Technology-trial of dynamic traffic routing with 5 minute updates

DR5 (dynamic routing with 5-minute updates) is a routing scheme for telephone traffic in which traffic measurements provided by the switches at 5-min intervals are used to define the routing to be followed for the next 5 min. A successful technology-trial of DR5 was conducted in a five-node subnetwork of 1A-ESS switches. The authors describe the DR5 algorithm, the architecture used for its implementation in the technology trial, and the main results of the trial. They also provide the results of economic studies on the potential benefits of DR5 deployment, and they discuss the possible future implementation of dynamic routing as part of the advanced intelligent network (AIN) architecture. The work described considers dynamic routing in the circuit-switched voice network
