Introducing SEAN: Signaling entity for ATM networks

SEAN is freely distributed, object-oriented, extensible software for research and development in host ATM signaling. 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 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. This paper briefly describes essential parts of SEAN's architecture and guides the users and protocol developers.
