Hi Murali, When creating network, the plugin will capture the networkUUID, tenantID, vlan and send a request to the controller to create a virtual network. Controller will create an addressSpace construct to match the vlan so that all device in the addressSpace has unique mac and ip, then create a virtual network. The membership of the virtualNetwork is based on a tag rule. A tag rule is that any device with the tag will be classified to the virtual network.
When a VM is created, BigSwitchVnsElement.java will send a request to the controller to create a port and attachment for the VM. The port contains the networkuuid. The attachment contains the VM's mac address. The controller then associates the VM with its network tag. At this point, nothing is happening to the switches yet. When VM sends packets, the VM's network association is determined based on its first packet. If the destination is in the same virtual network, the controller will permit the flow and set up a end-to-end flow. When setting up the flow, vlan is programmed on the switches along the route. The switches can be virtual or OF-enabled physical switches. Then the network is destroyed, the plugin notifies the controller, which then removes the tag and virtual network. Hope the explanation clarifies the workflow. Let me know if you have more question.
