The virtual machine monitor 220 binds the second network card 231 of the virtual machine 230 to the virtual interface 213 of the network virtualized edge device 212 through the standard interface library 221.
Aiming at the problems that the network virtual edge equipment needs to be developed and adapted one by one to each manufacturer/version virtual machine monitor, the interface coupling degree between the virtual machine monitor and the network virtual edge equipment is high and the like at present, the application is realized by deploying the network virtual edge equipment and the required kernel and binary system/library on a server network card in a network card unloading mode and shielding private interfaces of the network virtual edge equipment of different manufacturers/versions through a standardized interface library. Compared with the original scheme, the method has the advantages that: 1. the network virtual edge equipment and the dependence thereof are deployed by using a network card unloading mode, so that the deployment efficiency of the software defined network is improved; 2. the network virtual edge device and the virtual machine monitor depend on different kernels and binary/libraries, so that the problem of environment-dependent conflict between the network virtual edge device and the virtual machine monitor is solved; 3. the virtual machine monitor calls the virtual interfaces of the standardized virtual machine virtual network card binding network virtual edge equipment, and the network virtual edge equipment of different manufacturers are subjected to unified adaptation, so that the service interfaces between the virtual machine monitor and the network virtual edge equipment are unified.
Referring now to fig. 3, fig. 3 is a block diagram of one embodiment of a network virtual service system of the present invention.
The network virtual service system includes a cloud computing platform 301, a virtual machine monitor manager 302, a software defined network controller 303, and a network virtualization server 300.
The network virtualization server 300 includes a first network card 310, a virtual machine 330 and its second network card 331, a virtual machine monitor 320 and its dependent second kernel, and a second executable software library 321.
The first network card 310 is deployed with a network virtualized edge device 312, a standard interface library 311 of the network virtualized edge device, a first kernel on which the network virtualized device 312 depends and a first executable software library 314, and a data path offload engine 315. The second network card 331 is a virtual network card. The virtual machine monitor 320 binds the second network card 331 of the virtual machine 330 to the virtual interface 313 of the network virtualized edge device 312 through the standard interface library 321.
Specifically, the first network card 310 may be, for example, an SOC (system on chip) type intelligent network card. The network virtualization edge device 312, the standard interface library 311 of the network virtualization edge device 312, and the first kernel and the first executable software library 314 on which the network virtualization device 312 depends are deployed in the ARM processor of the first network card 310.
Specifically, the network virtualized edge device 312 is an Open Virtual Switch (OVS) network virtualized edge device.
Specifically, the standard interface library 311 of the network virtualized edge device 312 includes a standardized interface 321A and an interface plug-in 321B. The standardized interface 321A is used to define the operation method and parameters of the standard interface library to bind and unbind the second network card of the virtual machine to the virtual interface of the network virtualized edge device. The interface plug-in 321B inherits the standardized interface to implement the conversion between the virtual interface and the standardized interface of the network virtualized edge device. Thus, the interface plug-in may be updated with the version update of the virtual interface of the network virtualized edge device without requiring changes to the virtual machine monitor 320.
Specifically, the standard interface library 311 is, for example, an os-vif standard interface library of OpenStack. OpenStack is an open-source cloud computing management platform project and is a combination of a series of software open-source projects. The os-vif standard interface in the os-vif standard interface library defines the operation method and parameters of the VM VNIC binding/unbinding NVE VPORT, the OVS provides an OVS plugin (321B) for inheriting the os-vif interface according to the os-vif standard interface library requirement, and the conversion from the standard interface to the OVS private interface is realized in the plugin.
Specifically, the data path offload engine 315 is configured to provide data path offload for the open virtual switching standard. Thereby facilitating binding and unbinding between interfaces.
Specifically, a second kernel on which the virtual machine monitor 320 depends and a second executable software library 321 are deployed in the virtual machine monitor 320. This eliminates the need to change the original virtual machine monitor 320.
Specifically, the first kernel and the second kernel may be, for example, linux operating system kernels, which is not limited in this disclosure, and kernels of other operating systems are also within the scope of the present disclosure. The executable software library may be, for example, a binary library for the user to invoke software, packages, or functions therein.
Specifically, the software defined network controller 303 is configured to issue control information to the network virtualized edge device 312. The control information may be at least one of a flow table and configuration information, for example. The configuration information may be, for example, to start or stop a certain port number in order to coordinate the creation or deletion process of the virtual machine. Thus, the network virtualized edge device 312 can process the network traffic of the virtual machine 330 corresponding to the network virtualized edge device 312 according to the control information issued by the first kernel and the first executable software library 314 of the dependent network virtualized edge device 312 and the software defined network controller 303.
Specifically, virtual machine monitor manager 302 is used to manage the network virtualization servers.
Further, the software defined network controller 303 and the virtual machine monitor manager 302 may be managed by the cloud computing platform 301 (e.g., openstack).
Thus, in the network virtualization service system provided by the application:
the NVE and the dependence (kernel, binary system/library) thereof are independently deployed by using a network card unloading mode, so that the deployment efficiency of SDN is improved, and the NVE and the Hypervisor depend on different kernels, binary systems/libraries, so that the problem of dependence on environment conflict of the NVE and the Hypervisor is solved; the Hypervisor calls the standardized VM VNIC to bind the NVE port interface, NVEs of different manufacturers provide plug in for unified adaptation, unification of service interfaces between the Hypervisor and the NVE is achieved, and version change of the NVE private interface only needs to update the corresponding plug in, so that the Hypervisor is not affected.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
