Messages flow across an SDN controller's:
Northbound APIs:
• Messages which help in read/write state of the network and developing flow tables within the
state management layer.
• Notifications for the state-change events.
• The interaction between the controller and network control applications is done through the
northbound interface.
• Network control applications send messages to the controller.
Southbound APIs:
• Messages which help for the up-to-date view of the network's state like message for the
attached link has gone up or down, new devices are joined the network, or indications of the
device is up or down.
• Controller's southbound interface is the communication among the controller and the controlled
devices. Controlled devices are the recipients of the messages sent form the controller.

Answer:
polymorphic
Explanation:
An example of polymorphic reference, suppose you have 3 classes: Main, Product and SpecificProduct. If SpecificProduct extends Product this means it is a product class but with something else to complement.
Say you want to reference an object of product in the main class, you can do it the classic way:
Product pd = new Product();
Or you can do it polymorphic, like this:
Product pd = new SpecificProduct();
The program will accept just fine because SpecificProduct is extending Product. When you do it like this, we say the reference you made was a polymorphic reference
