Abstract:
A method for transmitting a data block over a network from a first sending node to a first set of recipient nodes, comprising:in the first sending node: 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; assigning at least one of the unselected nodes to at least one selected node according to scoring criteria associated with the respective selected nodes; transmitting to each selected node a packet having a payload including the data block and a first list of the nodes assigned to the selected node, the list dynamically associating the selected node with the unselected nodes for the transmission of the data block to the unselected nodes; in at least one recipient node: receiving from the first sending node the packet having a payload including the data block and the first list of assigned nodes; dividing the first list of assigned nodes into a subset of selected assigned nodes, selected according to scoring criteria associated with each assigned node, and a subset of unselected assigned nodes; reassigning each of the unselected assigned nodes to at least one selected assigned node according to the scoring criteria associated with the respective selected assigned nodes; and transmitting to each selected assigned node a packet having a payload including the data block and a list of the nodes reassigned to the selected assigned node, the list dynamically associating the selected node with the unselected nodes for the transmission of the data block to the unselected nodes.
