Abstract

Methods for prioritizing load management messages on IP-based networks utilizing an Active Load Directory and IP capable two-way gateway. The messages being received from, or sent to, the ISP through the gateway contain a blend of regulated and unregulated data. The regulated data is high-priority utility load management data such as, equipment status and load control instructions. The unregulated data consists of Internet messages such as email and web site data. These methods process all regulatory data before unregulated data within strict time limits, providing the greatest possible load management control and energy savings. The methods emulate dedicated network processor memory in a manner that permits the rules for prioritizing, scheduling, and routing to remain the same across both hardware and software implementations.
