Method of information transfer in distributed system involves first process initiating link set-up in permitted direction, enabling second process to transmit spontaneous information in response

摘要

The method involves using a communications channel between computing processes which is limited with respect to the direction of initiation of an information exchange in that the initiation can only take place in one direction. This limitation is overcome by a first process initiating a link set-up in the permitted direction, enabling the second process to transmit spontaneous information in response and the first process interpreting the spontaneous response as a link set-up that would not be possible with the prevailing limitation.
