Data Communication distans Spring 97

Introduction

The subject data communication include architectures, design methods and implementation techniques for the exchange of data 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 Algorithm and Data Structures, Computer Architectures, Operating Systems and basic knowledge about Unix and C.

Course home page and news

The course has a World Wide Web home page: http://www.docs.uu.se/~perg/course/datakom/distans97/index.swe.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.

Assignments

The course has the following assignment:

1. The Sliding Window Protocol in SDT
   Questions answered by Ernst Nordström and Jochen Schiller

The assignments are to be done in groups of two (or one) students at scheduled laboratory times.

Lab reports are given directly to the course assistant Ernst Nordström, preferebly dropped in his department mailbox , house one, level four. The assignments 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 2, 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 also 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 May 31, 1997, 9-15, at Polacksbacken).
2. Mandatory assignment.
   (The turned in assignments must be of passing quality).

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

• At most 15 points for the Sliding Window assignment. Deadline for bonus is 970531, 1700.
• At least 85 points for the written exam.

Preliminary, the course grade G requires at least 55 points, grade VG at least 70 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. Therefore 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 assignment (EN)

All lecture 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 Ångströmslaboratoriet. The second digit represents the level.

Reading directions

The following chapters in Tanenbaum. Other literature should be read completely or otherwise according to recommendations in class.
