Sažetak
A key challenge for the next generation network (NGN) is securing Quality of Service (QoS) support for personalized and advanced multimedia services. In this paper we present a comprehensive and generic SErvice-Level End-to-end QoS negoTiation and adaptation (SELEQT) framework. The framework comprises four conceptual models addressing and relating the following aspects: the actors involved in QoS negotiation (Business Model) ; specification of the parameters that impact the QoS negotiation process (Data Specification Model) ; the identification of dynamic adaptation-triggering events that lead to QoS renegotiation and adaptation (Adaptation Event Model) ; and the process of matching and coordinating QoS parameters specified and signaled by involved actors (Negotiation Model). Framework applicability is illustrated using an example multimedia service scenario.
