1. Datagram-based network layer: Forwarding, Routing.
2. VC- based network layer: Forwarding, Routing, Call setup.

The most important functions in a datagram network include forwarding and routing. The most important functions in a virtual circuit network include forwarding, routing and call setup.

  • Forwarding in networking can be defined as the router-local action by each router when a packet arrives at one of the interfaces.

  • Routing in networking can be defined as the process which determines the end-to-end pathways that packets take from the source to the corresponding destination.

  • Finally, call setup refers to the process of establishing a virtual circuit across a network.

In conclusion, the most important functions in a datagram network include forwarding and routing. The most important functions in a virtual circuit network include forwarding, routing and call setup.
