A method and apparatus for managing a data structure for multi-processor access are described. The apparatus includes a storing unit that stores arrangement information of the OADM nodes and operating wavelength information of optical signals transmitted by the nodes. Each of the interfaces transmits the image data at an identical transmission rate irrespective of the number of the transmission lanes to be used. The lighter combustible, pollutants effected in the first separation are piped to the Installation’s engine air intake for re-combustion, thereby reducing the Installation’s Methane pollution and improving its fuel economy.
