Abstract
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.
The present research has been conducted by the Research Grant of Kwangwoon University in 2004.
