A source computer 8 stores updated data that is to be distributed to a plurality of destination computers ( 12 to 30 ). The destination computers ( 12 to 30 ) are divided into groups sharing a common priority level ( 5, 4, 3, 2, 1 ). Each of these groups is then associated with a push update task to be executed by the source computer 8 . These push update tasks are then sequentially executed. If a particular group of destination computers exceeds a threshold size, then it may be further divided in accordance with a hierarchy of splitting rules. The push update tasks use multicasting to transfer the update data to the destination computers within their groups in a manner that reduces network traffic.
