Network Layer Data Plane: Chapter 4 Quiz

To understand the principles behind network layer services, focusing on data plane instantiation, implementation in the Internet, IP protocol, NAT, middleboxes, network layer service models, forwarding versus routing, how a router works, addressing, generalized forwarding, and Internet architecture.

The data plane focuses on the instantiation and implementation of network layer services, while the control plane deals with the decision-making and configuration of the network elements.

The components inside a router include input ports, switching, output ports, buffer management, and scheduling.
