Abstract:
The evolution of next generation network raises the issue of exploiting customizable services for a nomadic user within the environment of heterogeneity and mobility. In this context, the E2E QoS (Quality of Service) always remains as a challenge. In fact, the E2E supposes that apart the network resource, the service should be taken into account as an important resource, in the form of service component, i.e., we should also provision and monitor the service resource and verify the conformation to the QoS contract. In this paper, we propose a “dynamic user oriented end-to-end QoS signaling” for the service delivery in order to provision and dynamically negotiate the different services in the NGN environment. This end-to-end signaling extends to process the service delivery to maintain QoS continuity. The related sequence diagrams are defined and a demonstration is implemented with the purpose of presenting the feasibility of our proposals.
