Embodiment 1
[0041] The packet forwarding method of the distributed virtual switch system according to Embodiment 1 of the present application is executed by a controller. Such as Figure 4 As shown, the method includes the following steps:
[0042] Step S402, after the OF switch is created, create an aggregation group corresponding to the OF switch, and add at least two uplink ports connected to the physical switch on the OF switch to the aggregation group;
[0043] In the step S402, create an aggregation group corresponding to the OF switch, and add at least two uplink ports connected to the physical switch on the OF switch to the aggregation group, including the following two aspects:
[0044] (1) OF switch creation process
[0045] Step 11: After the VMM Center (virtual machine management software) executes the operation of adding a host (that is, a server), it notifies the server to create an OF switch;
[0046] Step 12: After receiving the notification, the server creates an OF sw...
Embodiment 2
[0125] as Figure 5 The shown distributed virtual switch system is taken as an example to describe the method in the first embodiment above in detail. exist Figure 5 Among them, the OF switch is respectively connected to the virtual machine VM1-VM3 through the dvport ports: dvport1-dvport3, the MAC addresses of dvport1-dvport3 are respectively MAC1-MAC3, and these three dvport ports belong to VLAN1. There are two links between the OF switch and the physical switch ToR connected to it. These two links are aggregated through the link aggregation technology, that is, the two uplink ports connected to the ToR on the OF switch: uplink1 and uplink2 are added to the same aggregation group. The two physical ports connected to the OF switch on the ToR: T1 and T2 are added to the same aggregation group.
[0126] The controller adds an entry in the aggregation group information table according to the above step S402, as shown in Table 4-1:

[0129] The...
Embodiment 3
[0136] For the method in the first embodiment above, a controller of a distributed virtual switch system is provided in the embodiment of the present application. Such as Image 6 As shown, the controller includes the following modules: creating and adding module 101, receiving module 102, aggregation processing module 103, entry generating module 104 and sending module 105, wherein:
[0137] Create an adding module 101, which is used to create an aggregation group corresponding to the OF switch after the OF switch is created, and add at least two uplink ports connected to the physical switch on the OF switch to the aggregation group;
[0138] The receiving module 102 is configured to receive the uplink message forwarded by the OF switch, wherein the uplink message is received by the OF switch through a dvport port connected to the VM;
[0139] The aggregation processing module 103 is configured to determine the aggregation group corresponding to the OF switch after the recei...
