   • Two main functions of network layer: – Addressing – Packet switching (routing + packet forwarding) • Allow packets to traverse multiple networks • Deliver packet to specified destination host • Best effort: network delivers packets as reliably and as quickly as it can (but provides no guarantee of delivery)

   Now that we have discussed layered networks in the abstract, it is time to look at some examples. We will discuss two important network architectures: the OSI reference model and the TCP/IP reference model.

   The TCP/IP 5-Layer Model. The Department of Defense (DoD) TCP/IP 5-layer model was created in 1969. Table 1.2 shows the layers of this model and the service pro-vided by each layer. With this model, aimed specifically at TCP/IP conventions, we can identify the protocols at each layer, as shown in Table 1.3.

   Note:The Physical Layer of the OSI model is only part of a LAN (Local Area Network). Layer 2 – The Data Link Layer Layer 2 of the OSI model provides the following functions: •Allows a device to access the network to send and receive messages • Offers a physical address so a device’s data can be sent on the network

   Network Protocol: Semantics • Protocol semantics define when PDUs can be sent, and what response is needed • Define who can send PDUs, and when they can be sent • Define roles for the hosts (e.g., client and server, peer-to-peer) • Define what are the entities that communicate and how they are named • Define how errors are handled
