Kursusnavn (engelsk):Distributed Systems 
Semester:Efterår 2003 
Udbydes, internet- og softwareteknologi (int) 
Omfang i ECTS:7,50 
Min. antal deltagere:
Forventet antal deltagere:50 
Maks. antal deltagere:120 
Formelle forudsætninger:Before the course the student should be able to:

  • Use world-wide-web and email.
  • Describe what a client and a server is.
  • Design, implement and test medium-sized programs in Java
    including programs using inheritance.

One way to obtain these prerequisites is by taking the course
Introductory Programming
(Grundl.ggende Programmering) followed by a course or a project at
ITU which contains programming. 
Læringsmål:After the course the student will have a basic knowledge of distributed
systems. The student will be able to:

  • Describe the fundamental principles and models used in
    designing and constructing distributed systems.
  • Describe the use of middleware, including the principles for
    distributed objects and remote invocation.
  • Describe many basic concepts in distributed systems such as
    concurrency control, transactions, multicast, replication,
    logical clocks and distributed file systems.
  • Implement distributed applications on basis of the above
    knowledge using Java Sockets and Java RMI.
Fagligt indhold:

A distributed system can be described as a collection of independent
components which are connected through a network and cooperates in
performing tasks. The components can for example be computers or mobile
phones. The network can for example be a local network in a singe building,
a network for mobile phones or the whole Internet.

In this course we will study some of the fundamental techniques used
when developing programs for distributed systems. We will do this from a
practical as well as from a theoretical point of view.
The course consists of three main parts:

  • Fundamental concepts:

    • Characterization of distributed systems and models of them.
    • Communication between processes, including Java socket programming.

  • Middelware:

    • Distributed objects and remote invocation.
    • Java RMI case-study.

  • Resource sharing and other fundamental concepts:

    • Distributed file systems.
    • Transactions and concurrency control.
    • Replication and multicast..
    • Real time clock synchronization and logical clocks.

Note that important subjects such as security and network protocols
is covered in the course Computer Security (Datasikkerhed)
and the course Network and Protocols (Netværk og protokoller)
which are good supplemental courses. 

Lectures from 13.00 to 16.00.
Exercises with instructor from 9.00 to 12.00 same day.
Mandatory exercises. 

Eksamensform og -beskrivelse:X. experimental examination form (7-scale; external exam), 13-skala, Ekstern censur

Mandatory exercises which must all be passed/approved.

Oral exam for 30 minutes (this includes time for feedback etc). The exam questions are known in advance and there is no preparation time. Grades will be given according to the 13-scale and there is external censorship. The student is not allowed to bring notes on paper. For each question the student may bring at most three slides with figures, keywords and short notes.
