Abstract
A circuit which includes apparatus for determining for at each node of a multi-node interconnect the highest priority data present for transfer to that node, apparatus for storing information indicating the last node from which a transfer of data occurred at each priority level, apparatus for selecting for each priority level of data available at the node the last node from which a transfer of data occurred at each priority level, apparatus for weighting data at each priority level depending on the data last chosen at that level of priority, and means for selecting from all of the data available at each node the data having both the highest priority and having been chosen least recently at that priority levels of data at that node.
