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, secure electronic commerce, 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, security, implementation techniques and user-to-user data exchange principles. The course has practical assignments on network operation, protocol design and implementation.
The course participants must have passed the following courses, or have corresponding knowledge: Algorithm and Data Structures, Computer Architectures, Operating Systems and basic knowledge about Unix and C.
Contacts with the instructors are preferably done via data communication means, i.e. via electronic mail.
The course has a World Wide Web home page: http://www.docs.uu.se/~perg/course/datakom/dv98/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.
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, made available on the course home page or distributed in class.

The course has one lab and one assignments. The assignment is:
The lab is:
The lab must be carried out at scheduled laboratory times. The main part of the Client/Server programming assignment must be carried out outside scheduled labtime. The lab and the assignment must be done in groups of two (or one) students.
Assignment reports are given directly to the course assistant
Henrik Gulbrandsen, preferebly dropped in his department mailbox
no xx, house one, level four. The lab report is given to Ernst
Nordström during the lab session or dropped in his department
mailbox, house one, level four.
The assignment and the lab will be graded and will be given bonus points if they are turned in in time. Corrected reports 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 assignment 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 1999. At that date the bonus points will also expire and the assignment will not be valid anymore. A student that fails to meet the deadline must register again for a new course instance.
The course grade is given by:
Maximum course points is 100. The points are given according to the following preliminary distribution:
The assignment and the lab are mandatory and must be of passing quality. 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 assignment is done in time.
All results will be announced in the result file, which can only be locally accessed at Polacksbacken.
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.
The lectures are divided into different categories:
Note that additional time for the Snooping lab will be scheduled later.
All lecture halls 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.
