“…Previously, we have also reported on a multidomain, multitechnology (packet, fixed, and elastic) interoperation over an Openflow SDN-based unified control plane [39]. Web-services-based provisioning and control has also been used for deploying central management/control planes in several studies [40,41]. In this work and to facilitate the control of this open network platform, we have implemented a centrally controlled web-servicesbased control framework with a range of supporting software modules.…”

This paper reports on the design, implementation, and evaluation of a multitechnology, multirate, and adaptable network architecture for metropolitan/edge areas. It is empowered by programmability in control and data planes, providing users with an open network platform to redefine and optimize its behavior and performance. It uses a hybrid data plane of fixed-grid [(sub)wavelength] and flex-grid systems to support a broad range of data rates (1 to 555 Gb∕s). The programmability in the data plane is achieved by building the nodes with a modular and flexible architecture (architecture on demand nodes) to achieve different functionalities (fixed-/ flex-grid switching with or without time multiplexing) on demand. A centralized, modular, and scalable control framework has been constructed for this network. It uses a set of software plug-ins designed for architecture synthesis and adaptation for policing network resources access and as algorithms of routing and resource allocation for network operation. The proposed hybrid network architecture, along with allocation policies and resource allocation algorithms, is evaluated through simulations across a broad range of traffic profiles with bandwidth requests stretching from 1 to 400 Gb∕s. Finally, the programmable dataplane/control-plane architecture has been implemented in an experimental testbed and the functionality of the node and network elements individually and together have been tested, demonstrating the feasibility of the system.

“…As to the access of specific physical devices, [50] proposes a network management solution based on the SOA concepts. The desired final target is to reduce the gap between the services or applications that reside in the upper NGN layers and the real single devices, which inside a network contribute to delivery of the traffic data.…”

“…In the past, starting from this need, many research directions have led towards the concept of network programmability, and in this sense the presence of programmable interfaces and more in general of a middleware able to communicate with software applications and directly with physical devices has emerged. The solution proposed in [50] permits full control of every network device using a Web server proxy which is responsible for dispatching the control commands to the devices. Each WS exposes its own functionalities using an object oriented library, hiding the details of the communications with the physical devices.…”

The SOA (Service Oriented Architecture) paradigm has been driving the definition of important technologies in the telecommunication field for the last decade, as it fosters the deployment of reusable components to support efficient seamless services across different networks. Most of these technologies have focused on the definition of high-level network service interfaces and functionalities, such as Parlay-X and IMS, guaranteeing the success of the SOA model in the telco market after that of web applications. Some works proposing the adoption of this model in the lower network layers have also been proposed, but they have not proved to have the same impact yet.This paper intends to provide the reader with a survey of the works that have been proposed in this field by following the NGN (Next Generation Network) functional architecture as defined by the ITU-T. Specifically, we focus on the service and transport strata of the NGN model and, within each of these, we highlight the main logic functions that have been the subject of investigation according to a service-oriented approach. From the literature review, it can be seen that most of the works fall in service stratum, mostly because of the need for an easy integration of distributed service components at this layer. Only a few papers focus on the transport functionalities, where the benefits of applying the SOA paradigm still need to be investigated.
