R ECENTLY, leading equipment providers in the network infrastructure market launched the first software-enabled appliances that support network virtualization capabilities. The main advantage of Software-Defined Networking (SDN) is the separation of network control and forwarding and the fact that it allows flexible management of the network resources. OpenFlow is currently the most prominent S...

Software defined networking (SDN) is a key enabling technology of industrial Internet of things (IIoT) that provides dynamic reconfiguration to improve data network robustness. In the context of smart grid infrastructure, the strong demand of seamless data transmission during critical events (e.g. failures or natural disturbances) seems to be fundamentally shifting energy attitude towards emerg...

Developing a systematic understanding of the attack surface of emergent networks, such as software-defined networks (SDNs), is necessary and arguably the starting point toward making it more secure. Prior studies have largely relied on ad hoc empirical methods to evaluate the security of various SDN elements from different perspectives. However, they have stopped short of converging on a system...

Wnt signals orient mitotic spindles in development, but it remains unclear how Wnt signaling is spatially controlled to achieve precise spindle orientation. Here, we show that C. elegans syndecan (SDN-1) is required for precise orientation of a mitotic spindle in response to a Wnt cue. We find that SDN-1 is the predominant heparan sulfate (HS) proteoglycan in the early C. elegans embryo, and th...

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, ...

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...

For a Software Defined Network (SDN), security is an important factor affecting its large-scale deployment. The existing security solutions for SDN mainly focus on the controller itself, which has to handle all the security protection tasks by using the programmability of the network. This will undoubtedly involve a heavy burden for the controller. More devastatingly, once the controller itself...

Cloud services are becoming centralized at several georeplicated datacentres. These services replicate data within a single datacentre to tolerate isolated failures. Unfortunately, disasters’ effects can not be entirely avoided, as existing approaches migrate a copy of data to backup datacentres only after data have been stored at a primary datacentre. Upon disaster, all data not yet migrated c...

Software defined networking (SDN) has been the buzzword among networking professionals since the last few years. The three tiered architecture of SDN promises to simplify the network management. Unfortunately, a significant amount of research that is going on in this field is focused on datacenter networks. The societal impact that this technology can bring about mostly in developing countries ...
