• Replication

The quality of a service offered in a distributed system such as the World-Wide Web often determines the chances of its sale. In this respect, an electronic service differs only marginally from a "physical" - or in-store - service. In distributed systems, however, other qualities may be indispensable: For example, real-time behaviour, runtime availability, waiting period or access costs may be important from the customer side. On the other hand, the service provider may be interested in the best possible scalability or a low storage space requirement for the service.

• Basic knowledge of operating system concepts and distributed systems
• Knowledge of a higher programming language (C, C++, Java)

The subject of the work is the identification of meaningful "quality of service" categories for services in electronic networks from the perspective of 1) the network administrator, 2) the service provider (server and owner) and 3) the customer. In addition, a "catalogue of measures" for the realisation of the identified quality requirements is to be developed. Exemplary examinations of typical services in the World-Wide Web or a company's own network, combined with improvement approaches for services recognised as inadequate, are also the aim of the work.

The work contains practical elements.
