Abstract: A novel method and system for an LCR engine, herein referred to as a Dynamic Intelligent Routing Engine (DIRE) is disclosed that optimizes in real time the routing of data on a communication network. The method and system includes novel hardware architecture and software where routing queries from telecommunication switching equipment is sent to the DIRE. The DIRE responds to the queries by providing an optimized list of termination vendors. The DIRE provides real time or near real time solutions by addressing issues pertaining to mixed and fixed costs routes, control margins, weighted routing parameters, quality routing and other selected information that may affect routing costs.
