Abstract: An improved method, system, and computer program product for efficient transmission of data to multiple network nodes is disclosed. A method for transmitting a data block over a network from a first sending node to a first set of recipient nodes, comprises, in the first sending node, a) dividing the first set of recipient nodes into a subset of selected nodes, selected according to scoring criteria associated with each recipient node, and a subset of unselected nodes, b) assigning at least one of the unselected nodes to at least one selected node according to scoring criteria associated with the respective selected nodes, c) transmitting to each selected node a packet including the data block and a list of the nodes assigned to the selected node.

Abstract: A method for improving bus performance on a bus which accommodates isochronous and asynchronous traffic and which is asynchronous traffic intensive. The method includes the step of measuring an elapsed time period between predetermined events to determine whether bus traffic is asynchronous intensive. Thereafter, a portion of the isochronous bandwidth is allocated if the measured time period meets or exceeds a predetermined amount. In this manner, large amounts of asynchronous traffic have less latency and still conform to the fairness algorithm given in the bus specification.
