The DREAMS project developed an optical DWDM network with ROADM nodes. GMPLS software is used for the network control plane to reconfigure optical nodes automatically. In addition, ARGIA software will be used in DREAMS, allowing to users to represent virtually the network resources (links, nodes, ports, …) that are accessible as web services. Through these virtualized resources, a user can create a virtual private network aligned to the requirements of the service they need. The network management system will be controlled by an unified NMS.

  • Development and construction of a ROADM node: This node allows switching of optical channels through the ports of extraction (drop) and insertion (add). Node must be "colorless" (able to operate with any set of optical channels).
  • GMPLS software development: This software consists of a series of components to be developed by adapting the existing components in the ADRENALINE testbed from CTTC.
  • Management software development (NMS): The management is based on a centralized NMS system that will interact with the elements of the control plane (GMPLS and ARGIA) and of the transport plan (ROADM nodes). The system will include management capabilities, logical and physical inventory, service provisioning, alarm management, management measures, and usage measures. It will develop a web GUI and a standard interface for generic systems OSS / BSS.
  • Adaptation of ARGIA software: With this software users can partition the network resources (for example a user may be assigned one or more ports of ROADM) so that multiple users can operate independently on their allocated resources without interfering with those from others. An important task in this project is the adaptation of ROADM nodes ARGIA implementing a new web service. In addition a commercial quality GUI should be created.
  • All features are integrated to form a 3-node optical network ring and 2 unidirectional fibers (work and protection).

With this project we come a little closer to how they should be the telecommunications networks of the future: flexible, dynamic, intelligent and reconfigurable. With the development of a GMPLS control plane we are providing intelligence and automation to the network, enabling optical connections dynamically and with the QoS required, plus dynamic protection and restoration of optical channels. This brings us to the implementation of optical networks with lower costs of maintenance and management. The use of ARGIA in optical networks will be important in specific networks (research, academic, ...).
