With the introduction of SDN and computing virtualization, there are multiple SDN and computing virtualization technologies of different vendors for a cloud resource pool. When events such as new establishment occur in the virtual machine, the SDN needs to sense the virtualization events, update corresponding network configuration, direct the flow of the virtual machine, and ensure normal operation of network functions.

The internal interface of the computing virtualization relates to factory secrets, and the cooperation can be realized only between the SDN and the computing virtualization factory, which are the same factory or deeply cooperated. Moreover, interfaces of different computing virtualization manufacturers are different and cannot be reused, and the SDN controller needs to be adapted to different manufacturers one by one, so that the cooperation difficulty is high.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
The present disclosure is directed to enabling decoupling and coordination of SDN controllers and virtualization management nodes. When events related to virtualization life cycles such as new building, starting, shutdown, deletion, migration, network card addition/deletion and the like occur to the virtual machine, a corresponding mechanism is provided to make the SDN controller aware of the virtualization events. After the Virtualization events are sensed, the SDN can update the Network configuration of the corresponding NVE (Network Virtualization Edge) node, so as to guide the virtual machine and ensure that the Network function works normally.
Fig. 1 is a schematic diagram of a network deployment and implementation process of decoupling and coordination of an SDN controller and a virtualization management node according to the present disclosure.
As shown in fig. 1, decoupling and coordination of the SDN controller and the virtualization management node are implemented by using a virtual machine event processing device. The virtual machine event processing device (which can be a cloud management device) adds a virtualization event processing module to expose a corresponding callable event interface and provides a virtualization event subscription mechanism. And the SDN controller updates the network configuration after subscribing to the corresponding virtualization event through a virtualization event subscription mechanism.
As shown in fig. 1, a vSwitch (Virtual Switch), an SDN gateway, a Hypervisor (Virtual machine monitor), an NVE node, a VM (Virtual machine) and the like are also set in the network. The vSwitch works in a two-layer data network, and realizes the two-layer (and partial three-layer) network function of the physical switch in a software mode. Hypervisors, also known as Virtual Machine Monitors (VMMs), are software, firmware, or hardware running between underlying physical servers and operating systems to build and execute virtual machines. Computers that are used by hypervisors to execute one or more virtual machines are called host machines (guest machines), and these virtual machines are called guest machines (guest machines). The hypervisor provides a virtual operating platform to execute a guest operating system (guest operating systems) and is responsible for managing the execution phases of other guest operating systems; the guest operating systems share the virtualized hardware resources.
As shown in fig. 1, a virtual machine event processing method based on decoupling and coordination of an SDN controller and a virtualization management node includes: steps S11-S16.
In step S11, the user (or tenant) initiates a virtual machine lifecycle related request through the virtual machine event processing apparatus (or cloud management apparatus).
The related requests of the life cycle of the virtual machine comprise requests of newly building, starting up, shutting down, deleting, migrating, adding or deleting a network card and the like of the virtual machine.
Step S12, in response to the virtual machine lifecycle related request initiated by the user, the virtual machine event processing apparatus sends the virtual machine lifecycle related request to the virtualization management node.
Step S13, the virtualization management node executes the virtual machine lifecycle related operation corresponding to the virtual machine lifecycle related request.
The related operation of the life cycle of the virtual machine comprises the operations of newly building, starting up, shutting down, deleting, migrating, adding or deleting the network card and the like of the corresponding virtual machine.
And step S14, the virtualization management node calls an event interface of the virtualization event processing module and reports the relevant operation information of the life cycle of the virtual machine.
The event interface is exposed to the virtualization management node such that the virtualization management node accesses the virtualization event management module through the event interface.
The virtual machine life cycle related operation information comprises a virtual machine life cycle related operation result and corresponding parameter information.
Step S15, based on the event subscription mechanism of the virtualization event processing module, the virtual machine event processing device sends the relevant operation information of the virtual machine life cycle as subscription information to the SDN controller, and the SDN controller obtains the relevant operation information of the subscribed virtual machine life cycle.
And step S16, the SDN controller updates the corresponding network configuration according to the relevant operation information of the virtual machine life cycle.
The updated network configuration includes respective flow table configurations of the NVE and SDN gateways.
In the above embodiment, the decoupling and the cooperation between the SDN controller and the virtualization management node are realized through the virtualization event processing module, the exposed event interface thereof, and the corresponding virtualization event subscription mechanism. The event interface provides code-level enterprise standards, and each virtualization management node manufacturer can work normally by being matched with the event interface of the virtual machine event processing device at one time, so that the embarrassment that different manufacturers are matched one by one is eliminated. The internal interface of the virtualization management node does not need to be exposed, the business concealment and integrity of the virtualization management node are guaranteed, and the factory acceptance degree is high. The SDN controller and the virtualization management nodes are fully decoupled, vertical shafts and locking of manufacturers are avoided, the SDN controller is not required to be adapted to the virtualization management nodes of different manufacturers one by one, cooperation difficulty is low, meanwhile, the SDN controller and the virtualization management nodes of different manufacturers can be selected according to requirements to formulate a solution, and products of various industries and benefits brought by competition are utilized to the maximum degree.
The decoupling and cooperative docking of the SDN controller of the manufacturer 1 and the virtualization management node of the manufacturer 2 are taken as an example to explain the processing process of the newly-built virtual machine.
As shown in fig. 2, a new virtual machine processing process implemented by decoupling and cooperating an SDN controller of a manufacturer 1 and a virtualization management node of a manufacturer 2 includes: steps S21-S26.
In step S21, the user (or tenant) initiates a request for new virtual machine through the virtual machine event processing apparatus (or cloud management apparatus).
In step S22, in response to the request for creating a new virtual machine initiated by the user, the virtual machine event processing apparatus sends the request for creating a new virtual machine to the virtualization management node of the manufacturer 2.
Step S23, the virtualization management node of the manufacturer 2 picks out a suitable computing node, and initiates the invocation of the new virtual machine.
Step S24, the virtualization management node of the manufacturer 2 calls the event interface of the virtualization event processing module, reports the virtual machine creation event, and carries parameter information such as the network card of the virtual machine, the host name of the virtual machine, and the like.
Step S25, based on the event subscription mechanism of the virtualization event processing module, the virtual machine event processing device sends the virtual machine creation event and the related parameter information as subscription information to the SDN controller of the manufacturer 1, and the SDN controller of the manufacturer 1 subscribes to the virtual machine creation event to obtain parameter information such as the network card of the virtual machine and the host name to which the virtual machine belongs.
Step S26, the SDN controller of the manufacturer 1 finds a correct NVE according to the host information, correctly inserts the network card into the relevant interface on the NVE according to the virtual machine network card information, and configures the NVE and the flow table on the SDN gateway as the virtual machine flow guide.
Therefore, the virtual machine new building process is realized based on the decoupling and cooperation of the SDN controller of the manufacturer 1 and the virtualization management node of the manufacturer 2.
