The SEAN Architecture

The SEAN architecture is composed of four parts - the signaling daemons (SD and SIM), the application programming interface (API), the address registration daemon (ILMID), and the driver (DRIVER). Figure  2.1 shows several SEAN applications communicating with one another on an ATM network through their APIs and signaling Daemons.
