating that the VNF expansion or the VNF contraction is completed.
In an alternative embodiment, the NM determining whether to update the current monitoring threshold of the monitored performance measure item in the current performance threshold monitoring of the VNF-based network element comprises: after the NM determines that the VNF is expanded or contracted, whether a service processing capability (the service processing capability may also be referred to as a service index) corresponding to the monitored measurement item of the network element changes; determining that the current monitoring threshold needs to be updated under the condition that the service processing capacity is determined to be changed; determining that the current monitoring threshold does not need to be updated under the condition that the service processing capacity is determined not to be changed; when it is determined that the monitoring threshold needs to be updated, the updating may be performed as follows: and the NM determines the new monitoring threshold according to the relation between the business processing capacity and the monitoring threshold and the changed business processing capacity. In this embodiment, the service processing capability and the monitoring threshold corresponding to the monitored measurement item of the network element satisfy a certain correspondence, and when the service processing capability corresponding to the monitored measurement item of the network element is changed, the monitoring threshold for monitoring the network element also needs to be adjusted correspondingly to adapt to the changed service processing capability.

When the first request message and the second request message are sent to the EM, the first request message may be sent first, and then the second request message is sent, or the second request message may be sent first, and then the first request message is sent, or the first request message and the second request message may be sent simultaneously.

Wherein, the NM in the above embodiment may also be replaced by OSS. In the above embodiment, the EM may monitor the monitored performance measurement item according to a new monitoring threshold sent by the NM, and the new monitoring threshold is determined again by the NM after the completion of the VNF companding. Therefore, the performance threshold monitoring after virtualization can correctly reflect the performance state of the current network, the problem that performance alarms received by NM cannot correctly reflect the performance state of the current network after VNF scaling in the related art is solved, and the effect of accurately monitoring the performance state of the current network is achieved.
In an optional embodiment, before the EM receives the message carrying the new monitoring threshold from the NM, the method further includes: the EM receives a notification message from a Virtual Network Function Manager (VNFM) for indicating completion of the VNF expansion or VNF contraction; the EM transmits a message indicating completion of the VNF expansion or VNF contraction to the NM according to the notification message. In this embodiment, the modification of the monitoring threshold may be triggered by the EM. In practical applications, the processing may be triggered by the EM, and may also be triggered by the NFVO, that is, the NFVO sends the processing message to the NM after determining that the VNF is expanded or contracted.
In an optional embodiment, the receiving, by the EM, the message carrying the new monitoring threshold from the NM includes: the EM receives a first request message and a second request message from the NM, wherein the second request message carries the new monitoring threshold value; the monitoring, by the EM, of the monitored performance measurement item according to the new monitoring threshold includes: and the EM deletes the original performance threshold monitoring task according to the first request message and establishes a new performance threshold monitoring task corresponding to the new monitoring threshold according to the second request message. When receiving the first request message and the second request message from the NM, the NM may receive the first request message first and then receive the second request message, or may receive the second request message first and then receive the first request message, or may receive the first request message and the second request message at the same time.
