In this paper, we present an overall architecture to integrate SIP-based session management with scalable QoS features and AAA functionality. The QoS features include a bandwidth reservation in the access network based on the Next Steps in Signaling (NSIS) architecture. Furthermore, we employ the DiffServ compliant Priority Promotion Scheme (PPS) which is a(More)
One of the key requirements of today's and future network infrastructures is to provide Quality of Service (QoS) support for end-to-end applications, by distinguishing the application flows and properly handling them in network nodes. As an important component to achieve Internet QoS, explicit signaling schemes for resource reservation have been proposed,(More)
