Configurable Multi-agent System for Qos Control in Watm

This paper introduces a configurable multi-agents architecture for QoS control in WATM. The ultimate aim of the proposed architecture is to provide a selfregulating network congestion control management by means of global network state awareness and agents interactions. The agents dynamically manage the buffer space at the level of a switch and interact to reduce the cell loss ratio while guaranteeing a bounded transit delay. We particularly address video transmission over UBR services using a per-VP queuing approach and an adaptive cell discarding congestion control scheme. Furthermore, a dynamic reconfiguration of the agents is performed during handoffs in order to continue meeting user end-to-end QoS requirements.
