Wide Area Network (WAN) Crossword Puzzle

What's Going On Here?

It takes a lot of elements to create a Wide Area Network. You need to know a lot about hardware, software, protocols, standards, and more in order to properly create a WAN. Just look at this simple diagram below and you can see just some of the parts of the puzzle. We created this diagram for one of our clients who was trying to teach about ways to simplify the process of getting a small business connected to the Internet. Of course, this was the "before" picture!

The crossword puzzle tests your knowledge of basic WAN concepts from ISDN to T1 to DSL and more. We recommend some links and excellent books below for you to use to fill in whatever gaps you may have about Wide Area Networks. If you already know a lot about WANs, you can try the exercise beneath this one that covers three very popular network protocols, AppleTalk, NetWare and TCP/IP. As if there weren't enough WAN buzzwords!

 
Network Protocols Exercise

 

What's Going On Here?

Trainers have used the OSI (Open Systems Interconnect) Model for years to try to explain how network protocols operate. It is important to know what parts of the protocols reside at the different layers of the model. Why? Simple. If you want to control your network and its performance, you have to use tools that can take control at the appropriate layer. Those tools are often categorized by the layer of the OSI model on which they operate.

For example, a router or layer-3 switch can control traffic at Layer 3 of the OSI model (the network layer). A traffic shaping product like Packeteer's PacketShaper, can control traffic based on characteristics found at Layer 2, 3, 4 and above of the OSI model, giving you more flexibility on which traffic gets highest or lowest priority.

Shown here are three commonly used protocol stacks. These are the NetWare suite, AppleTalk, and the most ubiquitous protocol, TCP/IP. Your job is to click and drag various components of these protocol suites into their appropriate OSI model layers until you've completely built the stacks.

Learn About Protocol Analysis

Would you like to learn how to analyze the protocols on your Local or Wide Area Network? We at WKMN have recently formed a partnership with a leading protocol analysis training company. They have classes and videos available to help you become a master analyzer using products from Shomiti, Network Associates, and Agilent Technologies. Click here to e-mail us and we'll put you in touch with our favorite Protocol Analysis school!

Additional Resources and Books:

Finding the right resource on protocols really depends on what you are trying to learn. There are so many books and on-line resources that they can boggle the mind! Here are just a few of my favorite book recommendations and links. If you are looking for something special, feel free to contact us. We may be able to point you in the right direction!
