Mission

Wordle: Wikiona

Research in optical networking technologies is performed at Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) within its Optical Networking Area (ONA), whose goal is the evolution of telecommunication systems towards intelligent, dynamically reconfigurable all-optical transport networks. Currently, research work is based on enhancing the intelligence, efficiency, robustness, capacity and cost-effectiveness of Wavelength-Switched Optical Networks (WSON) and Connection-oriented Ethernet (COE) through Generalized Multiprotocol Label Switching/Path Computation Element (GMPLS/PCE) and Optical Orthogonal frequency-division multiplexing (Optical OFDM) technologies. This research goal is approached in two generic research lines that encompass several specific scientific and technological objectives:

  • The Optical network control and service management research line addresses the service-aware network architectures, protocols and traffic engineering algorithms (provisioning, protection and restoration strategies) in order to provide effective quality-enabled optical services for multi-layer and multi-domain networks.
  • The Optical transmission and systems research line focuses on optical transmission technologies and advanced performance monitoring techniques for high-capacity all-optical (transparent) transport networks.

Demonstration is performed within the context of the ADRENALINE testbed® (All-optical Dynamic REliable Network hAndLINg IP/Ethernet Gigabit traffic with QoS), a GMPLS-enabled Intelligent Optical Network developed by the Optical Networking research area of the CTTC.

Architecture of the ADRENALINE Testbed®

ADRENALINE architecture has been conceived to jointly address the ever-growing and bursty bandwidth demands of IP data traffic, and the need of replacing the SONET/SDH nodes in transport core networks with cost-efficient solutions. The architecture leverages Connection-oriented Ethernet technologies (enabling flexible packet aggregation and grooming) along with the high-bandwidth offered by the reconfigurable wavelength-routed network functionality (providing end-to-end all-optical connections), both controlled by the intelligence provided by the GMPLS architecture and framework.

In the ADRENALINE testbed, we experimentally assess the application of a unified GMPLS control plane, in which Ethernet and optical layers are controlled by a single instance of the control plane, seamlessly providing reconfigurable Ethernet connections over dynamic lightpaths.

Advanced and adapted software applications and tools for experimental research have also been designed and deployed, allowing the rapid operation and maintenance of the testbed, including common tasks such as the configuration and parameterization of the network topology, the generation of client requests modelling the behaviour of network customers, or the monitoring, data-mining and statistical processing of obtained results allowing researchers to obtain numerical performance data and to perform experimental research and quantitative comparative analysis.

The ADRENALINE testbed® is composed of two main functional blocks; GMPLS-enabled Ethernet over WSON and GMPLS Control Plane Emulator with PCE.
