“…OpenFlow, GMPLS/PCE) were coordinated by an SDN orchestrator in order to enable the automatic provisioning of E2E Ethernet transport services spanning a multi-layer and multi-domain network. Each domain provided its abstracted topology (node abstraction) to the multi-domain SDN orchestrator, which was based on the application-based network operations (ABNO) architecture [19,20]. The integrated cloud and network orchestrator was introduced here to provide joint orchestration of virtual machines (VM) and network resources.…”

Software-defined optical network has the combined benefit of both control flexibility and large transport capacity, thus having the potential of realizing a new ground-breaking optical network framework. In this paper, we introduce our recent efforts that have been devoted to the research supported by the STRAUSS project on SDN/Openflow controlled optical networks. The unified SDN control plane is able to configure the optical nodes/devices and thus the optical network through the cooperation of Openflow agents with more flexibility and optimization, thanks to its global knowledge of network resource and centralized controllability. Furthermore, we are able to interconnect our network with other heterogeneous multidomain networks, while demonstrating the end-to-end flexible service provisioning over both nationwide and international testbeds with SDN orchestration via unified interface based on control orchestration protocol.

Today's optical transport domains are typically built using fixed grid technology. They are statically configured and operationally intensive to manage, lacking the capability for dynamic services and elastic bandwidth. Recent research has established the benefits of flexible grid technologies for optical switching allowing dynamic and elastic management of the available bandwidth resources. Combined with Software Defined Networks (SDN) control principles and Network Functions Virtualization (NFV) infrastructure, we have the potential to fundamentally change the way we build, deploy and control network applications built on top of flexible optical networks.This paper outlines the current Internet Engineering Task Force (IETF) developments for standardizing flexible grid optical technologies, and discusses how software-defined and function virtualisation principles have and will continue to provide the key capabilities to further enable flexible optical switching technologies to control and deliver NFV-based services and applications. It addition it describes the benefits for the virtual Content Distribution Network (vCDN) use case when combined with an IETF's SDN framework Application-Based Network Operations (ABNO). Finally, we highlight the research opportunities for furthering the application of SDN and NFV for control and orchestration of flexible optical networks using the IETF ABNObased framework.

“…The NVC is responsible for: a) the interaction with a Network Orchestrator (NO) [5] for the deployment of the necessary multi-domain connectivity, b) the provision of a virtual network by enabling the abstracted network view to its customer (i.e., tenant) SDN controller, and c) the translation of the issued OF commands from the customer SDN controller to the necessary actions in the multi-domain network with interaction with the NO.…”

A network hypervisor is introduced to dynamically deploy multi-tenant virtual networks on top of multi-technology optical networks. It provides an abstract view of each virtual network and enables its control through an independent SDN controller. OCIS codes: (060.4250) Networks; (060.4258) Networks, network topology IntroductionTransport networks include different optical technologies (e.g., flexi-grid, OPS) and heterogeneous control technologies (e.g., OpenFlow -OF-, GMPLS/PCE), which enable flexible and dynamic networking but also create a multi-domain multi-technology network scenario in order to support end-to-end service provisioning. Such a transport network scenario raises challenges for efficient network control and operations. An SDN-enabled virtualization platform that allows abstracting and controlling a multi-domain multi-technology transport network is able to support rapid deployment of applications and network services and improve overall network operations. The creation and operation of multi-tenant virtual networks also allows better network utilization.Optical Network Virtualization has been respectively studied in a single GMPLS-controlled domain [1] and an OF domain [2]. In addition, the provision of a multi-domain Virtual Optical Network (VON) has also been proposed with the usage of per-domain virtualization [1]. A Network Orchestrator (NO) was introduced in order to provision end-to-end connectivity within a multi-domain VON.In order to achieve multi-domain virtualization, we propose the Network Virtualization Controller (NVC) as a network hypervisor to deploy multi-tenant VONs and allow their own customized control. The NVC runs over a NO, as shown in Fig. 1.a. NO is the responsible for providing end-to-end connectivity on top of multi-technology transport networks. The NVC is in-line with ACTN framework (IETF) [3] and SDN architecture (ONF) [4], where hierarchical SDN controllers have been considered to provide different layers of abstraction.
