Nowadays, Software Defined Network (SDN) architectures and applications are revolutionizing the way wired networks are built and operate. However, little is known about the potential of this disruptive technology in wireless mobile networks. In fact, SDN is based on a centralized network control principle, while existing mobile network protocols give emphasis on the distribution of network reso...

The new paradigm of Software-Defined Networking (SDN) enables exciting new functionality for building networks. Its core component is the so called SDN controller (also termed network operating system). An SDN controller is logically centralized and crucially important, thus, exploiting it can significantly harm SDN-based networks. As recent work considers only flaws and rudimentary malicious l...

Parts I, II and III of this four paper series detailed how software-defined networking (SDN) and network functions virtualization (NFV) are enabling a more flexible networking architecture compared to traditional approaches that use fixed-function network elements. They also described high-level hardware and software requirements for the SDN architecture, relevant Intel reference designs, and o...

The satellite industry is clearly committed to revisit and revamp the role of satellite communications within the 5G ecosystem. Central technologies being adopted in 5G networks such as Software Defined Networking (SDN) and Network Function Virtualization (NFV) are also anticipated to become key technological enablers for improved and more flexible hybridization of both satellite and terrestria...

Two complementary architectures, software defined networking (SDN) and network function virtualization (NFV) are emerging to comprehensively address several networking issues. In this work, we introduce the most embraced virtualization concepts proposed by SDN and NFV architectures. We quantitatively evaluate hardware and energy cost savings with these two SDN and NFV architectures compared to ...

Software-Defined Networking (SDN) offers programmers network-wide visibility and direct control over the underlying switches from a logically-centralized controller. SDN provides a promising way for the future development of Internet. SDN, however, also has some new security challenges. A critical challenge among them is how to build a reliable firewall application for SDN. Due to the stateless...

Software Defined Networking/Network Function Virtualization (SDN/NFV) is considered as a key technology for future mobile networks, such as 5G mobile communications systems. By 2020, the market size for Centralized-Radio Access Networks (C-RAN) will reach $21B. At the same time, enterprise Software Defined Data Center (SDDC) and the mobility market will increase to $77B and $360B, respectively....

Software-Defined Networking proposes to fundamentally change the current practice of network control. The two basic ideas are Centralized State Control and Uniform Device Abstraction, which support the Software-Defined promise. SDN has made significant progress. The opportunities of SDN in carrier access networks have been largely ignored by both industry and academia. In access networks, Quali...

With the evolution of the innovative software defined network (SDN), security issues have been taken into consideration. Intrusion prevention system (IPS) has widely deployed as a crucial measure in traditional network architecture to protect network from malignity. In spite of good capability of protection, IPS is still complained in many aspects, such as fixed deployment, single-point-detecti...
