QuestionQ1350

Automation and Programmability

What is the function of the controller in a software-defined network?

  • A forwarding packets
  • B multicast replication at the hardware level
  • C making routing decisions
  • D fragmenting and reassembling packets
Explanation

In a software-defined network, the controller provides the control plane: it computes paths and policy-based forwarding behavior and installs rules on network devices. The actual packet forwarding is performed by the switches or routers in the data plane, not by the controller itself.
