In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
Fig. 1 is a flowchart illustrating a virtual data center networking method in a heterogeneous environment according to an embodiment of the present invention. The large two-layer network interworking architecture in the heterogeneous environment is mainly implemented by a service management platform, an SDN controller, a cloud management platform, and a VTEP (VXLAN Tunnel End Point, VXLAN Tunnel terminal) provided by a network device.
In step 110, the cloud management platform creates a Virtual machine, and creates a VLAN (Virtual Local Area Network) to which the Virtual machine belongs on an OVS (Open Vswitch).
At step 120, the SDN controller creates a VLAN on the first physical switch to which the physical machine belongs. The VLAN IDs (identifications) of the physical machine and the virtual machine may be different.
In step 130, the service management platform issues the interworking requirements of the virtual machine and the physical machine to the cloud management platform and the SDN controller, so that the cloud management platform and the SDN controller interact with the first key information. The first key information includes the VLAN number to which the virtual machine belongs, and information of the attached physical switch. Wherein the physical switch is used to implement VTEP functionality. In one embodiment, the SDN controller may obtain, through the EVPN protocol, a VLAN identifier to which the virtual machine belongs and VTEP location information where the virtual machine belongs.
In step 140, the SDN controller issues second critical information to a first physical switch attached to the physical machine and a second physical switch attached to the virtual machine according to the first critical information. The second key information is, for example, a mapping relationship between a VLAN and a VNI. For example, the SDN controller issues, to a first physical switch attached to a physical machine, a first mapping relationship of a first VNI between a VLAN to which the physical machine belongs and the first physical switch, and issues, to a second physical switch attached to a virtual machine, a second mapping relationship of a second VNI between the VLAN to which the virtual machine belongs and the second physical switch. Wherein, the first VNI and the second VNI may be the same or different.
In step 150, the first physical switch and the second physical switch implement data exchange between the physical machine and the virtual machine according to the second key information. For example, when data sent by the virtual machine arrives at the second physical switch, the carried VLAN is converted into the corresponding VNI by the second physical switch according to the second mapping relationship, and when the encapsulated data packet arrives at the first physical switch, the first physical switch converts the VNI into the corresponding VLAN according to the first mapping relationship.
In this embodiment, the SDN server issues the second key information to each physical switch, so that the physical switch attached to the virtual machine and the physical switch attached to the physical machine realize data exchange between the physical machine and the virtual machine according to the second key information, thereby realizing flexible intercommunication between the virtual machine and the physical machine.
Fig. 2 is a flowchart illustrating a virtual data center networking method in a heterogeneous environment according to another embodiment of the present invention.
In step 210, the cloud management platform creates a virtual machine and creates a VLAN on the OVS to which the virtual machine belongs. The virtual switch where the virtual machine is located isolates the tenant through the VLAN, and the VLAN is transmitted to the physical switch which is connected with the virtual machine.
At step 220, the SDN controller creates a VLAN on the first physical switch to which the physical machine belongs. The VLAN IDs of the physical machine and the virtual machine may be different.
In step 230, the service management platform issues the interworking requirement of the virtual machine and the physical machine to the cloud management platform and the SDN controller, respectively.
In step 240, the cloud management platform sends the VLAN identifier to which the virtual machine belongs and the VTEP location information where the virtual machine belongs to the SDN controller, that is, the cloud management platform sends the location information of the second physical switch to the SDN controller. The first physical switch realizes the function of the VTEP where the physical machine is located, and the second physical switch realizes the function of the VTEP where the virtual machine is located.
In step 250, the SDN controller issues, to a first physical switch attached to the physical machine, a first mapping relationship of a first VNI between the VLAN to which the physical machine belongs and the first physical switch, and issues, to a second physical switch attached to the virtual machine, a second mapping relationship of a second VNI between the VLAN to which the virtual machine belongs and the second physical switch. For example, the SDN controller stores a mapping table of VLANs and VNIs, and after acquiring a VTEP-1 to which the physical switch belongs and a VTEP-2 to which the virtual machine belongs, may select a VNI from the VNI mapping table, where if the VLAN identifier of the physical machine is 1, the VLAN identifier of the virtual machine is 2, and the VNI used for communication between the virtual machines is 10001, the SDN controller issues VLAN < - - > VNI mapping table 1< - - >10001 to the VTEP-1 to which the physical machine belongs, and issues VLAN < - - > VNI mapping table 2 ← → 10001 to the VTEP-2 to which the virtual machine belongs.
In step 260, the first physical switch and the second physical switch implement data exchange between the physical machine and the virtual machine according to the first mapping relationship and the second mapping relationship, respectively. For example, when receiving data sent by a physical machine, a first physical switch converts a VLAN to which the physical machine belongs into a first VNI according to a first mapping relationship, encapsulates the first VNI into a data packet, and sends the data packet to a second physical switch; the second physical switch converts the first VNI into a VLAN to which the virtual machine belongs according to the second mapping relation; or when the second physical switch receives the data sent by the virtual machine, the second physical switch converts the VLAN to which the virtual machine belongs into a second VNI according to the second mapping relation, packages the second VNI into a data packet and sends the data packet to the first physical switch; and the first physical switch converts the second VNI into the VLAN to which the physical machine belongs according to the first mapping relation.
In this embodiment, the VTEP function previously implemented on the OVS is promoted to the physical switch, and under one physical switch, isolation between virtual machines is no longer implemented by using VNI, but is separated by using the conventional VLAN. In order to realize the intercommunication between the virtual and real devices under different physical switches, especially the intercommunication between the virtual and real machines under different VLANs, each VTEP is required to realize the conversion between the VLAN and the VNI.
Fig. 3 is a schematic structural diagram of an embodiment of a virtual data center networking system in a heterogeneous environment according to the present invention. The system comprises a cloud management platform 310, an SDN controller 320, a service management platform 330, a first physical switch 340 and a second physical switch 350, wherein the first physical switch 340 and the second physical switch 350 provide VTEP functionality.
The cloud management platform 310 is configured to create a virtual machine and create a VLAN to which the virtual machine belongs on the OVS.
The SDN controller 320 is configured to create a VLAN to which a physical machine belongs on the first physical switch 340; and the second key information is used for sending the second key information to the first physical switch hooked by the physical machine and the second physical switch hooked by the virtual machine according to the first key information. In one embodiment, the SDN controller 310 may obtain, through the EVPN protocol, the VLAN identifier to which the virtual machine belongs and the VTEP location information where the virtual machine belongs.
The second key information is, for example, a mapping relationship between the VLAN and the VNI. For example, the SDN controller issues, to a first physical switch attached to a physical machine, a first mapping relationship of a first VNI between a VLAN to which the physical machine belongs and the first physical switch, and issues, to a second physical switch attached to a virtual machine, a second mapping relationship of a second VNI between the VLAN to which the virtual machine belongs and the second physical switch.
The service management platform 330 is configured to issue interworking requirements of the virtual machine and the physical machine to the cloud management platform 310 and the SDN controller 320, respectively, so that the cloud management platform 310 and the SDN controller 320 interact with the first key information. The first key information includes the VLAN to which the virtual machine belongs and the attached physical switch information.
The first physical switch 340 and the second physical switch 350 are used for realizing data exchange of the physical machine and the virtual machine according to the second key information. For example, when data sent by the virtual machine arrives at the second physical switch, the carried VLAN is converted into the corresponding VNI by the second physical switch according to the second mapping relationship, and when the encapsulated data packet arrives at the first physical switch, the first physical switch converts the VNI into the corresponding VLAN according to the first mapping relationship.
In this embodiment, the SDN server issues the mapping relationship between the VLAN and the VNI to each physical switch, and flexible interworking between the virtual machine and the physical machine can be achieved. The embodiment can fully utilize the physical and virtual resources which are currently deployed in the existing network, accelerate the deployment speed of a large two-layer network, and reduce the application migration requirement which is originally deployed on a physical machine.
In another embodiment of the present invention, as shown in fig. 4, the cloud management platform 310 is used to create virtual machines VM1, VM2, VM3, etc., and create a VLAN to which the virtual machine belongs on the OVS. The VLAN to which the virtual machine belongs is transmitted to the second physical switch 350 to which the virtual machine is attached. The cloud management platform 310 is further configured to send the VLAN identifier to which the virtual machine belongs and the VTEP location information where the virtual machine belongs to the SDN controller, that is, the cloud management platform 310 sends the location information of the second physical switch 350 to the SDN controller 320. The first physical switch 340 implements the function of the VTEP where the physical machine is located, and the second physical switch 350 implements the function of the VTEP where the virtual machine is located.
The SDN controller 320 is configured to create a VLAN to which the physical machine P1, P2 belongs on the first physical switch 340; and is further configured to issue, to a first physical switch 340 attached to the physical machine, a first mapping relationship of a first VNI between the VLAN to which the physical machine belongs and the first physical switch, and issue, to a second physical switch 350 attached to the virtual machine, a second mapping relationship of a second VNI between the VLAN to which the virtual machine belongs and the second physical switch.
The service management platform 330 is configured to issue interworking requirements of the virtual machine and the physical machine to the cloud management platform 310 and the SDN controller 320, respectively.
The first physical switch 340 and the second physical switch 350 implement data exchange of the physical machine and the virtual machine according to the first mapping relation and the second mapping relation, respectively. For example, when receiving the data sent by the physical machine P1, the first physical switch 340 converts the VLAN to which the physical machine P1 belongs into the first VNI according to the first mapping relationship, encapsulates the first VNI into a data packet, and sends the data packet to the second physical switch 350; the second physical switch 350 converts the first VNI into a VLAN to which the virtual machine VM1 belongs according to the second mapping relationship; or when receiving the data sent by the virtual machine VM1, the second physical switch 350 converts the VLAN to which the virtual machine VM1 belongs into the second VNI according to the second mapping relationship, encapsulates the second VNI into a data packet, and sends the data packet to the first physical switch 340; the first physical switch 340 translates the second VNI to the VLAN to which the physical machine P1 belongs according to the first mapping.
