The paper examines chapter four of "Computer Networking" where Kurose and Ross discuss the network layer that implements host-to-host communication service. The paper reviews how the authors address the network layer's functions and services, including distinguishing between the network layer's forwarding and routing functions. The paper then outlines how they discuss the network layer's forwarding services and routing services in detail. This paper argues that chapter four provides a strong overview of how the network layer allows hosts to communicate, and also how all components in the network, including hosts, become parts of the network layer.

From the Paper:

"James and Ross begin their discussion by explaining the various functions and services of the network layer. While many people interchange the terms forwarding and routing, they are actually distinct actions. James and Ross define forwarding as "the router- local action of transferring a packet from an input link interface to the appropriate output link interface" (p.318). To differentiate between the two, James and Ross define routing as "the network- wide process that determines the end- to- end paths that packets take from source to destination" (p.318). While these distinctions may seem unimportant, forwarding is something done at each router, while the routing refers to the packet's entire trip (James and Ross, p.318). In addition to forwarding and routing, some computer networks engage in a third function referred to as connection set-up, which "allows the sender and receiver to set up the needed state information" for data flow (James and Ross, p.320). In addition to the forwarding and routing functions, computer networks can offer guaranteed packet delivery, guaranteed delivery within a bounded amount of time, in-order packet delivery, guaranteed minimal bandwidth, guaranteed maximum jitter, and security services (James and Ross, p.321). What they make clear is that the network layer can provide a number of services that are connected to the routing and forwarding functions."
