Knowledge Goals
  • Know definitions of distributed systems, as well
    as the fundamental design challenges of such
    systems
  • Know some of the models which can be used to
    describe distributed systems, as well as their
    leading areas of use

9
Knowledge Goals
  • Get the picture how networks are connected to
    each other through internetworking technologies
  • Understand the differences between basic
    transport protocols TCP and UDP

10
Knowledge Goals
  • Learn the application programming interface for
    Internet protocols
  • Know the basic problems of inter-process
    communication and data transfer between systems
  • Know how distributed component-based
    communication is realized using Remote Procedure
    Call and Java Remote Method Invocation

11
Knowledge Goals
  • Know the fundamentals of peer-to-peer
    communication and applicability of peer-to-peer
    models for different problem domains
  • Learn one example of realizing peer-to-peer
    systems

12
Knowledge Goals
  • Understand the overall structure and formation of
    many distributed systems
  • Learn some examples of how distributed systems
    research can be carried out
  • Get an overview of the different aspects related
    to distributed systems

13
Passing Requirements
  • There is a mandatory part Distributed Systems
    special questions for everyone and three
    alternative ways for passing the course
  • Examination,
  • Literature review or
  • Programming work
  • You can select the one which is most suitable for
    you

14
Distributed Systems Special Questions
  • Set of questions that needs to be answered at
    free time
  • Covers different areas of distributed systems
  • Graded as passed/not passed
  • If some questions have not been passed then those
    questions not passed needs to be answered again

15
Examination
  • Normal examination with 4questions
  • 6 points per question withmaximum of 24 points
  • Standard rating criteriasused in embedded
    systemsand telecommunicationscourses
  • Examples of earlierexaminations can be
    foundfrom the course web page
  • http//www.mit.jyu.fi/cheesefactory/TIES427.htm

16
Literature Review
  • Literature review is a scientific oriented
    learning task
  • Knowledge can be accessed using digital libraries
    e.g., ieeexplore.ieee.org

17
Literature Review
  • The aim is to
  • identify and extract a certain distributed
    systems related research problem from research
    literature using about 5 scientific articles
  • review the approaches authors have used for
    solving the problem
  • analyze, reflect and criticize the solutions used
  • write a report
  • pass the peer review process conducted by the
    lecturer

Literature Review
  • Some examples of distributed systems research
    problems
  • Distributed objects, distributed event
    notification, external data representation and
    serialization, security of mobile code, context
    awareness, dynamic address allocation for mobile
    devices, dynamic P2P network models, P2P grids,
    P2P file systems, encrypted P2P networks,
    resource discovery problem definitions,
    computationally intelligent methods in
    distributed systems, delay tolerant networks
  • The only requirement for the problem is that it
    is related to distributed systems

19
Literature Review
  • The grading of literature review is based on
  • How clearly the problem has been extracted from
    literature
  • How difficult the problem is
  • How well the selected articles have been
    reflected to each other (fusion and creation of
    new knowledge)
  • Examples of earlier literature reviews made on
    the course can be found from the course web page
    http//www.mit.jyu.fi/cheesefactory/TIES427.htm

20
Programming Work
  • Programming work is aimed for people that might
    have own distributed system development project
  • Typically involves e.g. socket programming,
    problems of concurrent behavior, multiple users
    or/and development of a protocol
  • Helps to learn more thoroughly some of the
    problems discussed in the course

21
Programming Work
  • As a passing requirement a documented description
    of the distributed system and a quantitative or
    qualitative analysis of the produced system is
    needed
  • Quantitative analysis can be made by measuring
    the behavior of the system
  • Qualitative analysis can be made by
    characterizing the behavior of the system and
    comparing the system to other systems
  • Examples of earlier programming works made in the
    course can be found from the course web page
