Polus Framework

The three main parts of the Polus framework are:

Modeling of information: The model describes how actions such as prefetching, replication, etc are represented in the system.

Generation of the knowledge base: How rule-of-thumb specifications and learning are used in conjunction to generate the details of the information model.

Reasoning: During the detection of a QoS violation, the reasoning engine decides which action to invoke using the information in the knowledge base. The management semantics of the reasoning engine are expressed using first-order predicate calculus.
