Realizing the benefits of SDN for many network management applications (e.g., traffic engineering, service chaining, topology reconfiguration) involves addressing complex optimizations that are central to these problems. Unfortunately, such optimization problems require (a) significant manual effort and expertise to express and (b) non-trivial computation and/or carefully crafted heuristics to ...

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...

Software-defined network structure of the network fundamental changes, its network equipment to achieve the hardware and software isolation and virtualization technology underlying hardware, so as to further development of the network provides a platform. This is due to the hardware and software isolation, making the network more vulnerable to attack, thus changing the topology and business inf...

Software-defined networks (SDNs) pose both an opportunity and challenge to the network security community. The opportunity lies in the ability of SDN applications to express intelligent and agile threat mitigation logic against hostile flows, without the need for specialized inline hardware. However, the SDN community lacks a secure control-layer to manage the interactions between the applicati...

In the past few decades, the world has witnessed a rapid growth in mobile communication and reaped great benefits from it. Even though the fourth generation (4G) mobile communication system is just being deployed worldwide, proliferating mobile demands call for newer wireless communication technologies with even better performance. Consequently, the fifth generation (5G) system is already emerg...

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...

Computer networks have become a critical infrastructure. In fact, networks should not only meet strict requirements in terms of correctness, availability, and performance, but they should also be very flexible and support fast updates, e.g., due to policy changes, increasing traffic, or failures. This paper presents a structured survey of mechanisms and protocols to update computer networks in ...

Rapid increase in number and diversity of Internet-connected devices raises many challenges for the traditional network architecture, which is not designed to support a high level of scalability, real-time data delivery and mobility. To address these issues, in this paper we present a new model of Internet of Things architecture which combines benefits of two emerging technologies: software-def...

Today’s mobile customers desire to remain connected anywhere, at any-time and using any device. This phenomenon has encouraged the mobile network operators to build complex network architectures by incorporating new features and extensions, which are harder to manage and operate. In this paper, we propose a novel and simplified architecture for mobile networks. The proposed architecture, which ...
