Policy Based QoS Framework

The disparity of the technologies used for managing the quality of service (DiffServ, IntServ/RSVP, 802.11e, WiMAX QoS, 802.15.4 TDMA scheduling) makes it difficult to think of the management of quality of service in heterogeneous infrastructures in terms of technologies. For this reason, a conceptual model that allows us to think about quality of service management systems independently of underlying technologies and vendors would be more adapted.

Creating an OWL Ontology with Protege: Howto Guide

Ontologies consist of three main things: Classes, Individuals (instances) and properties (relationships) between individuals. To create an ontology, one first has to created calsses.

For each class, a set of Assertions (restrictions) are defined. The assertions specify the conditions that individuals have to have in order to belong to the class. A class hierarchy is also specified by creating sub-classes (using the GUI). The Protege editor will add automatically inherited assertions from parent classes.

The flow for creating ontologies should be as follows : Create class hierarchy → Create properties → Create Assertions based on the newly created properties. This article overviews the important notions (mainly universal and existential assertions) that need to be understood for performing each of these steps using the editor Protege.
