Abstract:
A computer telephony server for simultaneously implementing a plurality of messaging applications is provided. The server includes a processor, a memory and a plurality of slots connected to the processor through a high-speed bus, each of the plurality of slots being adapted to receive an interface card for connecting the server to an external resource. A plurality of primary sessions are provided, each of which have a first thread of execution on the processor and control a first subset of the memory and at least one external resource. A plurality of secondary sessions, each corresponding to one of the primary sessions, is also provided. Each secondary session has a second thread of execution on the processor and controls a second subset of the memory. The primary session delegates a set of system resources to its corresponding secondary session and monitors the secondary session's behavior. In addition, the primary session operates to recover the set of system resources delegated to the secondary session upon the termination of the secondary session.
