We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center (DC) applications. It adopts multicarrier modulation (MCM), either OFDM or DMT, and a cost-effective optoelectronic front-end. The high-capacity S-BVT is programmable, adaptive and reconfigurable by an SDN controller for efficient resource usage, enabling unique granularity, flexibility and grid adaptation, even in conventional fixed-grid networks. We experimentally demonstrate its multiple advanced functionalities in a four-node photonic mesh network. This includes SDN-enabled rate/distance adaptive multi-flow generation and routing/switching, slice-ability, flexibility and adaptability for the mitigation of spectrum fragmentation as well as for a soft migration towards the flexi-grid paradigm.

We propose the TelcoFog architecture as a novel, secure, highly distributed and ultradense fog computing infrastructure, which can be allocated at the extreme edge of a wired/wireless network for a Telecom Operator to provide multiple unified, cost-effective and new 5G services, such as Network Function Virtualization (NFV), Mobile Edge Computing (MEC), and services for third parties (e.g., smart cities, vertical industries or Internet of Things (IoT)).The distributed and programmable fog technologies that are proposed in TelcoFog are expected to strengthen the position of the Mobile Network and cloud markets. TelcoFog, by design, is capable of integrating an ecosystem for network operators willing to provide NFV, MEC and IoT services. TelcoFog key benefits are the dynamic deployment of new distributed low-latency services.The novel TelcoFog architecture consists of three main building blocks: a) a scalable TelcoFog node, that is seamlessly integrated in the Telecom infrastructure; b) a TelcoFog controller, focused on service assurance and based on service data modeling using YANG, that is integrated in the management and orchestration architecture of the Telecom operator; and c) TelcoFog services, which are able to run on top of the TelcoFog and Telecom infrastructure. The TelcoFog architecture is validated through a Proof of Concept for IoT services.

The fifth generation of mobile networks (5G) and the internet of Things (IoT) impose very stringent requirements to the optical transport networks. On the one hand, high flexibility, ultra-low latency and high capacity, in order to support the forecasted 1000x growth in mobile data traffic with latencies below millisecond. On the other hand, massive edge and core cloud infrastructure integrated with the transport network to dynamically deploy NFV, MEC, and IoT analytics. This paper presents ADRENALINTE testbed, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.

We experimentally demonstrate multiple advanced functionalities of a cost-effective high-capacity sliceable-BVT using multicarrier technology. It is programmable, adaptive and reconfigurable by an SDN controller for efficient resource usage, enabling unique granularity, flexibility and grid adaptation, even in conventional fixed-grid networks

We propose the combination of optical network virtualization and NFV for deployment of on-demand OpenFlowcontrolled Virtual Optical Networks (VON). Each tenant SDN controller is run on the cloud, so the tenant can control the deployed VON. This paper demonstrates the feasibility of the proposed use case and provides implementation details in the ADRENALINE testbed of a NFV orchestrator, which is able to provide multitenancy on top of an heterogeneous transport network by means of network orchestration and virtualization.

The Control Orchestration Protocol (COP) abstracts a common set of control plane functions used by an various SDN controllers, allowing the interworking of heterogeneous control plane paradigms (i.e., OpenFlow, GMPLS/PCE). COP has been defined using YANG model language and can be transported using RESTconf, which is being incorporated by industry. COP has been defined in the scope of STRAUSS due to the need for an overarching control plane protocol for network orchestration. In this paper, several research projects describe how the COP could fit in their architecture and propose a use case for COP usage. The proposed COP use cases cover the following research projects: STRAUSS, IDEALIST, DISCUS, COMBO, INSPACE.
