Abstract

The experimental ATM network services environment (EXPANSE) prototype provides an experimental testbed for multimedia multiparty telecommunications services over heterogeneous communications networks. The EXPANSE software architecture supports the functional separation of call and connection control. At the call control layer an object‐oriented, transaction‐based call model provides for the co‐ordination of the negotiations among users for the establishment, modification and disconnection of telecommunications services. The connection control layer provides an object‐oriented protocol for the dynamic establishment, modification and release of network connections which include the control and allocation of network resources required for multimedia multiparty services.The EXPANSE software includes an application programming interface (API) to the signalling protocol at the call control level. The API provides a uniform and powerful interface to the call model and allows different applications to co‐ordinate the control of local resources and session state.
