Abstract
A system for executing real-time tasks, such as a multi-line modem, on a client-server network includes a control unit and multiple processing units. The control unit is implementable by the server and each processing unit is implementable by a client or by the server. For the modem, the processing units can either modulate outgoing data and demodulate incoming samples per line or can implement one stage of the modem. For the former embodiment, the control unit assigns one processing unit to each active communication between one modem application on the network and one phone line. For the latter embodiment, the control unit moves the data and samples from one stage to the next.
