Provision of Broadband Video Conference via IN and B-ISDN Integration: Architectural and Modelling Issues
Francesca Cuomo, Marco Listanti, F. Pozzi · 1997
This paper deals with the integration between the Intelligent Network (IN) and the B-ISDN for the support of an advanced multimedia service, i.e. the Broadband Video Conference (B-VC). The focus of the paper is the proposal of a new role of the IN that, in a closed interaction with the B-ISDN, furnishes control functionality to handle complex service configuration. In order to assign such a role, we distinguish different levels of control into the IN architecture and we propose functional models able to represent, at each level, a specific service view, suitable to th IN, and cooperating for a global service provisioning. Some different options for an IN/B-ISDN interaction are discussed; in particular, the architectural aspects of a solution distributing the IN control logic between the Service Control Function (SCF) and the Service Switching Function (SSF) are described in details. Finally we consider an actual multimedia service, the Broadband Video Conference, supported with the proposed approach, and we analyse the relevant performance behaviour.
