While the novelty of Software-Defined Networking (SDN) — the separation of network control and data planes — is appealing and simple enough to foster massive vendor support, the resulting impact on the security of communication networks infrastructures and their management may be tremendous. The paradigm change affects the entire networking architecture. It involves new IP-based management comm...

Broadly construed, Software-Defined Networking (SDN) refers to the use of a standards-based open architecture and its supporting open source and open interfaces technologies to enable the deployment, management, and operation of networks. While traditional network management relies on vendor-specific hardware, protocols, and software, SDN systems are architected to have well-defined control and...

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...

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 Software-Defined Networking (SDN) paradigm is typically applied to data center and enterprise networks. We argue that SDN is also promising for rural wireless networks, especially those in developing regions. Operating a rural network in the developing world means coping with unpredictability, low profit margins, and resource constraints; the increased flexibility and simplified management ...

Software Defined Networking (SDN) and Network Function Virtualization (NFV) are two emerging and complementary concepts that can be considered as key players in the virtual networks world. In particular, SDN allows managing different network services through abstraction of higher-level functionality, while NFV leverages the use of virtualization technologies to virtualize specific network funct...

This paper proposes XML-Defined Network policies (XDNP) a new high level language based on XML notation to describe network control rules in Software Defined Network environments. We rely on existing OpenFlow controllers specifically Floodlight but the novelty of this project is to separate complicated languageand framework-specific APIs from policy descriptions. This separation makes it possib...

Managing today’s computer networks is a complex and error-prone task. These networks consist of a wide variety of devices, from routers and switches, to firewalls, network-address translators, load balancers, and intrusion-detection systems. Network administrators must express policies through tedious box-by-box configuration, while grappling with a multitude of protocols and baroque, vendor-sp...

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 ...
