ITPEC FE Morning October 2021 Question 34
ITPEC FE Morning October 2021 — Question 34 of 80
SDN (Software-Defined Networking) with OpenFlow — identify the correct definition of SDN.
SDN separates two planes:
- Control plane — centralized software (SDN controller) makes routing decisions
- Data plane — network devices (switches) only forward packets as instructed
OpenFlow is the protocol that connects the controller to the switches.
Why not others:
- (b) BPA — business process analysis using DFD and activity diagrams
- (c) IoT + RFID — unrelated mix of IoT and distribution optimization
- (d) CDN — content delivery network for efficient content streaming
Key idea: SDN = centralized software control + dumb forwarding hardware.
