Future high-speed optical networks are being designed to support huge bandwidth transmission at low cost. In this context, the integration of both wavelength division multiplexing (wdm) technology an all-optical switching (e.G., R-oadms, oxcs) is likely considered as the most suited optical network infrastructure for increasing the transport capacity in a cost-effective manner. In this new architecture, optical connections (i.E., Lightpaths) are entirely (transparently) established within the optical layer, eliminating the necessity of expensive opto/electronic (oe) conversions when switching. Furthermore, a key issue in the design of these next-generation optical networks is the introduction of intelligent and automatic control mechanisms that facilitate the dynamic provisioning of lightpaths. Such an intelligence is mainly rendered by a distributed optical control plane (i.E., Signaling and routing). A well-known implementation of the optical control plane is the generalized multi-protocol label switching (gmpls), which involves signaling, routing and resource management functions and protocols. in this dissertation we deal with intelligent and distributed routing-based schemes for dynamically provisioning and recovery lightpaths within an all-optical network through an experimental platform named adrenaline testbed. Firstly, we focus on the design of an implemented routing controller aiming at providing basic routing functionalities such as topology and resource network dissemination, reachability flooding, and path computation. The routing controller is integrated within the gmpls-based control plane developed in the adrenaline testbed at cttc laboratories. The major features and architectural aspects of the routing controller cover those recommendations and standardized protocols defined under several bodies such as ietf, itu-t, oif. next, we face up in the problem of establishing quality-enabled lightpaths within all-optical (transparent) networks consi
