This paper presents a Software Defined Network (SDN) controller, called Cloud Networking Gateway (CNG) Manager, that enhances networking of distributed cloud resources and provides authorized customers with the ability to control and configure networks. The CNG Manager interconnects virtual machines acquired from distributed heterogeneous resources and services from multiple providers using a generic gateway. The cloud networking gateways are managed by the CNG Manager that handles allocation and configuration of the gateways according to connectivity requirements. Our implementation of the CNG Manager and the gateway is combined with an exact splitting algorithm and integrated in a cloud services provisioning system. The CNG Manager and the associated gateway extend the current state of the art by applying the SDN principle to connectivity control of distributed and networked cloud resources.

Network Service Chaining (NSC) is a service deployment concept that promises increased flexibility and cost efficiency for future carrier networks. NSC has received considerable attention in the standardization and research communities lately. However, NSC is largely undefined in the peer-reviewed literature. In fact, a literature review reveals that the role of NSC enabling technologies is up for discussion, and so are the key research challenges lying ahead. This paper addresses these topics by motivating our research interest towards advanced dynamic NSC and detailing the main aspects to be considered in the context of carrier-grade telecommunication networks. We present design considerations and system requirements alongside use cases that illustrate the advantages of adopting NSC. We detail prominent research challenges during the typical lifecycle of a network service chain in an operational telecommunications network, including service chain description, programming, deployment, and debugging, and summarize our security considerations. We conclude this paper with an outlook on future work in this area.

Network Service Providers should offer provisioning services with guaranteed Quality of Service (QoS), specifically adapted to the characteristics of the applications running on their network. In this paper we propose the Network Control Layer (NCL), a software framework solution based on Software Defined Networks (SDN), OpenFlow and Network as a Service (NaaS) paradigms. It addresses a major innovation area in the field of network control and management providing on-demand end-to-end network provisioning services with guaranteed QoS, based on the specific requirements of on-top running interactive applications. The NCL implementation is based on the OpenNaaS framework, and it includes mechanisms for network status monitoring and SDN switches configuration based on the interactive applications' QoS network requirements. We demonstrate NCL's utility in the context of control plane models making use of a practical use case.

The promises of Network Functions Virtualization (NFV) complemented with Software Defined Networking (SDN) can be simply stated as: get much more, pay much less. Adopting such paradigms, Service Operators expect to achieve high reductions in capital investments and greater operational agility. However, applying these concepts to existing networks will require challenging architectural updates, as well as deep changes in service models and operating procedures. To analyze such aspects, in this paper we provide an overview of the experience gathered at Italtel R&D labs in this field, and discuss state-of-the-art and future perspectives of these technologies. In particular, we describe how NFV was applied to a specific network function, the Session Border Controller, solving some related technical issues of general interest, and providing scalability and flexibility. Finally, we discuss the evolution of this virtualized network function, and its integration into an SDN-based network.

The pull of Software-Defined Networking (SDN) is magnetic. There are few in the networking community who have escaped its impact. As the benefits of network visibility and network device programmability are discussed, the question could be asked as to who exactly will benefit? Will it be the network operator or will it, in fact, be the network intruder? As SDN devices and systems hit the market, security in SDN must be raised on the agenda. This paper presents a comprehensive survey of the research relating to security in software-defined networking that has been carried out to date. Both the security enhancements to be derived from using the SDN framework and the security challenges introduced by the framework are discussed. By categorizing the existing work, a set of conclusions and proposals for future research directions are presented.

Network management is becoming increasingly challenging with the relentless growth in network size, traffic volume, and the diversity in QoS requirements. Traditionally, the concept of predefined Service Level Agreements (SLAs) has been utilized to establish QoS parameters. However, most state-of-the-art technologies in this area are both proprietary and inflexible. To this end, Software Defined Networking (SDN) has the potential to make network management tasks flexible, scalable, and an open platform to encourage innovation. In this paper, we present the design of PolicyCop, an open, flexible, and vendor agnostic QoS policy management framework targeted towards OpenFlow based SDN. PolicyCop provides an interface for specifying QoS SLAs and then exploits the control plane's API to enforce them. PolicyCop also monitors the network and autonomically readjusts network parameters to meet customer SLAs. We present experimental results to demonstrate PolicyCop's effectiveness in ensuring throughput, latency, and reliability guarantees.

Software Defined Networking (SDN) proposes the separation of the control plane from the data plane in network nodes. Furthermore, Openflow architecture through a centralized control of the packet forwarding engines enables the network administrators to literally program the network behavior. The research and results of experiments show clear advantages over traditional network architectures. However, there are open questions to be solved in order to integrate SDN infrastructure and applications in production networks. This paper presents an analysis of the evolution of SDN in recent years. Additionally, this piece of work also describes some interesting SDN/Openflow research initiatives and applications. Finally, there is a disscussion on the main challenges of this new technology.

Nowadays, Internet services demand for the mobilization of computing and storage resources located in proximity of the final users, and for the support of an agile and programmable network infrastructure. This calls for a holistic vision in which control, management, and optimization of both computing and networking resources are combined, resulting in a progressive blur of the capabilities of the latter towards the edges of the transport segment. However, due to its multi-provider nature, the Internet itself is the main obstacle to this change. In such a context, Network Virtualization (NV) and Software Defined Networking (SDN) solutions can enable business opportunities and provide technical benefits for the operators managing the different domains of a transport infrastructure. In this paper we discuss in detail the technical challenges and outline potential architectural approaches exploiting the above mentioned solutions to provide edge-to-edge virtualization, abstraction, control, and optimization of heterogeneous transport networks composed of both packet- and circuit- switched technologies.

In this paper, we show how to enable Information- Centric Networking (ICN) on existing IP networks, such as ISP or data center networks, using Software-Defined Networking (SDN) functions and control. We describe a mechanism that (i) enables addressing and transfer through non-SDN controlled networks (i. e., the Internet), (ii) allows to identify ICN requests and responses, (iii) decouples forwarding from the object name, (iv) requires neither new or extended network/L3 and transport/L4 protocols nor changes of client and server OS, and (v) supports aggregation of routes inside the SDN controlled network. In addition, the proposed solution is agnostic of the specific ICN protocol in use, and does not require all network elements to be SDN-enabled. It supports advanced ICN routing features like request aggregation and forking, as well as loadbalancing, traffic engineering, and explicit path steering (e. g., through ICN caches). We present the design as well as our first implementation of the proposed scheme-based on the Trema OpenFlow controller-framework and CCNx-along with initial performance measurements showing the feasibility of our approach.

The Software Defined Networks (SDNs) and Network Functions Virtualisation (NFVs), as recent separate research and development trends have the roots in programmable / active network technologies and standards developed a decade ago. In particular, they are associated with the decoupling of forwarding from control and hardware from networking software, using open interfaces to connectivity resources. The next phase of R&D would involve novel integration and use of all connectivity, storage and processing resources under new management interacting with control systems for provisioning of on-demand networking and services with continuous update of features. This brings into focus a relatively new and key topics for the next decade: what and how to create the conditions for effective and continuous updating and changing the networking functions without reinventing each time architectural aspects and related components (e.g. Softwarization of Future Networks and Services or Programmable Enabled Networks). This paper presents motivation, architecture and the key challenges in realising such programmable enabled networks as the next generation Software Defined Networks focusing on its management plane.
