Unlike IntServ where resource reservation and admission control is per-flow based using RSVP, DiffServ supports aggregated traffic classes to provide various QoS to different classes of traffics. However, it is possible to lead to serious QoS violations without a QoS management support. Therefore, a QoS management system that can manage differentiated QoS provisioning is required. This paper proposes and implements a policy-based QoS management platform for differentiated services networks, which specifies QoS policies to guarantee dynamic QoS requirements. High-level QoS policies are represented as valid XML documents and are mapped into EJB beans of the EJB-based policy server of the platform. The policy distribution and the QoS monitoring are processed using SNMP.
