Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a virtual network function management method, which is applied to a proxy device. Referring to fig. 1, fig. 1 is a flowchart of a method for managing virtual network functions according to a first embodiment of the present invention, which includes the following steps:
step S101: and receiving a life cycle operation information message which is sent by the virtual network function management device and is used for managing the virtual network function.
The life cycle operation information comprises virtual network function instantiation, virtual network function expansion, virtual network function contraction and virtual network function termination; wherein, the termination of the virtual network function is one of the virtual network function reduction, and the termination can be regarded as full reduction. In this embodiment, the lifecycle operation information is instantiated for the virtual network function, and includes an initialization configuration request, where the initialization configuration request is used to initialize the configuration information of the virtual network function, so that the virtual network function has an initial lifecycle.
It should be noted that the lifecycle operation information includes unique identification information of at least one virtual network function, where the unique identification information is used to determine a target virtual network function instantiated by the virtual network function.
Step S102: and determining the configuration operation required by the network management device according to the life cycle operation information message for managing the virtual network function.
Step S103: and sending a configuration operation information message for executing the configuration operation to the network management device.
The agent device receives a life cycle operation message which is sent by the virtual network function management device and used for managing the virtual network function, and determines the configuration operation which needs to be carried out by the network management device according to the life cycle message, so that the life cycle operation message becomes a transfer device between the virtual network function management device and the network management device, and provides support for the virtual network function management device to control the network management device, thereby further realizing the monitoring management of the interactive flow between the virtual network function management device and the network management device.
The following describes implementation details of the virtual network function management method according to this embodiment in detail, and the following is only provided for easy understanding and is not necessary to implement this embodiment.
For clarity of the illustration, all response steps in the illustration are identified by dashed lines. Referring to fig. 2, fig. 2 is a flowchart of instantiating a virtual network function according to a second embodiment of the present invention, which specifically includes:
step 101: the Virtual Network Function Manager 21 (VNFM) sends an authentication request to the authentication module 21.
Specifically, the proxy device (not shown) includes an authentication module 21, and the authentication module 21 is configured to verify identity information of the virtual network function management device that sent the request. Before executing step 103, the virtual network function management apparatus 1 needs to send an authentication request to the proxy apparatus, where the authentication request is used for the proxy apparatus to verify whether the identity information of the virtual network function management apparatus is valid, and after verifying the identity information of the virtual network function management apparatus and obtaining a verification result, the authentication module 21 executes step 102.
In the present embodiment, the authentication module 21 adopts an authentication mechanism based on jwt (json Web token). It should be noted that, in other embodiments, the authentication module may also use an authentication mechanism based on Session ID.
Step 102: the authentication means 21 sends an authentication response to the virtual network function management means 1.
Specifically, the authentication device 21 transmits the verification result to the virtual network function management device 1. When the verification result is that the identity information of the virtual network function management device is invalid, the agent device 21 does not receive the life cycle operation information sent by the virtual network management device 1; when the verification result is that the identity information is valid, the authentication module sends a token value (token) to the virtual network function management device 1, the network virtual function management device 1 stores the token value (token), and step 103 is executed.
Step 103: the virtual network function management device 1 sends an initialization configuration request to the lifecycle module 23.
Specifically, the agent apparatus includes a lifecycle synchronization module 23, and the lifecycle synchronization module 23 is configured to receive lifecycle operation information sent by the virtual network function management apparatus 1.
It should be noted that the initial configuration request includes a token value (token) for the authentication module 21 to confirm that the identity information of the sender of the initial configuration request is valid identity information. Each request of the virtual network function management apparatus 1 includes a token value (token), and the token value (token) is stored in a request header of any request.
Step 104: the life cycle synchronization module 23 sends an authentication request to the authentication module 21.
Specifically, the lifecycle synchronization module 23 sends the token value (token) in the initialization configuration request to the authentication module 21, and the authentication module 21 verifies the token value to obtain a verification result and then executes step 105.
Step 105: the authentication module 21 sends an authentication response to the life cycle synchronization module 23.
Specifically, the life cycle synchronization module 23 receives the verification result sent by the authentication module 21, and if the verification result is that the identity information is valid, step 106 is executed; and when the verification result is that the identity information is invalid, the initialization configuration request is not executed.
Step 106: lifecycle module 23 sends a configuration operation message to operation maintenance module 31 for performing a configuration update.
Specifically, the network management apparatus (not shown) includes an Operation and maintenance module 31 (OMM), and in this embodiment, the Operation and maintenance module 31 is configured to modify dynamic configuration information of the virtual network function. The life cycle module 23 determines the configuration operation corresponding to the initialization configuration request as the initialization configuration information according to the corresponding relationship between the life cycle operation information and the configuration operation, and sends a configuration operation message for executing the initialization configuration information to the operation maintenance module 31, and the operation maintenance module 31 executes the initialization configuration information operation after receiving the configuration operation message.
In addition, the initialization configuration request includes configuration information, and the configuration information is used for determining the life cycle of the instantiated virtual network function. When the lifecycle module 23 sends a configuration operation message for executing the initialization configuration message to the operation maintenance module 31, the configuration information is also sent to the operation maintenance module 31, and the operation maintenance module 31 synchronizes the configuration by modifying the dynamic configuration parameters of the virtual network function, thereby implementing instantiation of the virtual network function.
Step 107: the lifecycle synchronization module 23 sends an initialization configuration response to the virtual network function management apparatus 1.
Specifically, after the lifecycle module 23 sends a configuration operation message for executing the initialization configuration information to the operation maintenance module 31, the operation maintenance module 31 confirms the execution of the configuration operation and feeds back the execution confirmation message, and after receiving the execution confirmation message, the lifecycle synchronization module 23 sends the execution confirmation message to the virtual network function management apparatus 1, completes the response of the initialization configuration request, and declares that the initialization configuration operation is being executed.
Step 108: the virtual network function management apparatus 1 transmits a progress acquisition request to the progress tracking module 22.
Specifically, the agent device further includes a progress tracking module 22, which is configured to obtain the execution progress of the currently configured operation of the operation maintenance module 31. After receiving the execution confirmation message, the virtual network function management apparatus 1 sends a progress acquisition request to the progress tracking module 22 for querying the execution progress of the configuration operation.
It should be noted that the first delay time may be preset, and after receiving the execution confirmation message, the virtual network function management apparatus 1 waits for the preset delay message and then sends the progress acquisition request to the progress tracking module 22. The delay time is set according to the shortest time of the initialization configuration information in the actual operation condition, and the set delay time can reduce the cycle number of the subsequent progress acquisition request and reduce the operation burden of the system.
Step 109: the progress tracking module 22 sends an authentication request to the authentication module 21.
Specifically, the progress tracking module 22 sends the token value in the progress obtaining request to the authentication module 21, the authentication module 21 verifies the token data to obtain a verification result, and step 110 is executed.
It should be noted that the request header of each request of the virtual network function management device 1 carries a token value, each request needs to be authenticated, and when the token value verification result is valid, the proxy device executes the request sent by the virtual network function management device.
Step 110: the authentication module 21 sends an authentication response to the progress tracking module 22.
Specifically, the authentication module 21 sends the verification result of the token value to the progress tracking module 22, and completes the response of the authentication request. When the verification result is that the token value is valid, executing step 111; and when the token value is invalid as a verification result, the progress acquisition request is not executed.
Step 111: the progress tracking module 22 obtains whether the service is fully initiated.
Specifically, the progress tracking module 22 sends a message for inquiring the execution progress of the configuration operation to the operation maintenance module 31, and when the execution of the configuration operation is completed, the service is considered to be all started.
Step 112: the operation and maintenance module 31 feeds back the service start-up progress.
Specifically, the operation maintenance module 31 feeds back the service start progress after receiving the message for querying the configuration operation execution progress. In this embodiment, the service initiation schedule is incomplete or completed. It should be noted that, in other embodiments, a specific value of the execution progress of the configuration operation is further included. The progress tracking module 22, upon receiving the service initiation progress, performs step 113.
Step 113: the progress tracking module 22 sends a progress acquisition response to the virtual network function management device.
Specifically, the progress tracking module 22, after receiving the service start progress sent by the operation and maintenance module 31, sends the service start progress to the virtual network function management apparatus 1, and completes the response of the progress acquisition request.
It should be noted that, when the service activation schedule received by the virtual network function management apparatus 1 is not completed, the steps 108 to 113 are executed in a loop until the service activation schedule received by the virtual network function management apparatus 1 is completed. When the service activation schedule received by the virtual network function management apparatus 1 is completed, step 114 is executed.
It should be noted that, in this embodiment, when the virtual network function management apparatus 1 receives the service start schedule, the schedule acquisition request is retransmitted after waiting for the preset second delay time. The second delay time is less than the first delay time, so that the virtual network function instantiation efficiency is improved; furthermore, the subsequent progress acquisition request still requires the verification of the token value by the authentication module 21.
The monitoring of the execution progress of the current configuration operation is realized by inquiring the execution progress of the configuration operation, and the next life cycle operation information is sent after the execution of the current configuration operation is finished, so that the confusion of the execution of the configuration operation caused by sending the next life cycle operation information when the execution of the previous configuration operation is not finished is avoided.
Step 114: the virtual network function management apparatus 1 transmits a lifecycle change notification to the lifecycle synchronization module 23.
Step 115: lifecycle synchronization module 23 sends the received lifecycle change notification to operation and maintenance center 32.
Specifically, the network management device further includes an Operation and Maintenance Center (OMC) for receiving the lifecycle change notification, thereby implementing the supervision of the lifecycle change of the virtual network function. The operation and maintenance center 32 records the life cycle change of the virtual network function when receiving the life cycle change notification.
In this embodiment, when the lifecycle operation information is instantiated as a virtual network function, the operation and maintenance center records the newly added virtual network function and the lifecycle of the newly added virtual network function.
A third embodiment of the present invention relates to a method for managing a virtual network function. The third embodiment is substantially the same as the second embodiment, and mainly differs in that: in a second embodiment, the lifecycle operational information is instantiated for a virtual network function. In the third embodiment of the present invention, the lifecycle operation information is the expansion of the virtual network function. Furthermore, it will be understood by those skilled in the art that the third embodiment of the present invention has the same or similar parts as the second embodiment, and the technical details already mentioned in the second embodiment are still valid in the third embodiment.
For the sake of simplicity in flow expression, the steps of authentication request and authentication response are omitted in the following flow; meanwhile, in order to reduce repetition, technical details of the second embodiment that are the same as or similar to those of the present embodiment are not repeated in the present embodiment. Referring to fig. 3, fig. 3 is a flowchart illustrating manual capacity expansion of a virtual network function according to a third embodiment of the present invention, where the contents of steps 208 to 213 in the third embodiment of the present invention are the same as or similar to those of steps 108 to 115 in the second embodiment, and are not repeated here, and the differences between the third embodiment of the present invention and the second embodiment of the present invention are specifically embodied in the following steps:
step 201: the virtual network function management apparatus 1 transmits a pre-expansion notification to the lifecycle synchronization module 23.
Specifically, the virtual network function management apparatus 1 sends a pre-expansion notification to the lifecycle synchronization module 23 before sending the lifecycle expansion notification, where the pre-expansion notification is used to notify the operation and maintenance center 32 and the operation and maintenance module 31 to perform corresponding preparation work in advance.
In this embodiment, the pre-expansion notifications sent to the operation and maintenance center 32 and the operation and maintenance module 31 are sent separately; fig. 3 does not show sending the pre-expansion notification of the operation and maintenance module. It should be noted that, in other embodiments, the pre-expansion notification sent to the operation and maintenance center and the operation and maintenance module is sent separately.
In this embodiment, the time point of the pre-expansion notification is determined manually. In another embodiment, the time point of the pre-expansion notification is determined by the virtual network function management device.
Step 202: lifecycle synchronization module 23 sends the received pre-expansion notification to operation and maintenance center 32.
Specifically, the life cycle synchronization module 23 sends the received pre-expansion notification to the operation and maintenance module 31 and the operation and maintenance center 32, and the operation and maintenance center 32 and the operation and maintenance module 31 perform corresponding pre-preparation work according to the pre-expansion notification.
Step 203: the virtual network function management apparatus 1 transmits a lifecycle expansion notification to the lifecycle operation module 23.
Specifically, the life cycle capacity expansion notification includes identification information of at least one virtual network function and configuration information corresponding to the identification information of the virtual network function, and the configuration information includes a life cycle used for operating the life cycle of the specific virtual network function.
Step 204: the lifecycle synchronization module 23 sends the received lifecycle capacity expansion notification to the operation and maintenance module 31.
Step 205: the operation maintenance module 31 performs a configuration update operation.
Specifically, the operation and maintenance module 31 modifies the configuration information corresponding to the virtual network function according to the received identification information of at least one virtual network function and the configuration information corresponding to the identification information of the virtual network function, so as to operate the life cycle of the virtual network function and complete the capacity expansion of the virtual network function.
Step 206: the operation and maintenance module 31 sends a life cycle capacity expansion response to the life cycle synchronization module 23.
After the operation maintenance module 31 confirms to execute the configuration updating operation, the operation maintenance module 31 needs to send a life cycle capacity expansion response corresponding to step 204 to the life cycle synchronization module 23;
step 207: the lifecycle synchronization module 23 sends a lifecycle expansion response to the virtual network function management apparatus 1.
The lifecycle synchronization module 23 transmits the lifecycle expansion response corresponding to step 203 to the virtual network function management apparatus 1.
Step 214: the operation and maintenance center 32 updates the management object.
Specifically, the lifecycle change notification includes identification information of at least one virtual network function and configuration information corresponding to the identification information of the virtual network function, where the configuration information is configuration information after the lifecycle of the virtual network function changes. After receiving the lifecycle change notification, the operation and maintenance center 32 modifies the configuration information of the corresponding virtual network function recorded by the operation and maintenance center 32.
A fourth embodiment of the present invention relates to a virtual network function management method. The fourth embodiment is substantially the same as the third embodiment, and mainly differs therefrom in that: in the third embodiment, the lifecycle operation to be implemented is virtual network function expansion; in the fourth embodiment, the lifecycle operations to be implemented are virtual network function reduction.
Referring to fig. 4, fig. 4 is a flowchart illustrating a manual capacity reduction process of a virtual network function according to a fourth embodiment of the present invention, where steps 301 to 304 in the fourth embodiment of the present invention are the same as or similar to steps 201 to 202 in the third embodiment, steps 308 to 323 in the fourth embodiment are the same as or similar to steps 206 to 214 in the third embodiment, and no further description is given here, and the difference between the third embodiment of the present invention and the second embodiment of the present invention is embodied in the following steps:
step 305: and closing the corresponding service.
Specifically, the pre-condensed content notification received by the operation and maintenance module 31 includes identification information of at least one virtual network function. After receiving the pre-capacity reduction notification, the operation and maintenance module 31 needs to close the service process of the virtual network function corresponding to the pre-capacity reduction notification.
Step 306: the operation and maintenance module 31 sends a pre-condensed volume response to the life cycle synchronization module 23.
Specifically, after the operation maintenance module 31 confirms to execute the closing operation, the operation maintenance module 31 needs to send the pre-capacity reduction response corresponding to step 304 to the life cycle synchronization module 23;
step 307: the lifecycle synchronization module 23 sends a lifecycle expansion response to the virtual network function management apparatus 1.
Specifically, the lifecycle synchronization module 23 sends the lifecycle expansion response corresponding to step 303 to the virtual network function management apparatus 1. In this embodiment, the virtual network function management apparatus 1 needs to acquire the execution progress of step 301, and can send the lifecycle management notification to the lifecycle synchronization module 23 only after the service process of the virtual network function is completely closed.
A fifth embodiment of the present invention relates to a method for managing virtual network functions, and the fifth embodiment is substantially the same as the fourth embodiment, and mainly differs in that: in the fifth embodiment, the operation and maintenance module 31 deletes the monitoring of the corresponding virtual network function after receiving the pre-condensed capacity notification.
Referring to fig. 5, fig. 5 is a flowchart illustrating a manual termination of a virtual network function according to a fifth embodiment of the present invention, where the fifth embodiment of the present invention is different from the fourth embodiment in the following steps:

Specifically, the termination process may be regarded as a full-scale capacity reduction process, the pre-capacity reduction notification includes identification information of at least one virtual network function, and the operation and maintenance module 31 deletes monitoring of the virtual network function corresponding to the identification information in the pre-capacity reduction notification after receiving the pre-capacity reduction notification.
A sixth embodiment of the present invention relates to a method for managing a virtual network function, where the sixth embodiment sends a performance acquisition request before a virtual network function management apparatus sends a pre-expansion notification or a pre-contraction notification, and determines sending of the pre-expansion notification or the pre-contraction notification according to an acquired performance value. It will be understood by those skilled in the art that the sixth embodiment of the present invention has the same or similar parts as the third or fourth embodiment, and the technical details already mentioned in the third or fourth embodiment are still valid in the sixth embodiment.
For the sake of brevity, the same steps or features as those of the third or fourth embodiment are not illustrated in the flowchart of the sixth embodiment.
