SANGN: A New Service Oriented Architecture for Provisioning of NGN Scalable Multimedia Services

摘要

The introduction of Next Generation Networks (NGN) has changed significantly the network service model. Vertical structures that are designed to each type of access have been replaced by horizontal structures. However, the service architecture has to be rebuilt to support the required agility within the horizontal structures. Our proposal, named SANGN, is based on a full integration of Open Services Gateway Initiative (OSGi) with Java Agent DEvelopment (JADE) framework for providing multimedia services of IP Multimedia Subsystem (IMS). We have introduced a Televote service as a use case in order to validate the SANGN architecture ensuring the massive scalability of these services to meet the stringent multimedia requirements. Our implementation is able to adapt with a high dynamic load of the system, making use of a minimal set of computational resources seamlessly for the clients, providing IMS core components in the network infrastructure.
