SEAN for Modeling and Simulating ATM Signaling

SEAN (signaling entity for ATM networks) is freely distributed, object-oriented, extensible software for research and development in host ATM signaling. SEAN software is object-oriented and can be used for simulation, experimentation, and operation. SEAN includes a complete source-level release of the host native ATM protocol stack and implements the ATM User Network Interface, compliant to the ITU Q.2931 specification for point-to-point calls, the ITU Q.2971 extension for point-to-multipoint calls, and the ATM Forum extension UNI-4.0 for leaf-initiated join calls. SEAN also includes software that models and simulates an ATM switch with an arbitrary number of ports performing the signaling functions. SEAN provides APIs to the programmers writing application programs that require ATM signaling. Developers can easily modify and extend SEAN, using the framework library released together.
