A review and survey of routing techniques in transparent core optical networks: Evolution, perspectives and frontiers

In this survey, we presents a framework that proposes a guidelines and recommendation for the Routing Techniques perspectives in optical networks. Several subject are discussed in detail in this paper. A first important topic is the fundamental of Optical Routing techniques for network planning and optimization has recently attracted intensive research interest particularly in the area of intelligent control plane. A second important issues is the routing problem in networks with static, incremental and dynamic. In addition, we investigate several routing techniques by comparing in term of their operation, characteristics and mechanisms. Finally, this survey contributes to appropriate knowledge and challenges in legacy optical networks and towards future research development.
