Recall
: The network layer has two functions.
Forwarding
: The process of a router sending a packet toward its destination — the data plane.
Routing
: The process of determining the path a packet takes to its destination — the control plane.
Two ways to structure the network control plane (link!)
Per-router control: The traditional approach, which remains popular.
Logically centralized control: Used in software-defined networking (SDN).
