A communication network having a plurality of nodes and a controller, a plurality of intermediate nodes in communication on a one-to-one basis with the plurality of first target nodes to be programmed. A first file containing a first executable program is transferred in parallel to each of the intermediate nodes. Intermediate nodes then, in parallel, program a respective first target node. The intermediate nodes may begin programming a respective first target node upon receipt of a sufficient portion of the first file to initiate programming or may begin upon receiving the complete first file. The intermediate nodes may also have connected thereto a respective second target node and may program the second plurality of target nodes simultaneously and in parallel using either the first file already transferred or a second file containing a second executorial program transferred in parallel.
