Abstract :
This article discusses the role of the new optical layer in terms of transport layer architecture and functional allocations. The envisaged future photonic network is identified, and the technologies needed to realize reliable communication are clarified. Network-node interface technologies, and network protection and restoration strategies are discussed in detail, since these are key to developing a network with high integrity that will be a main pillar of the future information society. Finally, applications of photonic network technologies and a network design example are presented; the IP backbone network based on optical path technologies is highlighted
