Software-Defined Networking: An Evolving Network Architecture—Programmability and Security Perspective

Software-defined networking: the service provider perspective

Software defined networking and network function virtualization

The Federal Aviation Administration (FAA) Telecommunications Infrastructure (FTI) network is an essential component for the day-to-day FAA mission. In this digital era where quick access to information is essential, the FTI network has grown significantly and is used to transport data, services, and information for the National Airspace System (NAS). Whether the follow-on network FTI-2 is compl...

Improving Network Management with Software Defined Networking

Network Management is very challenging. The Maintenance, operating and providing a secured communication network is very complex. It requires the network operators to grapple low-level vendor specific configurations to implement the high level network policies which are complex. The rigidity of underlying infrastructure presents few possibilities of improvement or innovation, since network devi...

Robust Composition of Network and Security Applications using Software-Defined Networking

As SDN deployments mature, operators need to manage and compose multiple applications. Of particular interest are security and networking applications that measure as traffic engineering and service chaining, among others. In the absence of suitable composition abstractions, prior approaches result in suboptimal resource utilization, unfairness, and/or require applications to be rewritten to be...

Enabling Practical Software-defined Networking Security Applications with OFX

Software Defined Networks (SDNs) are an appealing platform for network security applications. However, existing approaches to building security applications on SDNs are not practical because of performance and deployment challenges. Network security applications often need to analyze and process traffic in more advanced ways than SDN data plane implementations, such as OpenFlow, allow. Much of ...
