This identifies packets that enter the network, but do not match an existing flow. The application determines whether the source and destination are on the same virtual network; if so, the application signals the controller to continue the flow creation. This filter is in fact a simple layer 2 (MAC)-based network virtualization, which enables users to create multiple logical layer 2 networks in a single layer 2 domain.

Important points:

• Enabling the VNK requires starting the Floodlight controller with quantum.properties instead of floodlight.default.properties.
• Enabling the VNF using curl can be achieved using the following command:

      curl -X PUT -d '{ "network": { "gateway": "20.0.0.1", 
      "name": "DemoNetwork" } }'
      http://localhost:8080/networkService/v1.1/tenants
      /default/networks/DemoNetwork1

• For the virtual network:
  
  • Name: DemoNetwork
  • ID: DemoNetwork1
  • Gateway: 20.0.0.1
  • Tenant: default
• Adding a host to the preceding named network DemoNetwork is done using the following command:

      curl -X PUT -d '{"attachment": {"id": "DemoNetwork",
      "mac":"00:00:00:00:00:A2"}}'  
      http://localhost:8080/networkService/v1.1/tenants/default/
      networks/DemoNetwork1/ports/port10/attachment

• The host settings are:
  • MAC address: 00:00:00:00:00:A2
  • Port: port10
