Course Information

Data Communication TF ht96

    1. Introduction

    The subject data communication include architectures, design methods and implementation techniques for the exchange of data in between computers in computer networks.

    The importance of computer networks has increased dramatically with the recent wide spread usage of the Internet and the World Wide Web. Knowledge of data communication is necessary for the design of personal telecommunication systems, remote data base systems, distributed systems and other cooperating computer systems.

    The objective with this course is to introduce, study and to discuss the main issues in data communication. It will include layered communication architectures, transmission techniques, protocol design, network organization, implementation techniques and user-to-user data exchange principles. The course has practical assignments on protocol design and implementation.

    Prerequisites

    The course participants must have passed the following courses, or have corresponding knowledge to Computer Architectures, Operating Systems and basic knowledge about Unix and C.

    Instructors

    Contact with the teachers is preferably done via data communication means, ie via electronic mail.

    Course home page and news

    The course has a World Wide Web home page: http://www.docs.uu.se/~perg/course/datakom/tf96/index.eng.html. News, some lectures notes, assignments, result announcement and other course related information will be announced on the page besides ordinary class room announcements. It is assumed that all students regularly are reading this page. Results from exams and assignments can only be reached from computers at Polacksbacken.

    Text book and other literature

    Recommended reference literature

    Additional course material

    The text book will be complemented with additional papers, lecture notes, assignments etc. This material will either be for sale by Magnus Berggren, room 1403, or distributed in class. A course binder (kurspärm) with one copy of all the material will be available at the DVP expedition (room 1406) for copying.

    Assignments

    The course has the following assignments:

      1. The Alternating Bit Protocol in SDT
      2. Client/Server programming in Unix

    The assignments are done in groups of two (or one) students at scheduled laboratory times. The main part of the Client/Server programming assignment must be carried out outside scheduled time.

    Lab reports are given directly to the course assistant Bjorn Knutsson, preferebly dropped in his department mailbox, house one, level four. The assignment will be graded and will be given bonus points if they are turned in in time. Corrected assignments can be found outside the DVP expedition at level 4, house 1 and the grade can be found in the in the result file.

    Deadlines for the assignments can be found below. Any changes in deadlines are announced on the home page. Assignments turned in later will be corrected and graded sometime before 31/8 1997. At that date the bonus points will expire and the assignments will not be valid anymore. A student that fails to meet the deadline must register again for a new course instance.

    Examination

    The course grade is given by:

    1. Written exam. (Ordinary exam is October 18, 1996.).
    2. Mandatory assignments (The turned in assignments must be of passing quality).

    Maximum course points is 100. The points are given according to the following preliminary distribution:

    Preliminary, the course grade 3 requires at least 55 points, grade 4 at least 65 points and for grade 5, 75 points or more. Note that it is difficult to pass the course unless the assignments are done in time.

    Result announcements

    All results will be announced in the result file, which can only be locally accessed at Polacksbacken.

    Cheating

    At other instances of this course a few students have been cheating with mandatory assignments. Because of this we want to stress that these assignments must be solved individually or in groups of two students. All participants in a group are assumed to be able to present and explain the groups solutions to the instructors. The assignments represents an important part of the course and we have earlier reported all suspected cheatings to rector magnificus. The Högskoleförordningen is clear on this point:

    Paragraf 1: Disciplinär åtgärd får vidtas mot student som ... med otillåtna hjälpmedel eller på annat sätt försöker vilseleda vid prov eller när studieprestation ska bedömas.

    ...

    Paragraf 9: Grundad misstanke om sådan förseelse som anges i Paragraf 1 skall skyndsamt anmälas till rektor.


    Preliminary lecture plan

    The lectures are divided into different categories:

      (F) Lectures (PG, JS, EM)
      (U) Preparation for the assignments (BK)

    All class rooms are at Polacksbacken. The first digit represents the building, for example 1=Infanteristen/DoCS, 2=Matematikum, 6=Rullan and 8=Sjukan/Reglerteknik. Room numbers 2001-2005 refer to Angstromslaboratoriet. The second digit represents the level.
