At the conclusion of this class the students are expected to be able to:

• Understand the basics of multiplexing, e.g., statistical multiplexing
• Understand the layered structure of protocols
• Understand the importance of standards and who sets them
• Understand the basics of network protocols, including, datagram/virtual circuit switching/forwarding, access control, data link control and, IP, transport (TCP & UDP).
• Understand the tradeoffs involved in network design in a variety of environments - LAN and WAN, diverse link rates, and varied error and delay conditions
• Perform simple analytic performance and design trade-off studies
• Perform simulation-based performance and design trade-off studies
• Understand the basics of network security, including public/private key systems, digital signatures, key distribution systems, and certificate authorities
• Use network analysis tools, e.g., Wireshark , traceroute , ping, and simulation (ExtendSim)
• Be fluent in the language of communication networks, i.e., understand the meaning of networking terms and abbreviations

• Advice on Writing
• Most colleges and universities have a writing center, a place for students to talk about their writing with trained peer consultants. At KU, we call our writing centers Writer's Roosts. When you visit, bring your work in progress and an idea of what you would like to work on-organization, support, documentation, editing, etc. The Roosts are open in several different locations across campus; please check the website at www.writing.ku.edu for current locations and hours. The Roosts welcome both drop-ins and appointments, and there is no charge for their services. For more information, please call 864-2399 or send an e-mail to writing@ku.edu.

Academic Integrity and Plagiarism

The department, school and university have very strict guidelines regarding academic misconduct. Obviously, copying is not allowed on exams. Students are expected to submit their own work on individual homework and projects. Lending or borrowing all or part of a simulation model or program from another student is not allowed. Students ARE allowed to borrow and modify any code on this class web site in their projects. Instances of cheating will result in a referral to the department chairman and the dean of engineering.
All sources in your written work (project reports) must be properly referenced; if you use a source from the literature or the idea of another for your work you must reference it. If you quote or copy a block of text, it must be cited and included in quotation marks (if a sentence or less in length) or in block quote style (if more than a sentence in length). If you paraphrase text (reword a phrase, sentence, or paragraph), you must also quote or blockquote followed by “[paraphrased]” in addition to proper citation. Figures taken from other sources must be referenced.

I recommend that you take intermediate notes from which you write your own words. I strongly recommend that you not write in one window while displaying the work of others in another window; this is asking for trouble. “Unintentional” paraphrasing is also not an acceptable excuse for academic misconduct.
