Abstract

This paper aims to study the dynamic QoS renegotiation in a particular case, a videoconferencing application: PNSVS (Petri Net Synchronized Videoconferencing System). In the paper, we present first the QoS model (TSPN), the architecture and mechanisms used to achieve this QoS. Then we study how to handle with a synchronized switching of QoS. This leads us to a switching framework (an architecture and its protocol). Finally, we present measures proving that the architecture does not penalize the application and makes a graceful switching of QoS.
