Abstract

A method and system for data collection and processing, such as for collection and processing of data read by a utility meter, generates a message having header information, a first packet having data of a first type, and a second packet having data of a second type. Each packet includes header information that identifies the data type of the packet The system also includes a head-end subsystem with multiple processors, each for processing a distinct data type. A message organizer component delegates each of the packets of data to the appropriate packet processor.
