Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPNs) have seen an unparalleled increasing adoption in the last decade. Although their flexibility as transport technology and their effectiveness for traffic engineering are well recognized, VPNs are difficult to set up and manage, due to the complexity of configurations, to the number of(More)
Federated networking is a promising approach to resource sharing that supports cost-effective services involving multiple parties. Research in this field largely focused on architectures and cost models, making limited progress on the technological side. On the other hand, the widely adopted Software-Defined Networking (SDN) model found its most successful(More)
Federated networks have primarily emerged to support cloud computing services, in order to reduce costs for providers, as well as to increase their incomes. Up to now, the research activity has been mostly focused on architectures and cost models, setting aside technological aspects. In this paper, we propose SDNS, an SDN-system that opens the application(More)
Virtual Private Networks (VPNs) implemented by Multi Protocol Label Switching (MPLS) tunnels appear in the service offer of many Internet Service Providers (ISPs). Due to the number of technologies that they involve and to the intricacy of their interactions, provisioning, setup, and maintenance of VPNs is a cumbersome task, whose complexity is usually(More)
Internal routing inside an ISP network is the foundation for lots of services that generate revenue from the ISP's customers. A fine-grained control of paths taken by network traffic once it enters the ISP's network is therefore a crucial means to achieve a top-quality offer and, equally important, to enforce SLAs. Many widespread network technologies and(More)
In critical infrastructures, communication networks are used to exchange vital data among elements of Industrial Control Systems (ICSes). Due to the criticality of such systems and the increase of the cybersecurity risks in these contexts, best practices recommend the adoption of Intrusion Detection Systems (IDSes) as monitoring facilities. The choice of(More)
Software-Defined Networking (SDN) is a de-facto established approach that separates the packet switching functions of a device from its operational logic, which is controlled by a piece of software. Due to its potential for realizing new network architectures and services, a whole thread of scientific literature is devoted to SDN and its most adopted(More)
Mininet is the de-facto standard simulation environment for experimenting with SDN enabled networks based on the OpenFlow protocol. Although Mininet is powerful and not resource hungry, it has a strong limitation: it is not possible to use it for networks in which both OpenFlow and standard distributed routing protocols (e.g. Open Short Path First, OSPF)(More)
