Service Negotiation Models in NGN environment
Slavica V. Boštjančič Rakas · 2012
In the paper we address the issue of provisioning E2E QoS in NGN. We describe two of the main service negotiation models and propose a functional model of the QoS negotiation interprovider via a third party (3P) agent that manages the negotiation process in a group of domains. We also present an algorithm for mapping service classes between the provider’s domains. To analyze the performance and evaluate our model and the algorithm, we develop an object-oriented application for QoS management.
