Demonstrating resilient quality of service in software defined networking Ghent University
Software defined Networking (SDN) such as Open-Flow decouples the control plane from forwarding devices and embeds it into one or more external entities called controllers. We implemented a framework in OpenFlow through which business customers receive higher Quality of Service (QoS) than best-effort customers in all conditions (e. g. failure conditions). In the demonstration, we stream video clips (business and best-effort customer's traffic) ...
Implementing quality of service for the software defined networking enabled future internet Ghent University
Software defined networking: meeting carrier grade requirements Ghent University
Software Defined Networking is a networking paradigm which allows network operators to manage networking elements using software running on an external server. This is accomplished by a split in the architecture between the forwarding element and the control element. Two technologies which allow this split for packet networks are ForCES and Openflow. We present energy efficiency and resilience aspects of carrier grade networks which can be met ...
Vehicular Data Offloading by Road-Side Units Using Intelligent Software Defined Network Hasselt University
The evolution of wide variety of applications that are used by vehicular users includes a lot of data hungry applications. This increases the workload on the cellular networks, thereby delivering poor service to the users. We can overcome this problem by sharing this workload with open wireless networks. As such, this improves the Quality of Service provided by cellular networks. RoadSide Units (RSU) are a wireless network which plays a major ...
Enabling virtual radio functions on software defined radio for future wireless networks University of Antwerp KU Leuven Ghent University
Today's wired networks have become highly flexible, thanks to the fact that an increasing number of functionalities are realized by software rather than dedicated hardware. This trend is still in its early stages for wireless networks, but it has the potential to improve the network's flexibility and resource utilization regarding both the abundant computational resources and the scarce radio spectrum resources. In this work we provide an ...
Secure communication channel architecture for Software Defined Mobile Networks Vrije Universiteit Brussel
A Software-Defined Mobile Network (SDMN) architecture is proposed to enhance the performance, flexibility, and scalability of today’s telecommunication networks. However, SDMN features such as centralized controlling, network programmability, and virtualization introduce new security challenges to telecommunication networks. In this article, we present security challenges related to SDMN communication channels (i.e., control and data channel) ...
Proactive mobility management of software defined wireless networks University of Antwerp
Wireless networks are a very complex and dynamic environment that requires proper management to optimise its performance. With a tremendous increase in the number of user devices and their data traffic, wireless networks are becoming denser. Therefore, optimising mobility management becomes a crucial challenge. In heterogeneous wireless networks, the usage of multiple wireless interfaces is inefficient and suboptimal. Solutions require ...
