为了更好的描述本发明，下面通过一个具体的实施例对本发明进行详细地描述。In order to describe the present invention better, the present invention will be described in detail through a specific embodiment below.
如图1所示，在云平台中有两台虚拟机，该两台虚拟机分别为虚拟机1、虚拟机2，此外，在第一虚拟交换机上对上述两台虚拟机分别打上不同的vlan号，例如，根据本发明的一个实施例，如图1所示，虚拟机1对应的标号vlan3，虚拟机2对应的标号vlan4，其中，该第一虚拟交换机为标准虚拟化虚拟交换机(vSS)或分布式虚拟虚拟交换机(vDS)，同时，将第一虚拟交换机中和第二虚拟交换机连接的虚拟网口1配置为TRUNK端口(即可以通过所有vlan号的数据包)，这样就可将虚拟机1、虚拟机2发送的数据包流入该第二虚拟机中，另外，在第二虚拟机中的第二虚拟交换机上设置OVS流规则，使得携带有vlan3的数据包从3号端口出去，携带有vlan4的数据包从4号端口出去，随后使用虚拟网络设备VETH连接第二虚拟交换机和第三虚拟交换机以实现虚拟网络流控，此外，可以理解，也可根据实际需求对第二交换机和第三交换机进行设置，例如，根据本发明的一个实施例，第二虚拟交换机为OVS(Tunnel)，第三虚拟交换机为OVS(Integ)，同时，可根据实际需求对与第三虚拟交换机连接的虚拟机业务类型和数量进行设置，例如，根据本发明的一个实施例，如图1所示，该虚拟机业务1涉及隧道业务，该虚拟机业务2涉及VLAN业务，随后上述虚拟业务1和虚拟业务2连接对应的物理虚拟交换机。As shown in Figure 1, there are two virtual machines in the cloud platform, the two virtual machines are respectively virtual machine 1 and virtual machine 2, in addition, on the first virtual switch, the above two virtual machines are marked with different vlans respectively For example, according to an embodiment of the present invention, as shown in FIG. 1, the label vlan3 corresponding to virtual machine 1, and the label vlan4 corresponding to virtual machine 2, wherein the first virtual switch is a standard virtualized virtual switch (vSS) or a distributed virtual virtual switch (vDS), and at the same time, configure the virtual network port 1 connected to the second virtual switch in the first virtual The data packets sent by machine 1 and virtual machine 2 flow into the second virtual machine. In addition, OVS flow rules are set on the second virtual switch in the second virtual machine, so that the data packets carrying vlan3 go out from port No. 3, The data packet carrying vlan4 goes out from port 4, and then uses the virtual network device VETH to connect the second virtual switch and the third virtual switch to realize virtual network flow control. In addition, it can be understood that the second switch and the third virtual switch can also be configured according to actual needs. The third switch is set, for example, according to one embodiment of the present invention, the second virtual switch is OVS (Tunnel), and the third virtual switch is OVS (Integ). Virtual machine service type and quantity are set, for example, according to an embodiment of the present invention, as shown in Figure 1, this virtual machine service 1 relates to tunnel service, and this virtual machine service 2 relates to VLAN service, then above-mentioned virtual service 1 and virtual Service 2 is connected to the corresponding physical virtual switch.
此外，该网络设备虚拟化系统的具体流程如下：In addition, the specific process of the network device virtualization system is as follows:
1、在vSS/vDS上面实现虚拟机的vlan号互斥，每个第一虚拟机都需要不同的vlan；1. The vlan numbers of the virtual machines are mutually exclusive on the vSS/vDS, and each first virtual machine needs a different vlan;
2、vSS/vDS需要和第二虚拟交换机通过trunk口相连接；2. vSS/vDS needs to be connected to the second virtual switch through the trunk port;
3、使用虚拟网络设备VETH连接两个OVS接口；3. Use the virtual network device VETH to connect two OVS interfaces;
4、设置OVS流规则，该规则具体如下：4. Set the OVS flow rules, the rules are as follows:
将vlan3的流量从3号端口发出；Send vlan3 traffic from port 3;
将vlan4的流量从4号端口发出；Send vlan4 traffic from port 4;
将3号端口的流量从1号端口发出；Send the traffic of port 3 from port 1;
将4号端口的流量从1号端口发出。Send the traffic of port 4 from port 1.
当然可以理解，本发明可根据实际需求对OVS流规则进行设置，本发明对此不做限定。Of course, it can be understood that the present invention can set the OVS flow rules according to actual requirements, which is not limited in the present invention.
综上所述，借助于本发明的上述技术方案，通过设置在云平台上的至少一个第一虚拟机、一第一虚拟交换机、一第二虚拟机，每个第一虚拟机与第一虚拟交换机连接，并且第一虚拟交换机与第二虚拟机连接，从而将第一虚拟机发送的数据包通过该第一虚拟交换机导入到第二虚拟机中进行处理，同时，第二虚拟机包括：第二虚拟交换机，与第一虚拟交换机连接；第三虚拟交换机，与第二虚拟交换机连接，并且第二虚拟交换机和第三虚拟交换机通过虚拟网络设备VETH连接，进一步实现了虚拟网络流控。To sum up, with the help of the above technical solution of the present invention, through at least one first virtual machine, a first virtual switch, and a second virtual machine set on the cloud platform, each first virtual machine and the first virtual The switch is connected, and the first virtual switch is connected to the second virtual machine, so that the data packets sent by the first virtual machine are imported into the second virtual machine through the first virtual switch for processing, and at the same time, the second virtual machine includes: The second virtual switch is connected to the first virtual switch; the third virtual switch is connected to the second virtual switch, and the second virtual switch and the third virtual switch are connected through a virtual network device VETH, further realizing virtual network flow control.
