Embodiments of the present invention relate to methods and apparatus for managing transaction requests in a multi-node architecture. The thin film is made by directing a monomer vapor or pyrolyzed monomer vapor towards a substrate at an angle other than perpendicular to the substrate, and polymerizing the monomer or pyrolyzed monomer on the substrate. The sensor-based techniques may include electrical and non-electrical techniques. Thus less time is used trying to fit all requests and responses into constrained choices as in previous protocols. Various approaches suggested herein facilitate production of such microelectronic devices by appropriate control of the down force of the Ge\u2014Se layer against the planarizing medium andor one or more aspects of the planarizing medium, which aspects include pH, abrasive particle size, abrasive particle hardness, weight percent of abrasive. The server computer extracts the chunks from the data frames and recombines them into the original information according to the content of the control frame.
