Research work provides efficient security which protects network resources from internal and external threats. Network virtualization is used to provide users with well-organized, controlled, and safe sharing of the networking resources. It also ensures privacy of data and integrity in Software-defined data center (SDDC) whose infrastructures is virtualized and distributed as a service. SDDC he...

In the last few years, the emerging network architecture paradigm of Software-Defined Networking (SDN), has become one of the most important technology to manage large scale networks such as Vehicular Ad-hoc Networks (VANETs). Recently, several works have shown interest in the use of SDN paradigm in VANETs. SDN brings flexibility, scalability and management facility to current VANETs. However, ...

Adoption of Software Defined Networking (SDN) remains largely confined to data center networks, where network architects frequently have the luxury of designing and deploying within a tightly controlled greenfield environment. In comparison, adoption of SDN technologies within existing ISP and enterprise networks depends on the network operator’s ability to evaluate SDN’s impact and define a tr...

Software Defined Networking (SDN) introduces programability into the network forwarding plane and simultaneously enables architectural refactoring of the routing control plane. In this work, we present two complementary studies leveraging the opportunities presented by SDN. First, in the context of internet router architectures in Section II, we propose leveraging OpenFlow forwarding informatio...

Software bugs are inevitable in software-defined networking (SDN) control planes, and troubleshooting is a tedious, time-consuming task. In this paper we discuss how one might improve SDN network troubleshooting by presenting a technique, retrospective causal inference, for automatically identifying a minimal sequence of inputs responsible for triggering a given bug in the control software. Ret...

Plug-and-play information technology (IT) infrastructure has been expanding very rapidly in recent years. With the advent of cloud computing, many ecosystem and business paradigms are encountering potential changes and may be able to eliminate their IT infrastructure maintenance processes. Real-time performance and high availability requirements have induced telecom networks to adopt the new co...

The Software Defined Networking (SDN) paradigm introduces separation of data and control planes for flow-switched networks and enables different approaches to network security than those existing in present IP networks. The centralized control plane, i.e. the SDN controller, can host new security services that profit from the global view of the network and from direct control of switches. Some ...
