<head><title>CSCI C623 Data Communications and Networks </title></head><h1> CSCI C623 Data Communications & Networks <br>Spring 1996</h1><h2> Section 2166 -- <a href="http://www.cs.indiana.edu">Computer ScienceDepartment</a>, <a href="http://www.indiana.edu">Indiana University</a> <br>TR 11:15-12:30, Ballantine 233</h1><h2> Instructor </h2><a href="http://www.cs.indiana.edu/hyplan/prosser.html">FranklinProsser</a>, LH330E, 855-3689, email <a href="mailto:prosser@cs.indiana.edu">prosser.cs.indiana.edu</a><h2> Office hours </h2> T 12:30-1:30, W 1:30-2:25, and byappointment and by drop-in. All in LH330E.<h2> Textbook</h2> William Stallings, <em>Data and ComputerCommunications,</em> 4th edition, Macmillan, 1994.<h2> The three goals of this course </h2><p><ol><li> Learn about data communications and networks. <li> Enhance your skills at preparing and presenting material before anaudience.<li> Enhance your skills at preparing and writing a significant survey paper.</ol><p><h2>The approach </h2><p>Everyone will participate fully in the class sessions. Each student isexpected to read and reflect on forthcoming material, and be prepared to helpall of us learn more about data communications. <p>The instructor and the students will share the lecturing responsibilities,augmented by several presentations by Computer Science staff. Students willwrite at least one survey paper. Those students who present lectures on atopic will write one paper; other students will write two papers.<p>As a rough guide, I suggest that your total effort in this course might bedistributed as follows: preparation and follow-up for the course lectures:50%; preparation and presentation of each lecture topic or paper: 25%.<p>I will allocate lecture topics based on the needs of the course and thedesires of the participants. I will attempt to have the lecture schedulefirmed up by the third class period. See the <ahref="http://www.cs.indiana.edu/classes/c623/c623sch.s96">lecture schedule</a> for the currentschedule. <p>Each lecturer will develop and present the topic and will make available alist of sources and other appropriate materials to allow the members of theclass to prepare for and participate in the lectures. Following your lecture,you will assign and grade a brief but relevant homework. The lecture topicswill generally follow the structure of our main textbook. Check <ahref="#Guidelines for Lecturers">Guidelines for Lecturers</a> for some hintsfor preparing and delivering a good lecture.<p>For each paper you write, you will propose a topic, and should secure myapproval before you commence serious work. Usually, a paper will be a surveyof the present state of a rather tightly focused topic. As a general rule,avoid surveys of broad topics. You should plan to treat your topicthoroughly, using the most up-to-date sources you can find. Inevitably,students ask how long a paper must be. It is undesirable to make a rule, butI'll say that a typical paper tends to be perhaps 20 double-spaced typed orprinted pages.<p>The newsgroup for this course is <a href="news:ac.c.623">ac.c.623</a> on the IUComputer Science network. Use the newsgroup to keep tabs on class businessand to contribute useful information for the other participants in the class.There will be no classroom or final exams. On the other hand, you will beexpected to function responsibly at the graduate level throughout the course.One paper or talk will be due by March 19; the other paper or talk will bedue by April 25. I may choose to interview students on their paper(s). Thefollowing factors will contribute to your course grade:<p><ul><li> Your attendance record (yes, we will take attendance!). You are expectedto be present and to participate in all the class meetings.<p><li> If you lecture: your skill at preparing, organizing, and presenting yourmaterial. Where appropriate, this will include your timely preparation ofsource lists, handouts, and other documents associated with yourpresentation. It will also include your skill at selecting and gradinghomework problems. I will evaluate your lectures, assign a grade, and uponrequest, offer comments and criticism.<p><li> Your skill at selecting, researching, and presenting your writtenpaper(s). In addition to doing a proper job on the intellectual content ofyour paper, you will be expected to show proper technical writing skills inthe structure, style, and grammar in your paper. I will assign a grade toeach paper; the grade will reflect my judgment of writing skills, technicalcontent, and appropriateness of topic.<p><li> Your faithfulness in responding to the homework assignments, and thequality of your responses.</ul><p>In sum, the success of a seminar course such as this depends on the activeinvolvement of the participants, and the quality of your participation willbe a criterion in the grading. For normal, competent work, you should expecta B; superior work will earn an A. Inadequate work will earn a C or below.<p><p><h2>Reference sources for data communications and networks</h2>The Swain Library has some books and journals of interest for C623. Thelibrary can help you obtain other material through interlibrary loan.<p>Our textbook gives useful references at the ends of its chapters. <p>I have an extensive collection of textbooks and reference works. Check <ahref="http://www.cs.indiana.edu/classes/c623/c623refs.html">Prosser's C623books</a> for the current list and the conditions under which you may borrowmaterials. <p><h2> <a name="Guidelines for Lecturers">Guidelines for Lecturers</a></h2> We will be on a strict time schedule for our lectures, and we cannot affordto get off schedule. Therefore, you must plan your presentations carefully,and must not assume that you can take portions of the lecture time of others.<p>Be aware of how your topic fits into the total plan. Consult with peoplewhose topics overlap or touch upon yours. Allocate related or overlappingsubtopics intelligently among your peers. Most of our lectures will covermaterial presented in the textbook. If you are lecturing mainly from thetextbook, don't plan to cover every subtopic in the book. Pick severalimportant subtopics (with the instructor's help, if appropriate), and developthem in reasonable detail. If you are using sources other than the textbook,hand out a list of sources at least one week in advance of your lecture, sothat others may have a chance to prepare for your lectures. Put yourimportant sources on 2-hour reserve in the Swain library. <p>Be prepared to allow up to 2 minutes (but no more!) at the beginning of yourfirst lecture for old business. Assign one or two homework exercises relatedto your topic. Select exercises that will help illuminate important aspectsof your topic. Make the homework problems non-trivial, but not too complex ortime-consuming. You will grade the homework for your lecture.<p>Use overhead foils or the chalkboard, as you prefer. The department willprovide 10 overhead transparencies for your lecture, if you choose to usethem. You will make the transparencies yourself, either by drawing directlyon foils or by photocopying. Prior to your lectures, prepare handouts fordistribution, if appropriate.<p>When using overheads, don't use too many, and don't crowd too muchinformation into each foil. The pace of a lecture is considerably faster withoverheads than with the chalkboard, and you must allow your audience time toabsorb the material, take notes, and develop questions. <p>With a well-prepared lecture, it is common to have too much material. Youmust organize and prioritize your material so that you can fit within yourallocated time without rushing! If toward the end of the lecture you see thatyou won't finish all the good stuff you've prepared, don't try to rush onthrough new topics. You will give a much better lecture if you deal with yourpresent (presumably important) topic properly than if you rush to present aquickie sketch of the remaining material. Watch the time! <p>On the other hand, beware of trying to get by with insufficient preparation.If you find yourself out of material with 30 minutes remaining in the class,you will be embarrassed and the class will be irritated. And if you don't knowtwice as much as you plan to present and if you haven't practiced yourpresentation, you may find yourself fumbling at the chalkboard and botchingyour examples. If you need help in judging how much material is appropriate,I'll be glad to discuss it with you.<p>You should encourage questions and discussion. You are not expected to be anexpert in your topic, but you should be sufficiently prepared to lead thediscussion. If there are unanswered questions, you should investigate themafter your lecture and be prepared to address them next period. If yourfollow-up discussion will take no more than 2 minutes, it can be madeverbally at the beginning of the next class meeting. If it requires longer,then prepare a brief written response to hand out to the class.<p><p>?? 快捷鍵說明
