Objective
Future IP-based all optical networks will require technologies to enable packet routing at Terabit/s bitrates. All-optical label swapping (AOLS) is a type of optical packet switching that is intended to solve the potential mismatch between fibre capacity and router packet forwarding capacity. To date packet label processing has been carried out at the electrical domain (for example, IST-STOLAS or IST-LABELS).
However, in order to achieve full transparency at the optical node it is necessary to perform this functionality at the optical domain. Likewise, the node optical layer needs to implement the required "intelligence" to look up the routing table and forwarding the packets. LASAGNE project aims at studying, proposing and validating the use of all-optical logic gates and optical flip-flops based on commercially available technologies to implement the required functionalities at the metro network nodes in AOLS networks. The optical gates are implemented using the same key building block: Mach-Zehnder interferometers (MZIs) incorporating semiconductor optical amplifiers (SOAs), which results in a really flexible and scalable approach in terms of manufacturing.
A functional photonic router prototype incorporating all-optical label swapping and wavelength conversion will be integrated using optical logic gates and optical flip-flops. This photonic router is featured as modular, scalable, and with potential of large system integration, what is achieved employing the same key building block in all in-node functionalities (SOA-based MZIs). The definition of the architecture of the AOLS node should be consistent with the proposed network scenario and protocols used. Both technical and economic implications of the proposed AOLS node structure and functionalities over the existing GMPLS-based services or protocols, and future European optical networks will be assessed. Moreover, intermediate solutions between a circuit-switched network and an AOLS network will be considered.
