All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The use of the terms first, second, etc. do not denote any order, and the terms first, second, etc. may be interpreted as names of the objects described. In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion. Further, in the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
Before describing the embodiments of the present invention, a brief description will be given to the current way of creating (i.e., instantiating) a virtualized forwarding plane network element. At present, the creation of a virtualized forwarding plane network element is implemented based on the NFV architecture defined by ETSI. The architecture diagram of the NFV architecture is shown in fig. 1, and includes: NFVO (Network Function virtualization editor), VNFM (virtual Network Function Manager), VNF (virtual Network Function), VIM (virtualization Infrastructure Manager), and middleware layer (Hypervisor). The NFVO is used for realizing functions of VNF deployment template management, VNFM completion VNF life cycle management and the like; the VNFM is used for realizing functions of VNF life cycle management, VNF instance creation, deletion and the like; the VIM is used for controlling and managing an intermediate software layer to control and manage virtual resources in a virtualized resource pool, such as creating, deleting and the like on the virtual machine; the VNF is a virtualized mobile core network element, and in particular, in order to reduce the service transmission delay, the VNF is usually deployed by using a control forwarding separation architecture, that is, the VNF is divided into a control plane and a forwarding plane, the control plane and the forwarding plane of the VNF respectively correspond to S (Session Management Function)/PGW (PDN GateWay, PDN (Packet data network) GateWay) -C and S/PGW-U shown in fig. 1, the S/PGW-C is a control plane network element for implementing control plane functions such as user mobility Management and Session Management, the deployment position of the S/PGW-U is relatively closer to the user, therefore, the data transmission distance can be effectively shortened by forwarding the data through the S/PGW-U so as to reduce the data transmission delay, and the S/PGW-U is a virtualized forwarding plane network element for realizing the functions of forwarding planes such as user data message forwarding and the like.
Currently, the process of instantiating a virtualized forwarding plane network element is the same as the process of instantiating a VNF, that is, before instantiating a VNF, a manually deployed VNF deployment template needs to be manually imported on a NFVO, where the VNF deployment template includes VNF configuration parameters required for creating a VNF, such as a VNF capacity size, a VNF name, and a VNF type; then, selecting a virtualized resource pool for the VNF in a manual selection mode to deploy the VNF based on the virtualized resources in the virtualized resource pool; when the VNF is instantiated, an operator needs to manually trigger a VNF instantiation request including the VNF deployment template on the NFVO, so that the NFVO sends the VNF instantiation request to the VNFM, and the VNFM makes the VNFM request virtual resources to the VIM and the intermediate software layer according to the sampling information in the VNF instantiation request to instantiate the VNF.
Based on the process of instantiating the VNF, it can be known that currently, instantiating the virtualized forwarding plane network element still needs to be implemented in a manual deployment manner, which results in low deployment efficiency and deployment accuracy of the virtualized forwarding plane network element and complex deployment process.
In order to solve the above problem, an embodiment of the present invention provides a method for creating a virtualized forwarding plane network element, which is shown in fig. 2 and includes the following steps:
step S210: and acquiring pre-configured network location service area information and user information of a user in a network element of the virtualization control plane every a preset period.
Specifically, the network service area configuration information may be information such as an area coverage of the network service area planned during network construction, for example, a coverage of the network service area TA and a coverage of the network service area EC. In specific implementation, the coverage area of the network service area TA is preferably used as the network service area configuration information in the embodiment of the present invention. The user information of the user in the virtualized control plane network element, that is, the information related to the user in the virtualized control plane network element, may include a user identifier of the user in the virtualized control plane network element, a user access position of the user, and the like; wherein, the user access location is the user access network location service area. Of course, it is understood that the above listed user information is only exemplary, and in particular implementation, the user information of the user in the virtualization control plane network element includes, but is not limited to, the above listed information, and the user information is only related to the user.
In specific implementation, the user information of the user in the network element of the virtualization control plane may dynamically change according to the actual situation of the user and the actual use situation of the user on the network. For example, the geographical location of the user accessing the network may change at any time, and the user may change the subscription type of the user according to the actual situation. Therefore, in the embodiment of the invention, the user information acquired every preset period is the user information which is real-time and dynamically changed. The preset period can be set by those skilled in the art according to practical situations, and the present invention is not limited thereto.
Step S220: and acquiring sampling information of each network location service area according to the network location service area information and the user information.
The sampling information at least includes: the maximum user number, the target system capacity and the virtual resource pool information corresponding to the network location service area of each network location service area in a preset period.
The number of users in each network location service area and the system capacity are obtained at preset intervals, and the system capacity is changed in real time and dynamically, so that the sampling information can be obtained in the following manner: firstly, counting the real-time user number and real-time system capacity (the size of storage space occupied by data in the system) of each network location service area in a preset period in real time; and then acquiring the maximum user number and the target system capacity according to the counted real-time user number and the real-time system capacity. The maximum user number is the maximum value of the real-time user numbers counted in a preset period; the target system capacity may specifically be: the maximum value of the real-time system capacity counted in the preset period, or the average value of the real-time system capacity counted in the preset period, or a corresponding value obtained after calculating the real-time system capacity counted in the preset period by using a preset algorithm, and the like. The preset algorithm may be set by a person skilled in the art according to actual situations, and the present invention is not limited to this.
The virtual resource pool information corresponding to the network location service area may be determined according to the user access location of the user in the user information. Specifically, the user access position carries an identifier of a network location service area to which the user accesses, and in this step, a corresponding relationship table between the user access position and the virtual resource pool may be preset, a target virtual resource pool corresponding to the user access position is determined, then a virtual resource pool identifier of the target virtual resource pool is obtained, and the virtual resource pool identifier is used as virtual resource pool information corresponding to the user. In the correspondence table, each user access position corresponds to a virtual resource pool closest to the user access position in the geographic position. In a specific implementation, the virtual resource pool identifier may specifically be: an ID of the virtual resource pool, and so on. Because the virtualized forwarding plane network element is deployed based on the virtualized resources in the virtualized resource pool, when the virtualized forwarding plane network element is created, a corresponding virtual resource pool needs to be selected for users in each network location service area. In addition, the virtual resource pool matched with the user access position can be automatically determined according to the corresponding relation table of the user access position and the virtual resource pool, and the working complexity of operation and maintenance personnel is greatly reduced.
Step S230: judging whether the sampling information meets a preset condition or not; if yes, go to step S240; if the determination result is negative, step S220 is executed again.
The preset condition may be various, for example, the maximum number of users is greater than or equal to a preset threshold number of users, or the target system capacity exceeds a preset threshold, and so on. In a specific implementation, the preset condition may be set by a person skilled in the art according to an actual situation, and the present invention is not limited thereto.
In this step, preferably, the preset condition may be: if the maximum number of users is greater than or equal to the preset threshold value of the number of users, the execution process of this step may specifically be: judging whether the maximum user number is greater than or equal to a preset user number threshold value or not; if yes, go to step S240; if the determination result is negative, step S220 is executed again. The preset user number threshold may be set by a person skilled in the art according to actual situations, and the present invention is not limited thereto.
Step S240: and sending the sampling information to the NFVO so that the NFVO can instantiate a virtual forwarding plane network element according to the sampling information.
Specifically, the sampling information including the maximum number of users in each network location service area in a preset period, the target system capacity, and the virtual resource pool information corresponding to the users in each network location service area is sent to the NFVO, so that the NFVO instantiates the virtualized forwarding plane network element according to the sampling information. The NFVO determines the deployment position of the network element of the virtualized forwarding plane according to the virtual resource pool information corresponding to the network location service area, for example, a corresponding position may be selected as the deployment position of the network element of the virtualized forwarding plane within a preset area range close to the virtual resource pool position corresponding to the virtual resource pool information. The selection manner of the preset area range and the corresponding position may be set by a person skilled in the art according to circumstances, and the present invention is not limited thereto. And the NFVO instantiates the system capacity of the network element of the virtual forwarding plane according to the sampling information, namely the target system capacity. In specific implementation, the NFVO may send the instantiation request of the network element of the virtualized forwarding plane carrying the sampling information to the VNFM, so that the VNFM requests the VIM and the intermediate software layer for virtual resources according to the sampling information to instantiate the network element of the virtualized forwarding plane.
Therefore, the invention can dynamically acquire the network location service area information in each network location service area and the user information of the user in the virtualized control plane network element, automatically configure the more accurate deployment information of the virtualized forwarding plane network element and automatically trigger the instantiation process of the virtualized forwarding plane network element by processing the network location service area information and the user information, reduce the work complexity of operation and maintenance personnel, effectively avoid the larger deployment information planning deviation when manually configuring the deployment information, effectively avoid the problems of too low resource utilization rate or too high system load caused by the larger deployment information planning deviation when manually configuring the deployment information, and improve the deployment efficiency and the deployment precision of the virtualized forwarding plane network element.
Based on the foregoing solution, preferably, an embodiment of the present invention further provides another method for creating a virtualized forwarding plane network element, which is shown in fig. 3, and the method includes the following steps:
step S310: and acquiring pre-configured network location service area information and user information of a user in a network element of the virtualization control plane every a preset period.
Specifically, the execution process of this step may specifically refer to the corresponding description in step S210, and the difference between this step and step S210 is: in this step, the user information may further include: a user rating. The user level is a subscription level of the user, such as a high-level user who has subscribed to a high-level protocol, a normal user who has subscribed to a normal protocol, and so on. In the embodiment of the present invention, the preferred user classes include: advanced users, and general users. Of course, it is understood that in this embodiment, the user level may be multiple, and the present invention is not limited thereto.
Step S320: and respectively acquiring sampling information corresponding to each user grade in each network location service area in a preset period according to the network location service area information and the user information.
For example, in the embodiment of the present invention, if the user rank may include: in this step, the advanced user and the general user respectively obtain the sampling information of the advanced user and the sampling information of the general user in each network location service area within a preset period. The sampling information corresponding to each user level is obtained in the same manner as the sampling information obtained in step S220, and reference may be specifically made to the corresponding description of obtaining the sampling information in step S220, which is not described herein again.
Step S330: and respectively judging whether the sampling information corresponding to each user grade meets the user grade preset conditions corresponding to each user grade.
The user level preset condition may be set by a person skilled in the art according to an actual situation, which is not limited in the present invention. In specific implementation, the user level preset condition may preferably be: the maximum user number corresponding to the user level is larger than or equal to a preset user number threshold of the user level. In this step, if it is determined that the sampling information corresponding to the user level meets the user level preset condition corresponding to the user level, step S340 is executed; otherwise, step S320 is executed again.
For example, the user level is a premium user, the preset user number threshold of the premium user is 5000, if the obtained maximum user number of the premium user is 6000, and at this time, the maximum user number corresponding to the premium user is greater than the preset user number threshold of the premium user, it is determined that the sampling information corresponding to the premium user meets the user level preset condition corresponding to the premium user, then step S340 is executed; if the obtained maximum number of the premium users is 4500, and at this time, the maximum number of the users corresponding to the premium users is smaller than the preset user number threshold of the premium users, it indicates that the sampling information corresponding to the premium users does not meet the user level preset condition corresponding to the premium users, and step S320 is executed again. When the user level is a normal user, the determination manner for the normal user is similar to the determination manner for the advanced user, and reference may be specifically made to the description of the determination manner for the advanced user, which is not described herein again.
Step S340: and sending the sampling information corresponding to the user grade meeting the user grade preset condition to the NFVO so that the NFVO can instantiate the network element of the virtual forwarding plane according to the sampling information corresponding to the user grade meeting the user grade preset condition.
And for the user grade meeting the user grade preset condition, sending the sampling information corresponding to the user grade to the virtualization control plane network element so that the virtualization control plane network element instantiates the virtualization forwarding plane network element according to the sampling information corresponding to the user grade meeting the user grade preset condition. The system capacity of the virtualized forwarding plane network element created by the virtualized control plane network element according to the sampling information corresponding to the user level is the target system capacity in the sampling information corresponding to the user level, and the deployment position of the virtualized forwarding plane network element is determined according to the virtual resource pool information corresponding to the network location service area in the sampling information corresponding to the user level. For example, a corresponding position may be selected as a deployment position of the virtualized forwarding plane network element within a preset area range near the virtual resource pool position corresponding to the virtual resource pool information. The selection manner of the preset area range and the corresponding position may be set by a person skilled in the art according to circumstances, and the present invention is not limited thereto.
Through steps S310 to S340, a virtualized forwarding plane network element corresponding to the user class can be created for different user classes in combination with the user classes, so as to ensure that services dedicated to the user classes are provided for different user classes, for example, a virtualized forwarding plane network element dedicated to a premium user can be created for the premium user, and a premium service dedicated to the premium user is provided for the premium user through the virtualized forwarding plane network element dedicated to the premium user, so as to ensure the service experience of the premium user.
The present invention further provides a device for creating a virtualized forwarding plane network element, as shown in fig. 4, including:
