Fault Tolerance Seminar (2014)
Prof. Dr. Andreas Polze
In distributed software systems, fault tolerance denotes the ability to continue operating in the
presence of component failures.
The importance of fault tolerance has grown steadily with the increasing complexity and distribution of
Various forms of redundancy in space and time can be employed to build highly available or reliable
software. In order to make a software system robust against many faults, a detailed understanding of its
distributed architecture, the component interfaces, and its probabilistic failure behaviour is necessary.
This seminar provides an overview of how fault tolerance, as a central dependability requirement, is achieved in modern software systems.
Topics covered in the seminar include distributed systems theory, patterns for fault tolerance, as well as fault tolerance case studies at the operating systems and distributed application levels.
Extent: 2 semester hours (3 graded credit points)
Dates: Thursday, 13.30 - 15.00
Identifiers (SO2010): SAMT, OSISThe seminar focusses on literature review. Participants are required to read fundamental scientific publications on fault tolerance in distributed systems, and present them to their fellow students.
- Each participant is expected to give a 30-45 minute presentation on a topic.
- Presentation slides should be discussed with a supervisor one week prior to the presentation date.
- At the end of the seminar, we plan to assemble a technical report about your seminar topics.
