A spark plug is provided with: a central electrode; a ground electrode forming a spark discharge gap with the center electrode; and a chip welded to at least one of the electrodes. The methods include forming openings in a high-density area and a high-speed area, and forming a metallization layer simultaneously into the high-density area and the high-speed area. The routing tables used to route the content through the network are derived by aggregating information about either content consumers or content producers into ontological trees.
