Dynamic network evolution achieves network performance improvement and cost reduction by taking advantage of new advanced technologies being introduced into the network to achieve greater network flexibility and efficiency. The author describes the evolution of dynamic networks, with examples drawn from the AT&T DNHR network deployed in the '80s and RTNR network deployed in the '90s. Dynamic traffic routing implements an integrated class-of-service routing feature for extending dynamic routing to emerging services, and provides a self-healing network capability to ensure a network-wide path selection and immediate adaptation to failure. Dynamic traffic routing brings benefits to customers in terms of new service flexibility and improved service quality and reliability, at reduced cost
