Description of a Functional Signaling Architecture for Broadband Networks

This paper presents a modular signaling architecture and protocols to control calls, connections, and services in B-ISDN. The architecture is based on servers placed in the network that provide various network and service specific functions. The services, and hence servers, are implemented and operate independently of one another. All service coordination is managed by a call server. This allows services to be introduced in a modular fashion. The separation of network transport from services is emphasized. The servers and users maintain a client-server relationship. Therefore, ROSE-based protocols may be used to efficiently carry signaling information required to request services.
