Column generation algorithms for virtual network embedding in flexi-grid optical networks
Optics Express, 2018 Network virtualization provides means for efficient management of network resources by embedding multiple virtual networks (VNs) to share efficiently the same substrate network. Such virtual network embedding (VNE) gives rise to a challenging problem of how to optimize resource allocation to VNs and to guarantee their performance requirements.

Dynamic and Adaptive Control Plane Solutions for Flexi-Grid Optical Networks Based on Stateful PCE [PDF]
Journal of Lightwave Technology, 2014 Adaptive flexi-grid optical networks should be able to autonomously decide where and when to dynamically setup, reoptimize, and release elastic optical connections, in reaction to network state changes. A stateful path computation element (PCE) is a key element for the introduction of dynamics and adaptation in generalized multiprotocol label switching

Multi-domain overarching control of flexi-grid networks with GMPLS as Inter-SDN controller communication [PDF]
Optical Fiber Communication Conference, 2015 We report the experimental assessment of a hybrid control plane for multi-domain, heterogeneous networks based on abstraction and hierarchical TE. A mesh of SDN controllers use GMPLS protocols as East/West interfaces, forming an abstracted topology.

SDN based Provisioning Orchestration of OpenFlow/GMPLS Flexi-grid Networks with a Stateful Hierarchical PCE [PDF]
Optical Fiber Communication Conference, 2014 We report the experimental testbed evaluation of connectivity provisioning in which OpenFlow and GMPLS control planes interwork by means of an orchestrating stateful PCE. The hierarchical nature of the PCE allows seamless multi-domain operation.

The voice of the Toowoomba Flexi School student
, 2014 This chapter captures the voice of students who attend the Toowoomba Flexi School, a school for disengaged and disenfranchised youth. Similar to the approach taken by cultural anthropologists, the authors draw on their observations as well as face-to ...

Distributed vs. Centralized PCE-based Transport SDN Controller for Flexi-Grid Optical Networks [PDF]
Optical Fiber Communication Conference, 2017 We validate the use of a centralized PCE architecture as an SDN controller to compute and configure flexi-grid optical networks. Besides presenting new PCEP extensions, performance evaluation compares PCE-based solution with traditional distributed signaling approach.
