ABSTRACT:
An apparatus and method for communicating information between a computer and a plurality of peripherals along a plurality of communication channels is disclosed. The computer and peripherals are connected in a succession of stages (cascaded), in a tree-like (hierarchical) communication network configuration. Peripherals in the network include an associated communication unit which is responsible for transmitting and/or receiving data communicated on a communication channel. The communication unit facilitates the transfer of data to, and the receipt of data from, the unit's parent, and also facilitates the transfer of data to, and the receipt of data from, any child units. In the invented method, each communication unit, in parallel, composes those individual messages received from child units into a single composite message and transmits the composite message to the communication unit's parent. The parent, in turn, composes those individual or composite messages it has received into a single composite message and transmits the contents to its parent. This continues until a single composite message is transmitted to the computer for processing. The computer decomposes a composite message into its constituent individual messages and processes individual messages. The computer can also transmit messages to peripherals in a reciprocal manner, that is, by composing a single composite message to be transmitted to the first stage communication unit and thereafter decomposed and distributed to designated nodes within the network.
