SDN and NFV convergence a technology enabler for abstracting and virtualising hardware and control of optical networks (invited)

Abstract: A new architecture utilizing combination of SDN and NFV for deeply programmable optical Internet infrastructure is proposed where network devices can be sliced, interconnected and programmed on demand for specific transport and network computing tasks.

Simple IP restoration for IP/GbE/10 GbE optical networks

Abstract: IP and Ethernet are the dominant transport and link-layer protocols in data networks. In this paper we demonstrate how IP can be used to provide reliable Ethernet transport with fast restoration performance comparable with that achieved in SONET networks.

An optical SDN Controller for Transport Network virtualization and autonomic operation

Abstract: This paper proposes an architecture for Software Defined Optical Transport Networks. The SDN Controller includes a network abstraction layer allowing the implementation of cognitive controls and policies for autonomic operation, based on global network view. Additionally, the controller implements a virtualized GMPLS control plane, offloading and simplifying the network elements, while unlocking the implementation of new services such as optical VPNs, optical network slicing, and keeping standard OIF interfaces, such as UNI and NNI. The concepts have been implemented and validated in a real testbed network formed by five DWDM nodes equipped with flexgrid WSS ROADMs.

Role of optical network infrastructure virtualization in data center connectivity and cloud computing

Abstract: A Datacenter as a Service architecture utilizing coordinated virtualization of distributed datacenters and operator's optical network is proposed. Two Optical network virtualization methods and a datacenter composition mechanism are introduced and their performance is evaluated.

On the benefits of lightpath re-provisioning in optical mesh networks

Abstract: A key means for improving service availability in optical networks is the ability to recover from dual near-simultaneous failures. To date, most studies have focused on improving survivability for single failure events either via proactive or reactive mechanisms. Conversely, lightpath re-provisioning has only recently been considered as an alternative for improving overall network restorability in the event of dual failures. Here, post-failure re-provisioning establishes new backup capacities for unprotected connections in advance of a second failure. In this paper we propose a new re-provisioning algorithm to improve the restorability of shared optical networks and compare its performance with a conventional scheme. Namely, the proposed algorithm only requires re-provisioning of a fraction of unprotected connections, since upon re-routing onto shared backup capacity, some connections are only in a "temporarily unprotected" state. Through simulation analysis, we demonstrate the effectiveness of the proposed approach in improving optical network restorability with and without wavelength conversion.
