Since the structure is a "tree" the "parent" concentrates the signalling from how many "child" processors.

Will the signalling remain in the serial format or will it be parallel.

Is the algorithm "store and forward" or is their a "real time" exchange.

Does the parent exchange with another processing system or does it perform activity based upon input signalling.

Do "child" processors retain their data or do they depend upon the "parent" to store it.
