Lab Trial of PCE-based OSNR-aware Dynamic Restoration in Multi-domain GMPLS-enabled Translucent WSON
Lei Liu1, Ramon Casellas1, Takehiro Tsuritani1, Itsuro Morita1, Ricardo Martínez2, Raül Muñoz2; 1KDDI R&D Laboratories Inc., Japan; 2Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), Spain.
We experimentally present a lab trial of PCE-based OSNR-aware dynamic restoration in multi-domain GMPLS-enabled translucent WSON, assessing the overall feasibility and quantitatively evaluating the service disruption time and path computation latency during end-to-end lightpath restoration.

OpenFlow-based Wavelength Path Control in Transparent Optical Networks: a Proof-of-Concept Demonstration
Lei Liu1, Takehiro Tsuritani1, Itsuro Morita1, Hongxiang Guo2, Jian Wu2; 1KDDI R&D Laboratories Inc., Japan; 2Beijing University of Posts and Telecommunications (BUPT), China.
We experimentally present a proof-of-concept demonstration of OpenFlow-based wavelength path control for lightpath provisioning in transparent optical networks, assessing its overall feasibility and quantitatively evaluating the network performances.

PCE Architecture for Flexible WSON enabling Dynamic Rerouting with Modulation Format Adaptation
Gianluca Meloni1, Francesco Paolucci1, Nicola Sambo1, Filippo Cugini2, Marco Secondini1, Luca Gerardi1, Luca Potì2, Piero Castoldi1; 1TECIP, Scuola Superiore Sant'Anna, Italy; 2CNIT, Italy.
An advanced PCE architecture, exploiting novel PCEP extensions for flexible-grid optical networks, is proposed and experimentally validated with dynamic frequency slot assignment and format adaptation from DP-16QAM to DP-QPSK at 100Gb/s.

Dynamic Distributed Spectrum Allocation in GMPLS-controlled Elastic Optical Networks
Raul Munoz1, Ramon Casellas1, Ricardo Martinez1; 1Optical Networking, CTTC, Spain.
We propose and experimentally evaluate a distributed spectrum assignment approach for GMPLS-controlled elastic networks based on collecting the frequency slot availability information during the signaling phase and performing efficient spectrum allocation at the destination node.

Integrated OpenFlow - GMPLS Control Plane: An Overlay Model for Software Defined Packet over Optical Networks
Siamak Azodolmolky1, Reza Nejabati1, Eduard Escalona1, Ramanujam Jayakumar1, Nikolaos Efstathiou1, Dimitra Simeonidou1; 1CSEE, High Performance Networks group, University of Essex, United Kingdom.
A novel software-defined packet over optical networks solution based on the OpenFlow and GMPLS control plane integration is demonstrated. The proposed architecture, experimental setup, and average flow setup time for different optical flows is reported
