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. 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.
The embodiment of the invention is realized by expanding the NFV standard architecture. Before the embodiments of the present invention are described, a brief description of the NFV standard architecture is first given. Fig. 1 shows a schematic structural diagram of an NFV standard architecture, and as shown in fig. 1, the NFV standard architecture includes: OSS (Operation support system)/BSS (Business support system), EM (Entity Manager), VNF (virtualized Network Function), NFVI (Network Function virtualization Infrastructure), NFVO (Network Function virtualization editor), VNFM (virtualized Network Function Manager), and VIM (virtualized Infrastructure Manager).
The OSS/BSS is an original management system of an operator, and is configured to manage each network element in a network. Network elements in the network implement network function virtualization through EM, VNF, NFVI, NFVO, VNFM, and VIM.
Wherein, NFVI includes from the bottom layer upwards in proper order: physical Hardware resources (Hardware resources), virtualization Layer (virtualization Layer), and Virtual resources (Virtual resources). The physical Hardware resources may include a server (Computing Hardware), a Storage (Storage Hardware), and a Network appliance (Network Hardware); virtual resources may include Virtual Computing (Virtual Computing), Virtual Storage (Virtual Storage), and Virtual Network resources (Virtual Network).
The NFVI connects VNFs upward, and the VNFs run based on virtual resources included in the NFVI to implement corresponding network functions. There may be multiple VNFs, each VNF has a corresponding VNFD (VNF Descriptor, VNF template), and the VNFD includes all information of the VNF.
EM is used to manage VNF. There may be multiple EMs, and each VNF has a corresponding EM to manage the VNF.
The VNFM is used for managing the lifecycle of each VNF, including invoking the VIM and creating, maintaining, or terminating the VNF according to the VNFD; and monitoring the VNF, performing network element self-healing and capacity expansion and reduction on the VNF, and the like.
The VIM is respectively connected with the NFVI, the VNFM and the NFVO through message buses. The VIM is used for managing the NFVI, such as managing the authority of the NFVI, adding/recovering resources of VNF in the NFVI, analyzing the failure of the NFVI, collecting information of the NFVI, and the like. There may be multiple NFVIs under one NFV architecture, and each NFVI has a corresponding VIM for management, so the number of VIMs may be multiple.
The NFVO is connected with the VNFM and the VIM, and the NFVO is also connected with the OSS/BSS through a message bus, and is used for sending configuration information to the VNFM according to the information sent by the OSS/BSS so as to control the VNFM to manage the life cycle of the VNF, and sending the configuration information to the VIM so as to control the VIM to manage the NFVI. NFVO operates based on NSD (NS Descriptor) of NS (Network Service, not shown in the figure).
Currently, NFV gradually evolves toward a service-oriented direction, but a technology for introducing PaaS service into NFV does not appear yet, so that PaaS service cannot be provided to VNF in NFV. In order to solve the above problem, the present invention provides an instantiation method of a consumer VNF, so as to provide PaaS service to the consumer VNF in NFV.
The instantiation method of the VNF of the consumer is realized based on the NFV PaaS service architecture. Fig. 2 shows a schematic diagram of an NFV PaaS service architecture of a consumer VNF, which is provided in an embodiment of the present invention, and as shown in fig. 2, the NFV PaaS service architecture includes: customer VNF (corresponding to the customer VNF instance in fig. 2), VNFM, VIM, and PaaS service instances.
The PaaS service instance is uniformly modeled into a PaaS NFVI, and the PaaS NFVI is deployed in the NFVI. The PaaS NFVI and the VNF in the NFV can interact with each other in information and are deployed together with the NFVI. Meanwhile, a PaaS service management component is deployed in the VIM, and the VIM manages the PaaS service instance (namely, PaaS NFVI) through the PaaS service management component deployed in the VIM.
Specifically, the number of PaaS service instances may be one or more, the VIM may manage one or more PaaS service instances through the PaaS service management component deployed therein, and meanwhile, the VIM may instantiate a PaaS service through the PaaS service management component deployed therein to generate a PaaS service instance. The PaaS service instance provides a call interface to a consumer VNF (corresponding to the consumer VNF instance in fig. 2), so that the consumer VNF calls the corresponding PaaS service instance through the call interface to obtain the corresponding PaaS service. In a specific implementation, the interface may be an API interface or other interface capable of implementing a call function. Specifically, each PaaS service instance has a corresponding PaaS VNFD, and the PaaS VNFD includes all information of the corresponding PaaS service instance, such as an identifier, a type, and configuration information of the PaaS service instance. And the VIM manages the PaaS service instance according to the PaaS VNFD. The VNFM is respectively coupled with the VIM and the consumer VNF, the consumer VNF can call the PaaS VNFD from the VIM through the VNFM, and call the corresponding PaaS service instance according to the PaaS VNFD. In specific implementation, the customer VNF may call, from the VIM through the VNFM, an address of a PaaS service instance in the PaaS VNFD to call the corresponding PaaS service instance. Meanwhile, each consumer VNF has a corresponding consumer VNFD, which contains all information of the consumer VNF. The VNFM is used to manage the life cycle of the consumer VNF through the consumer VNFD, for example, call the VIM and create, maintain, or terminate the VNF according to the consumer VNFD; and monitoring the VNF, performing network element self-healing and capacity expansion and reduction on the VNF, and the like.
The management of the PaaS service instance by the VIM may include: service life cycle management, service directory management, service configuration management, service statistics and monitoring, service security and metering management, and the like. The service life cycle management can include query, registration, release, logout and the like of the PaaS service; the service directory management can comprise access list management of the PaaS service, calling of a full view of the configured PaaS service and the like; the service configuration management can include updating, writing, deleting and the like of configuration information of the PaaS service; the service statistics and monitoring may include statistics of information called by the PaaS service, monitoring execution of the PaaS service, and the like; the service security and metering management may include management of access rights to the PaaS service, management of information security of the PaaS service, auditing of the PaaS service, and so forth.
In a specific implementation, it is preferable to model the PaaS NFVI and the PaaS service management component based on a cloud native container technology, container and deploy the PaaS NFVI in the NFVI in a micro service architecture, and container and deploy the PaaS service management component in the VIM in a micro service architecture. The micro-service architecture has a light weight and can lead the deployment to be light, the micro-service architecture has the characteristic of independent expansion and deployment, and the coupling among all micro-services is loose coupling, so that the functional components in the micro-service architecture and the micro-service architectures can be flexibly combined and matched during the deployment; meanwhile, the micro service architectures are deployed based on the cloud native technology, centralized management of the micro service architectures can be achieved, resources of the micro service architectures are coordinated and distributed, and the reuse rate and the utilization rate of the resources are effectively improved.
Based on the NFV PaaS service architecture, as shown in fig. 3, the instantiation method of the consumer VNF provided by the present invention includes the following steps:
step S310: the VNFM receives an instantiation request of a consumer virtual network function VNF sent by the NFVO, wherein the instantiation request of the consumer VNF carries a consumer VNFD of the consumer VNF.
Specifically, the customer VNFD includes information related to the target PaaS service requested by the customer VNF, such as an ID of the target PaaS service, a name of the target PaaS service, and a type of the target PaaS service.
Step S320: and the VNFM determines a target PaaS service corresponding to the VNF of the consumer according to the VNFD of the consumer.
Specifically, the VNFM determines, according to the information related to the target PaaS service requested by the instantiation of the consumer VNF, the target PaaS service corresponding to the consumer VNF.
Step S330: the VNFM sends a service request message to a Virtual Infrastructure Manager (VIM); the service request message carries the identifier of the target PaaS service.
Step S340: and the VIM returns the PaaS service information of the PaaS service instance corresponding to the target PaaS service identifier to the VNFM.
The VIM determines a PaaS service instance corresponding to the target PaaS service identifier according to the PaaS VNFD and the target PaaS service identifier, acquires PaaS service information of the PaaS service instance corresponding to the target PaaS service identifier according to the PaaS VNFD of the PaaS service instance, returns the PaaS service information to the VNFM, and triggers the VNFM to instantiate the consumer VNF. And the consumer VNF acquires the PaaS service information from the VNFM, and is automatically connected with the PaaS service instance through a message bus according to the PaaS service information so as to call the PaaS service instance corresponding to the target PaaS service identifier and finish instantiation of the consumer VNF. In a specific implementation, the PaaS service information may be an access address of a PaaS service instance.
Therefore, in the instantiation method of the consumer VNF provided by the present invention, a PaaS service management component can be deployed in a VIM in an NFV, a PaaS service instance PaaS NFVI can be deployed in the NFVI, an instantiation request of the consumer VNF carrying a consumer VNFD of the consumer VNF is sent to a VNFM through an NFVO, the VNFM determines a target PaaS service corresponding to the consumer VNF according to the consumer VNFD, and sends a service request message carrying an identifier of the target PaaS service to the VIM, and the VIM acquires PaaS service information of the PaaS service instance corresponding to the identifier of the target PaaS service from the NFVI through the set PaaS service management component, so as to trigger the VNFM instantiation of the consumer VNF. And the customer VNF acquires the PaaS service information from the VNFM, and is automatically connected with the PaaS service instance through a message bus according to the PaaS service information so as to call the PaaS service instance corresponding to the target PaaS service identifier. The invention creates and deploys the PaaS service management component in the VIM based on the cloud native container technology, and deploys the PaaS service instance in the NVFI based on the cloud native container technology, so that the deployment tends to be light-weight, the deployment is more flexible, and the reuse rate and the utilization rate of resources can be effectively improved.
Figure 4 illustrates another method of instantiation of a consumer VNF as provided by the present invention. As shown in fig. 4, the method includes the steps of:
step S410: the VNFM receives an instantiation request of a consumer virtual network function VNF sent by the NFVO, wherein the instantiation request of the consumer VNF carries a consumer VNFD of the consumer VNF.
The execution process of this step is the same as step S310, and specifically refer to the corresponding description in step S310, which is not described herein again.
Step S420: and the VNFM determines a target PaaS service corresponding to the VNF of the consumer according to the VNFD of the consumer.
Step S430: the VNFM sends a service request message to the virtual infrastructure manager VIM.
Wherein, the service request message at least carries: identification of the target PaaS service and type of the target PaaS service. The types of the target PaaS service include: public PaaS services and private PaaS services. The public PaaS service is a PaaS service provided for all the VNFs of the consumers, such as a load balancing service, a security detection service, a database service, or the like; the dedicated PaaS service is a PaaS service provided to a VNF of a specified consumer, for example, a Web service.
Step S440: the VIM judges whether the PaaS service corresponding to the identification of the target PaaS service is a special PaaS service or not; if the determination result is negative, executing step S450; if yes, go to step S470.
Specifically, whether the PaaS service corresponding to the identifier of the target PaaS service is the dedicated PaaS service is determined according to the type of the target PaaS service included in the service request message.
If the PaaS service corresponding to the identifier of the target PaaS service is not the dedicated PaaS service, that is, the PaaS service corresponding to the identifier of the target PaaS service is the public PaaS service, executing step S450; if the PaaS service corresponding to the target PaaS service identifier is the special PaaS service, executing step S460;
here, it should be noted that this step is an optional step, and when this step is not executed, step S450 may be executed directly after step S430 is executed.
Step S450: the VIM determines whether the PaaS service corresponding to the target PaaS service identifier is not instantiated, if yes, step S460 is executed, and if no, step S470 is executed.
Specifically, in the case of executing step S440, if the PaaS service corresponding to the identifier of the target PaaS service is a public PaaS service, in this step, the VIM may search, according to the identifier of the target PaaS service carried in the service request message, whether a PaaS service instance of the public PaaS service corresponding to the identifier of the target PaaS service exists in the local database, and if so, it indicates that the PaaS service corresponding to the identifier of the target PaaS service is instantiated, and then step S470 is executed;
if the target PaaS service does not exist, the fact that the PaaS service instance of the public PaaS service corresponding to the identifier of the target PaaS service is not contained in the local service management component is shown, the service request message is sent to the service registration database in one step to request the PaaS service instance of the public PaaS service from the service registration database, the service request feedback message fed back by the service registration database is received, and whether the PaaS service corresponding to the identifier of the target PaaS service is not instantiated or not is judged according to the service request feedback message.
In specific implementation, whether the service request feedback message contains PaaS service information of a PaaS service instance corresponding to the target PaaS service identifier can be judged; if not, it indicates that the PaaS service corresponding to the target PaaS service identifier is not instantiated, and then step S460 is executed; if yes, it indicates that the PaaS service corresponding to the identifier of the target PaaS service is instantiated, and step S470 is executed.
Of course, it may be understood that, without performing step S440, the VIM may also directly search whether PaaS service information of a PaaS service instance corresponding to the identifier of the target PaaS service exists in the local service management component, or send a service request message to the service registration database, and search whether PaaS service information of a PaaS service instance corresponding to the identifier of the target PaaS service exists in the service registration database, if not, it indicates that the PaaS service corresponding to the identifier of the target PaaS service is not instantiated, then step S460 is performed, otherwise, step S470 is performed.
Step S460: and the VIM instantiates the PaaS service corresponding to the target PaaS service identifier.
Step S470: and the VIM returns the PaaS service information of the PaaS service instance corresponding to the target PaaS service identifier to the VNFM.
Specifically, the VIM acquires PaaS service information of a PaaS service instance corresponding to the target PaaS service identifier from the PSD corresponding to the target PaaS service according to the target PaaS service identifier, and returns the PaaS service information to the VNFM to trigger the VNFM to instantiate the consumer VNF.
