What is Understanding Network Layer Protocols about?

The network layer is responsible for transferring data between hosts. It uses two approaches: virtual circuits (VCs), which establish connections like circuit switching; and datagram networks, which forward individual packets without connections. Routing determines the overall path between sources and destinations, while forwarding refers to moving packets between adjacent links locally. VCs require connection setup and maintain routing state, while datagram networks forward based only on destination addres
