Example Embodiment
[0046] see figure 1 As shown, in the initialization process of the present invention, two virtual switches OVS-A and OVS-B are created on the network node and the computing node respectively, as follows:
[0047] #ovs-vsctl add-br OVS-A / / Create an OVS bridge, which is a virtual machine switch
[0048] #ovs-vsctl add-br OVS-B / / Create an OVS bridge, which is a virtual machine switch
[0049] OVS-A is used to connect to the external network and add a physical interface eth1 to the external network:
[0050] #ovs-vsctl add-port OVS-A eth1
[0051] Then create a VETH device to connect OVS-A and OVS-B. In the following operations, vethA-1 and vethA-2 are the two ports of the VETH device vethA:
[0052] #ip link add vethA-1 type veth peer name vethA-2 / / Create vethA-1 and vethA-2
[0053] #ifconfig vethA-1 up / / Activate vethA-1 port
[0054] #ifconfig vethA-2 up / / Activate vethA-2 port
[0055] #ovs-vsctl add-port OVS-A vethA-1 / / vethA-1 is connected to bridge VOS-A
[0056] #ovs-vsctl add-port ...
