Assignments for presentations:

The articles and links here represent starting points for a presentation. Some articles are a subject in themselves and the presentation will focus on just that article. Other articles represent a system and are more an overview. Such an article is usually more on the surface (also: easier to read) and the presentation requires that you also look at related articles. Therefore, the following list is based on the subject that the presentation should have.

Make sure to use an example for these systems, preferably the same when you compare two.  Demonstrate and explain the following perspectives: the programmers’ (what he does, which concepts she sees and uses), the end-users’, the interactions between system components in response to the actions in the example.

1.      Security, the 802.11 case [WEP] (1 group)

a.      The paper by Borisov, Goldberg and Wagner describing some insecurity problems. Use the paper to obtain pointers to describe WEP security, including the architecture. The IEEE 802.11i standard describes solutions. The book by Coulouris c.s. describes weakness in the entire architecture.

2.      The Grid, project Globus (1 group)


b.      Papers on this site at particularly

c.      What is the grid: and the Grid anatomy

d.      Select a some specific issue, like separation of computation and data scheduling

3.      Peer to peer systems, 2 groups can work on this, synchronize your work and presentations.

a.      What is the essence of peer2peer? Take it as a challenge to determine a point of view in this such that, after your definition, we can classify systems as being p2p or not. Pay attention to the architecture, the algorithms, the addressed issues, the goals.

b.      The basic article on the Chord system at MIT, the web site.

c.      Microsoft Research’s Pastry and Squirrel

d.      File sharing with Bittorrent, Gnutella, Freenet (look at the paper section).

4.      Systems based on distributed objects, DCOM and CORBA – 2 groups can work on this but if so, discuss and distribute the work together. For this it may be useful to first plan the rough targets of the presentation and subsequently search for the information. Relate it to the ‘concepts’.

a.      Starting point is the book, chapter 9 – use references herein.

b.      Microsofts DCOM, a fairly dated description of it, search the web, some more info on (D)COM

c.      OMG’s CORBA

d.      A comparison of DCOM and CORBA

5.     Naming and naming systems (1 group)

a.      Starting point is the book, the chapter on naming. Pay particular attention to the problem(s) that must be solved with such a system.

b.      Example systems: The domain name service (see e.g. the book), Intentional naming system, P2P Intential naming system.

c.      Address also location or mobility issues (see the book again).

6.      Systems based on coordination – 2 groups can work on this, distribute the work together

a.      Starting point is the book, chapter 12 – may use references herein to select one additional article. Make sure that you pay attention to the scope of these systems.

b.      Coordination is usually focussed on connecting distributed services; the Berkeley Service Discovery System addresses advertisement and discovery. It is part of the Ninja Project.

c.      Other systems are TIBCO’s TIB/rendezvouz (not so much referenced) and Sun’s Jini; related is Microsoft’s Universal Plug ‘n Play at

7.      Systematic introduction of fault tolerance (1 group, 2 groups are allowed given a good work distribution)

a.      Starting point is the book.

b.      Byzantine Fault tolerant systems at

c.      Description of approach, e.g., :

d.      New contribution in the Base approach and system (library),

8.      Security (1 group)

a.      MIT’s Kerberos system; give the basic ideas, assumptions, purpose. Show the system architecture and relate to the notions discussed in the lectures.

9.       (Multi-) agent systems (1 group) – this topic is not available this year unless you come with a good proposal for new cases/literature, beyond the material below.

a.      A nice starting point:

b.      An overview (not too recent though):

c.      The foundation for intelligent physical agents: works on standardization and coherence

d.      The madkit system at and articles

e.      Madkit architecture overview: Articles/madkit-overview.pdf and dealing with heterogeneity: Articles/madkit-heterogeneity.pdf. 

f.       Pay particular attention to what these systems are really good for, what their contribution is in contrast with what we already have. Also, draw lines to other systems (peer2peer, Corba etc.) if you see fit.
