SDN — Software-Defined Networking
Uses software control and abstraction for network behavior.
Why learn SDN — Software-Defined Networking?
Uses software control and abstraction for network behavior.
Where it came from
A centralized controller does not remove the need for resilient forwarding.
- Memory aid (a learning cue, not the expansion): Software Defines the Network's rules.
Build your understanding
Work through these exercises in order. Try the task before opening a reference.
- Without looking, expand SDN: Software-Defined Networking.
- Recall this memory aid: Software Defines the Network's rules.
- Explain the practical use: Uses software control and abstraction for network behavior.
- Explain this distinction: A centralized controller does not remove the need for resilient forwarding.
- Identify SDN in a device specification, architecture diagram, or system inventory.
