Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present application, are given by way of illustration and explanation only, and are not intended to limit the present application.
It should be noted that the terms "first" and "second" in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Referring to fig. 2, a schematic diagram of an architecture of a container-based virtual resource management system according to an embodiment of the present application is provided.
As shown, the container-based virtual resource management System 200 (only the portion related to the embodiment of the present application is shown in the figure) is composed of a Network Function Virtualization Orchestrator (NFVO), a Virtualized Network Function Manager (VNFM), a container manager (container controller), and a Virtualized Infrastructure Manager (VIM), and provides overall management and orchestration of the container-based NFV, and accesses an Operation Support System (OSS/BSS) upwards.
The NFVO is used to coordinate management of a VNF lifecycle (which needs to be supported by a VNFM), coordinate management of various resources (which needs to be supported by a VIM) of a Network Function Virtualization Infrastructure (NFVI), and coordinate allocation and authorization of virtual resources for the VNF according to a usage of the virtual resources in the virtual resource pool, so that optimized configuration of various resources and connections is ensured under reasonable arrangement of each VNF and the virtual resources.
The NFVM is configured to manage life cycles of VNFs and container-based VNFs, such as online, offline, and performing status monitoring, and the NFVM may determine, according to a create VFN request initiated by the NFVO, whether the VNF requested to be created is a traditional VNF or a container-based VNF, for example, if the number of available virtual resources of a container managed by the container manager is smaller than the number of virtual resources required to create the VNF, that is, the status of the container manager is unavailable, the NFVM determines that the create VFN request initiated by the NFVO is to create the traditional VNF, and if the status of the container manager is available, the NFVM determines that the create VFN request initiated by the NFVO is to create the container-based VNF.
The container manager is used for managing a VM created by the VIM according to indication information of virtual resources authorized by the NFVO as a node through information interaction with the NFVO and the VIM, creating a required container for a VNF applying for creation, detecting the number of available nodes, determining the state of the container manager, and notifying the VNFM of the state, wherein the node is used for deploying a container for bearing VNF services.
The VIM is used to manage NFVI and control virtual resource allocation of VNFs, such as virtual computing, virtual storage, and virtual networking. The VIM may request for the VM needed to create the VNF through information interaction with the container manager.
Based on the system architecture shown in fig. 2, an embodiment of the present application provides a virtual resource management method based on a container, where the method is used to implement application and authorization of virtual resources.
Fig. 3 is a schematic message interaction diagram of container-based virtual resource authorization according to an embodiment of the present application. The process is used for describing the process of realizing the application and authorization of the virtual resources when the number of the available virtual resources allocated to the managed container by the container manager is lower than or equal to a set threshold value.
As shown, the process includes:
s301: the container manager detects the amount of available virtual resources that can be allocated for management.
Specifically, the container manager detects the total load condition of available nodes in a node (node) resource pool managed by the container manager in real time and the number of remaining allocable nodes; the node is an available virtual resource which can be allocated to a managed container in a container manager and is used for deploying a container for bearing VNF service, one node corresponds to one VM, and a plurality of containers can be configured in one node; virtual resources are created by the VIM that provide infrastructure services for the VNF, such as virtual CPUs, virtual memory, etc.
S302: the container manager sends a first notification message to the VNFM for notifying the container manager that the status is unavailable.
In S302, when the container manager detects that the number of remaining allocatable nodes is lower than or equal to the set threshold, the container manager sends a first notification message for notifying that the state of the container manager is unavailable to the VNFM, and sets the state of the container manager as unavailable, that is, the container-based VNF cannot be created.
The set threshold may be preset based on an upper limit of the total load in the node resource pool managed by the container manager. Specifically, the set threshold may be an absolute value of the number of virtual resources, such as the number of virtual CPUs is less than 20, and/or the number of virtual memories is less than 500G; may be a relative value of the virtual resources, such as the number of virtual CPUs is less than 10% of the total number of the virtual resource pool, and/or the virtual memory is less than 10% of the total number of the resource pool, etc.; or a combination of a plurality of thresholds, for example, the number of virtual CPUs is less than 10% of the total number of the virtual resource pools, and the virtual memory is less than 500G.
S303: the container manager sends a virtual resource application request message to the NFVO.
Once the container manager detects that the number of nodes managed by the container manager is lower than or equal to a set threshold, a virtual resource application request message for applying for a virtual resource is sent to the NFVO, so as to ensure that the nodes managed by the container manager can configure a container carrying the VNF.
S304: and after receiving the virtual resource application request message, the NFVO allocates the virtual resources to the container manager according to the use condition of the virtual resources in the virtual resource pool.
S305: and the NFVO carries the indication information of the virtual resources authorized to the container manager in a virtual resource application confirmation message and sends the indication information to the container manager.
The indication information of the virtual resource is used to specifically describe the virtual resource authorized by the NFVO to the container manager, for example, the indication information of the virtual resource includes information about the number of VMs, information about the size of each VM, and identification information and number information of a virtual CPU authorized to the container manager and identification information and size information of a virtual memory authorized to the container manager, which are included in each VM.
S306: and the container manager receives the virtual resource application confirmation message, carries the indication information of the authorized virtual resources in the VM creation request message and sends the VM creation request message to the VIM.
S307: the VIM receives the VM creating request message, creates a VM for the container manager according to the indication information of the authorized virtual resources carried in the VM creating request message, and sends a VM creating confirmation message to the container manager, wherein the VM creating confirmation message carries the indication information of the VM created for the container manager.
The VM indication information includes VM identification information and VM configuration information, for example, the VIM creates the VM1 and the VM2 for the container manager according to the authorized virtual resource indication information, and sends the VM creation confirmation message to the container manager by carrying the VM1 and the VM2 identification information and the configuration information such as the number of containers that can be configured respectively based on the VM1 and the VM 2.
S308: the container manager receives the VM creation confirmation message and manages the created VM as a node.
S309: the container manager sends a second notification message to the VNFM for notifying the container manager that the status is available.
And the container manager detects that the number of the remaining allocatable nodes is higher than a set threshold, sends a second notification message for notifying that the state of the container official gas is available to the VNFM, and sets the state of the container manager as available, namely the container manager can receive a container creation request message sent by the VNFM, and further complete the creation of the VNF based on the container.
Based on the flow shown in fig. 3, fig. 4 is a schematic diagram of message interaction created by the container-based VNF according to the embodiment of the present application.
As shown, the process includes:
s401: the NFVO sends a create VNF request message to the VNFM.
The VNF creation request message carries indication information of virtual resources required for creating the VNF, and the description information of the virtual resources includes information on the number of VMs required for creating the VNF, size information of each VM, identification information and number information of a virtual CPU and a virtual memory authorized to the container manager, which are included in each VM, and identification information and size information of a virtual memory authorized to the container manager.
S402: the VNFM detects a status of the container manager according to the received create VNF request message.
Wherein the state of the container manager includes a container management state available and a container management state unavailable. If the number of the remaining nodes managed by the container manager is higher than the set threshold, the container management state is available, and the VNF based on the container can be created; otherwise, the state of container management is not available, i.e. no container-based VNF can be created.
S403: and the VNFM sends a container creating request message to the container manager, wherein the container creating request message carries indication information of the virtual resources required by the VNF.
S404: the container manager creates a container for the VNF based on the hosted available node resources according to the received create container request message, and sends a container create confirm message to the VNFM.
S405: the VNFM receives the container creation acknowledgement message sent by the container manager and sends the VNF creation acknowledgement message to the NFVO.
Optionally, if the VNFM detects that the status of the container manager is unavailable in S402, the VNFM sends a VNF creation failure message to the NFVO; the VNFM may determine whether to create a legacy VNF or to create a container-based VNF waiting for detection of the container manager's state to be available, depending on the specific functionality implemented by the VNF.
In the above embodiment of the present application, first, the container manager detects the number of available virtual resources allocated to the managed container by the container manager, and when detecting that the number of available virtual resources is lower than or equal to a set threshold, sends a first notification message for notifying that the state of the container manager is unavailable to the VNFM, and sends a virtual resource application request message to the NFVO, and sends a create VM request message to the VIM according to indication information of authorized virtual resources returned by the NFVO, and the container manager uses a VM created by the VIM as an available virtual resource that can be allocated to the managed container in the container manager, and sends a second notification message for notifying that the state of the container manager is available to the VNFM, thereby completing the process of applying for and authorizing virtual resources.
The container manager detects the number of available virtual resources allocated to the managed container in real time, and once the number of available virtual resources is detected to be lower than or equal to a set threshold, sends a status notification message to the VNFM and completes application and authorization of the virtual resources through information interaction with the NFVO and the VIM, that is, the number of available virtual resources allocated to the managed container is increased, and the container manager is available in status, so that a container required by the VNF can be created for a VNF applied for creation by the NFVO. Since the instantiation time of the container-based VNF includes the application authorization time of the virtual resource and the starting time of the container, the VNF creation process is decoupled from the application authorization process of the virtual resource, the virtual resource allocation and the virtual resource authorization are not required in the VNF creation process, and only the container-based VNF is created, thereby shortening the instantiation time of the container-based VNF and realizing the creation of the container-based VNF.
