Parallel programming of a plurality of nodes in a communication network

A communication network in a train having cars comprising:

• a plurality of first target nodes on the cars to be programmed;
• a plurality of intermediate nodes on the cars in communication network on a one to one basis with said first target nodes to be programmed;
• and
• a controller programmed to transfer in parallel to each of said intermediate nodes a first file containing a first executable program;
• and
• said intermediate nodes programming in parallel a respective first target node using said first program in said respective intermediate node.

A method of parallel programming a plurality of Neuron based nodes in a LonWorks communication network with a controller comprising:

• providing a plurality of intermediate Neuron based nodes in communication on a one to one basis with a plurality of first target Neuron based nodes to be programmed;
• transferring in parallel to each of said intermediate nodes a first file containinga first executable program;
• and
• programming in parallel each first target node using said first program in a respective intermediate node.
