When Dijkstra's algorithm is used to determine shortest path routes in SDN: (choose all that apply)

Question

Accepted Answer

Packet switches send link updates to the SDN controller and not to each other.

Accepted Answer

The link-state routing application interacts with the controlled switches to get updated link state

Accepted Answer

Dijkstra's algorithm is executed as a separate application, outside of the packet switches.

Accepted Answer

The link-state routing application then interacts with the flow table manager, which determines the flow tables to be updated.

Answer

Dijkstra's algorithm cannot be used in SDN
