Next-generation networks

Dramatic changes in technology, network services, and regulation are driving the rapid definition and implementation of new network architectures and elements. This paper discusses the forces that are moving today's networks toward converged, next-generation networks. It also provides a multiservice, high-performance, and highly reliable next-generation network architecture. This architecture serves as a framework for placing the papers in this issue in context. Together these papers provide a view of Lucent Technologies' Network Vision with a focus on packet networking; including network architecture and planning, intelligent packet switching, packet voice, quality of service, virtual private networks, and network and service management.
