Abstract: A coordinated multi-cast content distribution process is used to distribute content, e.g., files, from a source node of a network to target nodes of the network. A minimum spanning tree is identified for the network based on costs of edges connecting the nodes. The minimum spanning tree includes the source node and all target nodes; the minimum spanning tree distinguishes leaf target nodes from non-leaf target nodes. Content parts are moved along the spanning tree in an iterative process in which, for each iteration, the highest-cost leaf nodes are identified and content parts are moved toward the identified leaf nodes. This process reduces avoids network congestion and reduces the total bandwidth consumption required to supply the content to all target nodes.
