The project aims at proposing an evolutionary methodology for the design and management of optical networks in order to support the migration from the current static assignment and routing techniques to adaptive, dynamic techniques based on IP-centric control as soon as new generation equipment becomes available.
The specific objectives of our research project are:
The resulting static design methodology will produce scalable architectures that will adapt to larger numbers of wavelengths and enable migration towards an efficient dynamic design and management of optical networks. Traffic engineering schemes to deal with fine granularity at sub-wavelength resolution will be developed mainly exploiting OTDM. The network design will also consider the resilience property of the topology and traffic uncertainty.
New techniques will be proposed for the design and management of dynamic optical networks based on IP-centric control, in particular dealing with fast dynamic lightpath establishment, protection and fault restoration. Distributed "intelligent" algorithms will be considered, in which some parameters will be adapted in an online manner through feedback from the previous history. Finally, new switching architectures will be evaluated, capable of realizing the proposed protocols.
