The operational challenges posed in enterprise networks, present an appealing opportunity for the software-defined orchestration of the network (SDN). However, the primary challenge to realizing solutions built on SDN in the enterprise is the deployment problem. Unlike in the data-center, network upgrades in the enterprise start with the existing deployment and are budget and resource-constrain...

The operational challenges posed in enterprise networks present an appealing opportunity for automated orchestration by way of Software-Defined Networking (SDN). The primary challenge to SDN adoption in the enterprise is the deployment problem: How to deploy and operate a network consisting of both legacy and SDN switches, while benefiting from simplified management and enhanced flexibility of ...

Network function virtualization (NFV) and Software Defined Networking (SDN) are widely acknowledged as potential disruptive technologies of next generation computer networks. The network operators are pushing the frontiers of NFV to reduce operational expenditure (OPEX) and capital expenditure (CAPEX). Network vendors and academic researchers look upon NFV as an opportunity to speed up innovati...

SDN and NFV are modern techniques to implement networking infrastructures and can be used also to implement other advanced functionalities, such as the protection architecture designed by the SECURED project. This paper discusses a couple of techniques – trustworthy network infrastructure monitoring and remote attestation of virtual machines – useful towards a trusted and secure usage of SDN an...

We propose the object-oriented networking (OON) framework, for meeting the generalized interconnection, mobility and technology integration requirements underlining the Internet. In OON, the various objects that need to be accessed through the Internet (content, smart things, services, people, etc.) are viewed as network layer resources, rather than as application layer resources as in the IP c...

In this paper, the potential security issues brought by the virtualization of a Software Defined Networks (SDN) would be analyzed. The virtualization of SDN is achieved by FlowVisor (FV). With FV, a physical network is divided into multiple isolated logical networks while the underlying resources are still shared by different slices (isolated logical networks). However, along with the benefits ...

The pull of Software-Defined Network- ing (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 mark...

Two complementary architectures, software defined networking (SDN) and network function virtualization (NFV) are emerging to comprehensively address several networking issues. In this work, we introduce the most embraced virtualization concepts proposed by SDN and NFV architectures. We quantitatively evaluate hardware and energy cost savings with these two SDN and NFV architectures compared to ...

Software Defined Networking (SDN) defines a network architecture in which the control plane is managed by a logically centralized controller, and thus configuration updates occur frequently. We have recently introduced an approach that uses time-based configuration updates, allowing to simplify complex update procedures and to minimize transient effects caused by configuration changes. This pap...
