This paper investigates an approach to enabling dynamic reactive quality-of-service (QoS) management for IP networks. We use the information collected from monitoring traffic flows combined with middleware for setting network element configurations to differentiate the service given to traffic. We report on experiences of implementing the QoS management system using XORP (eXtensible Open Router Platform) and Click, the open source software router. The performance evaluation in terms of packet loss, dynamic behaviour of QoS configuration and time to re-configure the XORP+Click router is presented.
