detailed description

In the following description, for purposes of illustration and description, reference However, it will be apparent to those skilled in the art that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the application.

Referring to FIG. 2, FIG. 2 is a flowchart of a first embodiment of a monitoring method of the present application. The first embodiment of the monitoring method of the present application is described from the perspective of a network function virtualization supervision terminal, and the monitoring method includes the following steps:

S201: Obtaining a monitoring strategy

The network function virtualization supervisor acquires a pre-configured monitoring policy. The monitoring strategy includes the correspondence between the resource usage information of the VNF to be monitored and the fault handling method. The resource usage information of the VNF includes: an operation indicator of the resource used by the VNF and an indicator threshold when a service failure may occur, and the fault processing method is a method for solving the service failure. The network function virtualization supervision terminal may be dedicated hardware or a management program, which is not limited herein.

S202: Form a monitoring requirement according to the monitoring policy, and send a monitoring requirement to the virtualization infrastructure management end.

In this embodiment, the virtualization infrastructure management terminal refers to a VIM. In general, monitoring requirements are based on resource usage information of VNFs that need to be monitored in the monitoring strategy. A VNF can run on a virtual machine; or a VNF includes at least two virtual network function components (VNF Components, VNFC), each running on a virtual machine. The resources used by the VNF may refer to virtual resources used by the VNF or VNFC, or may refer to corresponding hardware resources. The resources used by the VNF are monitored by VIM.

S203: Receive VNF abnormality information detected by the virtualization infrastructure management end in response to the monitoring requirement

The VIM responds to the monitoring requirements and monitors the resources used by the VNF. When an abnormality is detected, the abnormal information is sent to the network function virtualization supervision terminal.

S204: Send a fault processing method corresponding to the abnormal information to the virtualization infrastructure management terminal or the VNF for fault processing.

Find the fault handling method corresponding to the abnormal information in the monitoring policy, and send the fault processing method to the VIM or the VNF for fault processing. Generally, the exception is solved by switching backups and skipping the abnormal VNF. The VNF used for fault handling is not an abnormal VNF.

In the foregoing solution, the service fault that may occur in the VNF and the resource abnormality used in the fault are associated in advance, and the corresponding service fault processing method is given, and the resource information used in the VNF may be faulty and the corresponding fault processing method is performed. The association is stored in the monitoring policy. The network function virtualization supervisor acquires the monitoring policy and notifies the virtualization infrastructure management terminal to monitor the resources used by the VNF according to the monitoring policy; when the abnormal information is detected, the corresponding fault processing method is processed, so that there is no EMS. The VNF service fault monitoring and processing can be completed without reporting the OSS, improving the fault handling efficiency and reducing the business impact caused by the fault.

Please refer to FIG. 3. FIG. 3 is a structural timing diagram of a second embodiment of the monitoring method of the present application. The second embodiment of the monitoring method of the present application is based on the first embodiment of the monitoring method of the present application, and is implemented by NFVO31. The network function virtualization supervision terminal is responsible for monitoring and processing VNF faults.

The NFVO 31 can receive and save the monitoring policy delivered by the OSS 30, or read the monitoring policy from the Network Service Descriptor (NSD) 311 and/or the Virtualized Network Function Descriptor (VNFD) 312. The NSD311 includes information such as VNF information and link information constituting the network service, dependencies between the VNFs, parameters to be monitored by the VNF runtime, and monitoring policies of the VNF. VNFD312 includes information such as VNF composition, monitoring parameters, deployment specifications, and VNF monitoring policies. NSD311 and VNFD 312 are stored in NFVO31. VNFD312 is open to VNFM32 and can be read by VNFM32.

NFVO31 forms monitoring requirements according to the monitoring strategy and sends the monitoring requirements to VIM33; VIM33 responds to the monitoring requirements and sends the detected abnormal information to NFVO31; NFVO31 checks the monitoring strategy after receiving the abnormal information. Find the fault handling method corresponding to the exception information. Since the NFVO31 cannot directly connect to the NFV34 in the existing NFV architecture, the NFVO31 needs to send a fault handling method to the VNF34 for fault handling through the VNFM32 to solve the abnormality, or directly send a fault handling method to the VIM33 to solve the abnormality.

Please refer to FIG. 4. FIG. 4 is a structural timing diagram of a third embodiment of the monitoring method of the present application. The third embodiment of the monitoring method of the present application is based on the first embodiment of the monitoring method of the present application, and is based on NFVO41 and The VNFM42 is combined as a network function virtualization supervisor to monitor and process VNF faults. Among them, VNFM42 is responsible for fault monitoring, and NFVO41 is responsible for fault handling.

NFVO41 can receive the monitoring policy delivered by OSS40, and then forward the monitoring policy in the monitoring policy to VNFM42, which only saves the processing policy, VNFM42 saves the received monitoring policy; or NFVO41 reads the monitoring policy from NSD411, and then monitors the policy. The monitoring policy is forwarded to VNFM42, which stores the received monitoring strategy; or NFVO41 reads the processing strategy from NSD411 and/or VNFD412, and VNFM42 reads the monitoring policy from VNFD412. The monitoring strategy further includes a numbering, the monitoring strategy includes a number and a corresponding resource usage information of the VNF to be monitored, and the processing strategy includes a number and a corresponding fault handling method.

The VNFM42 generates monitoring requirements based on the monitoring strategy and sends monitoring requirements to the VIM 43; the VIM 43 responds to the monitoring request to send the detected abnormal information to the VNFM 42; the VNFM 42 forwards the abnormal information to the NFVO 41. The NFVO 41 receives the abnormal information forwarded by the VNFM 42 and searches for a corresponding fault processing method in the processing strategy. The NFVO 41 directly sends a fault processing method to the VIM 43 or sends a fault processing method to the VNF 44 through the VNFM 42 to resolve the abnormality.

Referring to FIG. 5, FIG. 5 is a structural sequence diagram of a fourth embodiment of the monitoring method of the present application. The fourth embodiment of the monitoring method of the present application is based on the first embodiment of the monitoring method of the present application, and is implemented by VNFM52. The network function virtualization supervision terminal is responsible for monitoring and processing VNF faults.

The VNFM52 can receive the monitoring policy forwarded by the NFVO51 and save the monitoring policy sent by the NFVO 51 by receiving the monitoring policy delivered by the OSS 50 or the monitoring policy read from the NSD 511. The VNFM 52 can also read the monitoring policy from the VNFD 512.

The VNFM52 generates monitoring requirements according to the monitoring policy and sends the monitoring requirements to the VIM53. The VIM53 responds to the monitoring requirements and sends the detected abnormal information to the VNFM52. After receiving the abnormal information, the VNFM52 searches for the fault handling method corresponding to the abnormal information in the monitoring policy. The VNFM 52 can send a fault handling method to the VIM 53 via the NFVO 51, or directly send a fault handling method to the VNF 54 for fault handling.

The second embodiment to the fourth embodiment respectively describe the combination of NFVO, NFVO, and VNFM, and the VNFM serves as a virtualization function of the network function virtualization, and is responsible for monitoring and processing the VNF fault. Among them, NFVO, VNFM, VIM points Not an integral part of MANO. It can be seen that MANOs including NFVO, VNFM, and VIM can perform closed-loop processing of VNF faults, including fault discovery, correlation, and processing.

In an embodiment of the monitoring method of the present application, the resource usage information of the VNF to be monitored includes: an indicator of the VNF usage resource, a corresponding threshold, and a requirement for determining an abnormality.

The VNF resource usage indicator is at least one of the CPU usage rate, the memory usage rate, the hard disk read/write rate, and the on/off, delay, and bandwidth occupancy of the link used by the VNF. The CPU usage, memory usage, and hard disk read/write rate of the computer used by the VNF may be the operational indicators of the virtual machine used by the VNF or VNFC, or may be the operational indicators of the actual computer corresponding to the virtual machine. The on/off, delay, and bandwidth usage of the link used by the VNF may be an operation indicator of a link between the current VNF and other VNFs, or may be an operation indicator of a link between different VNFCs within the current VNF.

The threshold is a threshold for determining the corresponding indicator of the monitored VNF failure. For the special indicator of link continuity, the value of the indicator can be defined as 1 and 0, 1 for connectivity, 0 for disconnection, or vice versa, threshold is also 1 or 0. The requirement for determining the abnormality refers to the relationship between the value of the monitored indicator and the corresponding threshold, and determines that the VNF has a service failure. For example, the given monitoring indicator is the CPU occupancy rate, the threshold is 80%, and the requirement is greater than, When the CPU occupancy is detected to be greater than 80%, it is determined that the VNF has a service failure. When the number of indicators to be monitored is at least two, the requirement to determine the anomaly also includes the logical relationship (and, or, and) between the different indicators. This embodiment can be combined with any of the above embodiments.

In an embodiment of the monitoring method of the present application, the fault processing method includes: notifying the virtualization infrastructure management terminal to update a Network Forwarding Path (NFP) and/or notifying the VNF for fault processing to modify its business logic. This embodiment can be combined with any of the above embodiments.

The NS is composed of multiple VNFs. One service of the NS can be completed by using several VNFs. The VNFs are linked by virtual links (VL links), and each VNF has several connection points (Connection Point, CP) is used to link with other VNFs. NFP specifies the characteristics of a certain traffic flow (such as the value of the packet header) and its forwarding path. In the present application, the primary concern is the forwarding path defined by the NFP, that is, the forwarding path actually passed by the data flow during the service running, and the forwarding path is described by the passed CP.

Please refer to FIG. 6. FIG. 6 is a schematic diagram of processing a fault by updating an NFP in an embodiment of the monitoring method of the present application. If the NS is designed with the active/standby solution in mind, for example, the NFP2 in the figure is the alternate path of the NFP1, when the VNF2 fails, the fault of the VNF2 can be solved by migrating the service flow of the NFP1 to the NFP2. This can be done by updating NFP. Since NFP is part of NS, updating NFP requires NFVO to modify the NFP description in NS and notify VIM to modify the underlying logic to implement the actual NFP update. In Figure 6 NFVO modifies NFP1: CP11, CP13, CP21, CP22, CP41, CP43 to NFP2: CP11, CP12, CP31, CP32, CP41, CP43, and then notifies VIM to update NFP, and completes switching backup VNF.

Please refer to FIG. 7. FIG. 7 is a schematic diagram of processing a fault in a manner of notifying a VNF for fault handling to modify its business logic in one embodiment of the monitoring method of the present application. If the VNF5 for fault handling is a virtual network element with similar packet distribution function, it can determine the direction of the data packet flowing through it. Then, the VNF5 can be solved by notifying the VNF5 to modify the service logic. That is, VNF5 is notified to migrate the data forwarding path from the failed VNF6 to the backup VNF7, and the data forwarding path is changed from VNF5->VNF6->VNF 8 to VNF 5->VNF 7->VNF 8. In the current standard, NFVO cannot directly connect to VNF5, so it is necessary to notify VNF5 through VNFM.

In one embodiment of the monitoring method of the present application, the monitoring policy further includes a corresponding VNF identification and/or fault description. The VNF identification and fault description can facilitate the viewing and management of the monitoring strategy, and its presence does not affect the monitoring and processing of VNF faults. The monitoring requirements formed according to the monitoring policy may further include a corresponding VNF identifier and/or fault description in addition to the resource usage information including the number and the VNF to be monitored. This embodiment can be combined with any of the above embodiments. In addition, the monitoring strategy can also include a number.

Please refer to Table 1. Table 1 is an example table of monitoring policies in an embodiment of the monitoring method of the present application. The content of the monitoring policy in Table 1 is only an indication, and is not necessarily related to the actual monitoring strategy that may exist. The monitoring policy in Table 1 includes the number, corresponding VNF identifier, and fault description, and may include only one or none of them.

Specifically, the method includes the following steps: S801: forming a monitoring requirement according to the monitoring policy; and S802: repeatedly transmitting the monitoring requirement to the virtualization infrastructure management end within a specified time. After receiving the monitoring requirement, the VIM monitors the VNF resource to be monitored, and sends the abnormal information to the network function virtualization supervision terminal when the abnormality is detected. When no abnormality is detected, only the abnormal information is sent. It is also possible to directly send the monitored information to the network function virtualization supervision terminal, and the network function virtualization supervision terminal determines whether it is different.

S903: Receive an exception information of the VNF actively sent by the virtualization infrastructure management terminal in response to the subscription request to detect an abnormality.

The VIM responds to the subscription request and monitors the resources used by the VNF to be monitored according to the monitoring frequency during the monitoring time. When the monitored information meets the requirements, that is, when the VNF is abnormal, the virtual function is actively activated to the network function by means of notification. The supervisor sends the abnormal information of the VNF, and the network function virtualization supervisor receives the abnormal information. The abnormal information includes resource usage information of the VNF to be monitored. This embodiment can be combined with any of the above embodiments other than the embodiment corresponding to FIG.

S1001: Form monitoring requirements according to the monitoring strategy, and send monitoring requirements to the proposed infrastructure management terminal

Monitoring requirements can further include monitoring frequency.

S1002: Send a subscription request for the associated monitoring requirement to the virtualization infrastructure manager
