Software-Defined Networking (SDN) as an emerging paradigm in networking divides the network architecture into three distinct layers such as application, control, and data layers. The multi-layered network architecture in SDN tremendously helps manage and control network traffic flows but each layer heavily relies on complex network policies. Managing and enforcing these network policies require...

Information Centric Networking (ICN) is a paradigm in which the network layer provides users with access to content by names, instead of providing communication channels between hosts. The ICN paradigm promises to offer a set of advantages with respect to existing (IP) networks for the support of the large majority of current traffic. In this paper, we consider the deployment of ICN by exploiti...

Distributed software-defined networks (SDN), consisting of multiple inter-connected network domains, each managed by one SDN controller, is an emerging networking architecture that offers balanced centralized control and distributed operations. Under such networking paradigm, most existing works focus on designing sophisticated controller-synchronization strategies to improve joint controller-d...

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 thatC. 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 tha...

Software defined networking (SDN) is an emerging approach to handle data forwarding and control separately. The notion of programmability has central importance in SDN. Two implementation strategies; proprietary and open source, are shaping the trends of the adoptability of SDN by major hardware manufacturers. A group of leading vendors believes that loose coupling between the logical and physi...

Software-defined networking (SDN), on account of its unprecedented capability of network traffic monitoring and data resource transferring, has been deployed into a wide range of application scenarios. However, typical cyber-attacks which prevail in traditional IP networks, have also mutated their implementation models adjusting to SDN environment. Eavesdropping is one of such attacks and cause...

Software Defined Networking (SDN) breaks the barrier of Internet innovation and has attracted tremendous attentions from both industrial and academic communities. Although OpenFlow is the de factor SDN protocol nowadays, which defines the interface between the data plane switches and the control plane controllers, there are emerging SDN proposals. Even for OpenFlow itself, it keeps evolving. As...

An interprocedural program dependence representation named the System Dependence Net (SDN) for occam 2 programs is presented. It is an extension of existing dependence representations to represent the full range of an occam 2 program in the sense that we construct the SDN to represent not only multiple procedures but also concurrency issues in the program. The SDN can be used as an underlaying ...

Software Defined Network (SDN) is a new architecture for network management and its main concept is centralizing network management in the network control level that has an overview of the network and determines the forwarding rules for switches and routers (the data level). Although this centralized control is the main advantage of SDN, it is also a single point of failure. If this main contro...

The Q neuroblasts in Caenorhabditis elegans display left-right asymmetry in their migration, with QR and descendants on the right migrating anteriorly, and QL and descendants on the left migrating posteriorly. Initial QR and QL migration is controlled by the transmembrane receptors UNC-40/DCC, PTP-3/LAR, and the Fat-like cadherin CDH-4. After initial migration, QL responds to an EGL-20/Wnt sign...
