Abstract: | In this paper, we propose an agent architecture to improve flexibility of a videoconference system with strategy-centric adaptive
QoS (Quality of Service) control mechanism. The proposed architecture realizes more flexibility by changing their QoS control
strategies dynamically. To switch the strategies, system considers the properties of problems occurred on QoS and status of
problem solving process. This architecture is introduced as a part of knowledge base of agent that deals with cooperation
between software module of videoconference systems. We have implemented the mechanism, and our prototype system shows its
capability of flexible problem solving against the QoS degradation, along with other possible problems within the given time
limitation. Thus we confirmed that the proposed architecture can improve its flexibility of a videoconference system compared
to traditional systems.
