GRADING POLICY

On their respective due dates course assignments requiring hard copy submission are to be turned in during class and those requiring electronic submission are to be completed before midnight. No assignment will be accepted for credit after its deadline.

If you have questions concerning a grade you receive on any course assignment, it is your responsibility to inform me within 1 week of the graded assignment being returned. Grades will not be discussed after that time.

After rounding your numeric score to the nearest integer, your course letter grade will be assigned according to the scale: A = 90-100, B = 80‑89, C = 70‑79, D = 60‑69, and F = 0‑59. 

IMPORTANT DATES

⁺ The guest lecture (GL) dates and GL form due dates are subject to change and will be announced in class once they have been confirmed. Each GL form will be due at the beginning of class on its due date.

COURSE WEB SITE

Access to the course website is through Vista, the University’s course management system. You can log on to Vista by going to http://vista8.kent.edu and entering your username and password.

MODULE PREP EXERCISES

Each module prep exercise will emphasize material from the corresponding course module and consist of 10 objective questions. It will be available on Vista and graded online.

MODULE REVIEW EXERCISES

For each module review exercise you are to post 4 true/false questions to Vista, and each valid question will be worth 0.125 points. For a question to be considered valid, it must be clear, unambiguous, your own original work, and appropriate for testing concepts covered in the corresponding course module, and the correct answer must be included.

EXAMINATIONS

The exams will emphasize the material discussed in class.  A makeup exam (which may be different from the original) will only be given if you have a legitimate excuse (i.e., sickness, athletic event, religious observation, military responsibility, or death in immediate family), obtain my permission prior to the scheduled exam time, and provide written documentation. Otherwise you will receive a zero for a missed exam.

While taking an exam, you may refer to one 1-sided 8 ½ x 11” page of notes which you are to show me when you turn in your exam.  I strongly recommend being very selective in deciding what to include on the page. This should help you to prepare better for the exam and save you time while taking the exam. Except for your page of notes, each exam will be closed book and closed notes.

GUEST LECTURE FORMS

You are required to attend both guest lectures and to submit a guest lecture form (available on Vista) for each. Carefully follow all the instructions provided on the form and submit a hard copy.  

NETWORK TOOLS EXERCISE

A network tools exercise will be announced in class towards the end of the semester.

COURSE PROJECT

Each student is to write a project report on some topic from the field of data communications and present it in class. You have the option of selecting your topic (which must be relevant to the course and add new information beyond the material I cover) or having me assign one for you. If you choose the former option, you must obtain my approval by the project topic due date. You may do this during office hours or by e-mail. If you do not obtain my approval of a topic by the due date, I will assign one for you.

For ideas on possible project areas, I suggest that you browse through the text, explore the Internet, visit a library, and/or consult the following list:

Computer telephony integration/Unified communications

Data, audio, and video compression

Directory services and protocols (AD, LDAP)

Domain name system

Fiber optic networks (PONs, SONET, WDM)

Messaging and collaboration tools

Network protocols (TCP/IP, IPv6, MPLS)

Network security

Peer-to-peer file sharing/BitTorrent

Regulation and deregulation (AT&T divestiture, telecom legislation, net neutrality)

Radio-frequency identification  

Routing algorithms and protocols

Video communications (IPTV, videoconferencing)

Virtual private networks 

Virtualization

Voice over IP

Wireless communications (IEEE 802.11 WLANs, Bluetooth, WiMax, cellular)

Wireless sensor networks

Note that your topic does not have to be on this list, nor is it guaranteed that I will approve a topic that is on the list.

PROJECT OUTLINE

Each student is to submit in hard copy format a project outline. It should be at least 1 page long and provide a detailed outline of the topics and subtopics to be addressed in your project. Use size 12 Times New Roman font and 1.5 line spacing.

PROJECT REPORT

The project report should have (1) a cover page, (2) table of contents, (3) executive summary, (4) body (with the pages numbered and at least 5 pages of text), (5) bibliography, and (6) appendix with illustrative figures and tables.

The cover page should provide (1) the project title, (2) your name, and (3) the date. The table of contents should include all major components of the report. The executive summary should be one page long and give a clear, complete, and concise summary of the project.

The body of the report should have (1) an introduction, (2) a section for each subtopic, and (3) a conclusion. It should also address each of the following areas as they relate to your topic: (1) background and options; (2) business applications and implications; (3) strengths and limitations versus alternatives; and (4) future trends.

The bibliography should include a list of all your references, and each reference should be cited wherever appropriate in your report. The figures and tables should be numbered systematically and consistently, have captions, and be discussed and referenced at appropriate locations in the report.

For the executive summary and body of the report, use size 12 Times New Roman font, 1.25 inch margins (for all 4 margins), 1.5 line spacing, and left justification (only). Insert 1 blank line after each section and, instead of separating paragraphs with blank lines, start each paragraph with a tab character.

The report will be graded according to how well you satisfy the above requirements as well as the following 5 criteria: professionalism; breadth; depth; clarity; and effort.

PROJECT PRESENTATION

Each student is to present his/her project in class at the end of the semester. When giving your presentation, it is not necessary to include all the details in your report. You are strongly encouraged to (1) use PowerPoint, (2) not read the information you present, (3) begin the presentation by introducing yourself and your topic and providing an outline of the subtopics to be addressed, (4) include a hands-on demonstration if appropriate, (5) conclude the presentation with a summary of the key findings, and (6) rehearse your presentation to ensure that it fits the allotted time (this will be based on the class size and announced in class approx. 2 weeks before the presentations begin). You may assume that a computer and projector will be provided, although I strongly recommend that you have a backup plan in case of equipment failures. If you wish to use any additional equipment, you should notify me at least one week in advance and schedule a time to test the equipment in the classroom.

The presentation will be graded according to the following criteria: breadth; depth; professionalism; pace/diction; eye contact; visual aids, effort; time management; enthusiasm/innovation; and clarity/organization.

PROJECT PRESENTATION FORM(S)

You are required to attend all the project presentations at the end of the semester and to submit project presentation forms (available on Vista) for 3 presentations, with at least 1 from each of the class meetings in which projects are presented. On each form enter your name, the date, the presenter’s name, and the topic being presented. Then complete the form during class making sure that you write legibly and carefully follow all the instructions provided.

ATTENDANCE AND CLASSROOM BEHAVIOR

Attendance is not mandatory but is highly recommended if you wish to do well in the course. You are responsible for all material presented in class and should not expect any special consideration if you miss material due to being absent.  

You are expected to be respectful of our guest speakers, other students, and the instructor at all times during the semester. Come to class on time and stay until the class has ended. Unless you have a legitimate reason for doing so, do not come to class late or leave early. It is not fair to cause a disruption by the noise and disturbance of a late arrival or early departure. Any time you have questions ask them, in class, during office hours, or via e-mail. This is likely to benefit other students as well as you. Similarly, any time you have relevant comments, please share them. Use of cell phones or pagers is not permitted during class. They must be turned off before class begins and not turned back on until after class ends.  

COLLEGE AND UNIVERSITY POLICIES

Prerequisites: Students attending the course who do not have the proper prerequisite risk being deregistered from the class.

Academic Honesty:  Cheating means to misrepresent the source, nature, or other conditions of your academic work (e.g., tests, papers, projects, assignments) so as to get undeserved credit.   In addition, it is considered to be cheating when one cooperates with someone else in any such misrepresentation.  The use of the intellectual property of others without giving them appropriate credit is a serious academic offense.  It is the University's policy that cheating or plagiarism result in receiving a failing grade for the work or course.  Repeat offenses result in dismissal from the University.

Course withdrawal: For Spring 2010, the course withdrawal deadline is Sunday, April 4.

Students with disabilities:  University policy 3342-3-01.3 requires that students with disabilities be provided reasonable accommodations to ensure their equal access to course content. If you have a documented disability and require accommodations, please contact the instructor at the beginning of the semester to make arrangements for necessary classroom adjustments. Please note, you must first verify your eligibility for these through Student Accessibility Services (contact 330-672-3391 or visit www.kent.edu/sas for more information on registration procedures).

Course registration: Students have responsibility to ensure they are properly enrolled in classes.  You are advised to review your official class schedule (using Student Tools on FlashLine) during the first two weeks of the semester to ensure you are properly enrolled in this class and section.  Should you find an error in your class schedule, you have until Sunday, January 31, 2010 to correct the error.  If registration errors are not corrected by this date and you continue to attend and participate in classes for which you are not officially enrolled, you are advised now that you will not receive a grade at the conclusion of the semester for any class in which you are not properly registered.
