Software-Defined Networking-based Mobile Networks (SDN-MNs) are considered the future of 5G mobile network architecture. With the evolving cyber-attack threat, security assessments need to be performed in the network management. Due to the distinctive features of SDN-MNs, such as their dynamic nature and complexity, traditional network security assessment methodologies cannot be applied directl...

-With the rapid development of Internet, the complexity of the network and control difficulty has increased dramatically. For the problem of fossilization network is more and more prominent, SDN (software defined network) arises at the historic moment. Due to SDN controller centralized control and the characteristics of shunt on SDN network equipment, this paper puts forward that part of nodes ...

The architectural principles of Software-Defined Networking (SDN) and its most prominent supporting protocol OpenFlow keep gaining momentum. SDN relies essentially on the decoupling of the control plane from the data plane, placing the former in a logically centralized component to be executed on commodity hardware the SDN controller. OpenFlow’s reactive programming enables the programming of t...

Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN, a fr...

the goal of this work is to present a case study demonstrator, presenting the field trial experience while extending network connectivity services in the campus, by enabling SDN-based equipment and coexisting with legacy hardware. The demonstrator aims to show the benefits of gradually adopting SDN technologies. This adoption will also improve and provide added value to traditional campus conne...

In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on “SDN for Future Networks and Services” (SDN4FNS’13) was organized in Trento, Italy (Nov. 11-13 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-...

Middleboxes provide key security and performance guarantees in networks. Unfortunately, the dynamic traffic modifications they induce make it difficult to reason about network management tasks such as access control, accounting, and diagnostics. This also makes it difficult to integrate middleboxes into SDN-capable networks and leverage the benefits that SDN can offer. In response, we develop t...

Software-Defined Networking promises to overcome vendor lock-in by enabling a multi-vendor hardware and software ecosystem in operator networks. However, we observe that this is currently not happening. A framework allowing to compose SDN applications combining different frameworks can help revert the trend. In this paper, we analyze the challenges in the current SDN landscape and then present ...

Software-Defined Networking (SDN) has significantly enriched network functionalities by decoupling programmable network controllers from the network hardware. Because SDN controllers are serving as the brain of the entire network, their security and reliability are of extreme importance. For the first time in the literature, we introduce a novel attack against SDN networks that can cause seriou...

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...
