When building a LAN that satisfies the needs of a small or medium-sized business, your plan is more likely to be successful if a hierarchical design model is used. Divided into discrete layers. Each layer has a specific purpose. Becomes modular – maintenance, performance.Interfaces with end devices. Routers, switches, bridges, wireless access points. Provides a means of connecting and controlling which devices are allowed to communicate on the network.

The data link layer needs to pack bits into frames, so that each frame is distinguishable from another. Our postal system practices a type of framing. The simple act of inserting a letter into an envelope separates one piece of information from another; the envelope serves as the delimiter.

Protocols for wireless applications Wireless data networks present a more constrained communication environment compared to wired networks. Because of fundamental limitations of power, available spectrum, and mobility, wireless data networks tend to have less bandwidth than traditional networks, more latency than traditional networks, less connection stability than other network technologies, and less predictable availability.

This lab focuses on configuring a basic router-to-router WAN and then troubleshooting Layer 1 cabling problems and workstation Layer 3 IP addressing problems. Note: The two routers need to be preconfigured by the instructor or lab assistant to have the correct IP addresses on their LAN and WAN interfaces. Router A will provide the clocking signal as DCE. Use the prior lab “Basic Routed WAN” to set up this lab prior to starting the troubleshooting.
