Abstract

In a communication technique called "outband signalling", a digital transmission link (path/bus/wire(s)/fiber(s)), used for transferring blocks of data, is complemented by a separate, additional link on which related control information is transferred. This general technique can be effectively adapted to the I/O channel of a data processing system to provide advantages over alternative designs.
