Real-time network routing in the AT&T network-improved service quality at lower cost

The performance of real-time network routing (RTNR) in a dynamic class-of-service network is discussed. Three motivations for developing the RTNR network are to support multiple classes-of-service, to move towards a robust routing strategy for self-healing networks, and to simplify operations support functions. RTNR network performance results for high-day traffic loads, for peak day traffic loads, for unexpected network overloads, and for network failure are presented
