A method and apparatus is disclosed herein for information delivery with network coding over time-varying network topologies. The data is converted to a frequency spectrum which is analyzed to create a fault signature having fault attributes relating to various fault conditions associated with the pump. , and the recovery points of said operator. A record of the mismatches that have been encountered, the design elements that are involved in each mismatch, and what action where taken to repair the mismatch is kept and maintained.
