Topology discovery is one of the most critical tasks of Software-Defined Network (SDN) controllers. Current SDN controllers use the OpenFlow Discovery Protocol (OFDP) as the de-facto protocol for discovering the underlying network topology. In a previous work, we have shown the functional, performance and security limitations of OFDP. In this paper, we introduce and detail a novel protocol call...

Worldwide, electrical grids are developing into smart grids. To ensure reliability, robustness and optimized resource usage, these grids will need to rely heavily on modern information and communication technologies. To support the achievement of these goals in communication networks, we evaluated the possibility of using software-defined networking (SDN) infrastructure based on OpenFlow, to pr...

Modern network management is foremost a case of precise control: to implement practical traffic engineering and network security policies, a network operator needs to control the exact path traffic takes through a network. While conceptually simple, accomplishing this level of control is surprisingly difficult with traditional network control planes; in the end, the underlying distributed routi...

This paper proposes a Software Defined Networking (SDN)-based active content networking architecture for future media environments. The proposed architecture aims to provide customized delivery of various types of media content in order to satisfy various demands of users and service requirements. To this end, we have developed an active content processing model which provides in-network conten...

The rapid rise in popularity of multimedia applications, such as VoIP, IPTV and Video Conferencing, intensifies the need to consider resource management for user satisfaction. Furthermore, improving Quality of Experience (QoE) in Software Defined Networks (SDNs) services is one of the important issues to be addressed by provisioning optimum resource management. In this paper, resource allocatio...

With the changing of network structure, software defined network becomes the main structure of the next generation network, which can realize network definition by the software programming according to the control platform, so that the network can be controlled. However, the network configuration is flexible and convenient, but also brings the problem of network security, so that the attacker c...

It is a great challenge to tackle the increasing threat of botnets to contemporary networks. The community developed a lot of approaches to detect botnets. Their fundamental idea differs and may be grouped according to the location (e.g., host-based, network-based), data sets (e.g., full network packets, packet header information), and algorithms (e.g., signature based, anomaly based). However,...
