Where is the interface between the control plane and data plane within the software-defined architecture?
Click on the arrows to vote for the correct answerA. B. C. D.
In a software-defined architecture, the control plane is responsible for making decisions about how data packets should be forwarded, while the data plane is responsible for actually forwarding the packets based on those decisions. The interface between the control plane and data plane is where these two functions meet and interact.
Option A ("application layer and the management layer") is not correct, as the management layer is typically responsible for configuring and monitoring the network, rather than for making forwarding decisions.
Option B ("application layer and the infrastructure layer") is also not correct, as the infrastructure layer typically provides the physical or virtual resources that the network relies on, rather than serving as an interface between the control and data planes.
Option C ("control layer and the application layer") is not correct either, as the application layer is typically not involved in forwarding decisions.
The correct answer is option D ("control layer and the infrastructure layer"). In a software-defined architecture, the control layer is responsible for managing the network and making forwarding decisions based on policies and network conditions. The infrastructure layer is responsible for implementing those decisions by forwarding packets according to the configured rules. The interface between the control and infrastructure layers is where the forwarding decisions made by the control layer are translated into actual forwarding actions by the infrastructure layer.
