Cloud computing has generally involved the use of specialist data centres to support computation and data storage at a central site (or a limited number of sites). The motivation for this has come from the need to provide economies of scale (and subsequent reduction in cost) for supporting large scale computation for multiple user applications…

Selective Packet Inspection to Detect DoS Flooding Using Software Defined Networking (SDN)
Software-defined networking (SDN) and Open Flow have been driving new security applications and services. However, even if some of these studies provide interesting visions of what can be achieved, they stop short of presenting realistic application scenarios and experimental results. In this paper, we discuss a novel attack detection approach that coordinates monitors distributed over a network and controllers…
Round-robin based load balancing in Software Defined Networking
These days our networks have to handle large amount of traffic, serve thousands of clients. It is very difficult for a single server to handle such huge load. The solution is to use multiple servers with load balancer acting as a front end. The clients will send the requests to the load balancer. The load balancer will…
Mobility-aware QoS assurance in software-defined radio access networks: An analytical study
Software-defined networking (SDN) has gained a tremendous attention in the recent years, both in academia and industry. This revolutionary networking paradigm is an attempt to bring the advances in computer science and software engineering into the information and communications technology (ICT) domain. The aim of these efforts is to pave the way for completely programmable networks and control-data plane separation. Recent studies on…
Programmable hardware in software defined networking
Summary form only given. Software presents performance difficulties if it is the sole means of allowing programmability in high-speed optical SDN and NFV. Programmable hardware offers an ideal companion for implementing flexible SDN data planes and accelerating NFV functions.
Exploring the effects of monitoring and flow-rule timeout durations on load balancing in software defined networks
As more complex and distributed applications come into play in today’s Internet architecture, the need to have the adequate network architecture to support them with greater speed at lower costs has gained importance. Evolution in the nature of the applications have started to put significant stress on the networks and data centers which have to accommodate the demands of…
Real-time demonstration of software-defined Elastic interface for flexgrid networks
We demonstrate a real-time Elastic Interface for future flex-grid networks with a software-definedsymbol rate transmission. Using PDM-QPSK modulation, live experiments show a line rate adaptation from 10.7 to 107Gbit/s with a sub-millisecond reconfiguration time.
Route optimization for DASH over Software Defined Networks
In this paper, a method for the selection of the paths between the server and the clients for Dynamic Adaptive HTTP Streaming (DASH) over Software Defined Networks (SDN). In the proposed method, an optimization model is presented for increasing the Quality of Experience (QoE) in the clients by increasing the average received bitrates and for providing fairness by decreasing…
Software Defined Network controller embedded in mobile device for user’s policy implementation
Users run multiple applications simultaneously on single mobile device (MD) like mobile phone, tablet etc.. Utility and importance of different applications are not same and relative value depends on individual user. But in Internet architecture, available bandwidth is shared by applications equally. In wireless connection, fluctuation of bandwidth is common event and all applications are…
Cost Minimization for Rule Caching in Software Defined Networking
Software-Defined Networking (SDN) is an emerging network paradigm that simplifies networkmanagement by decoupling the control plane and data plane, such that switches become simple data forwarding devices and network management is controlled by logically centralized servers. In SDN-enabled networks, network flow is managed by a set of associated rules that are maintained by switches in their local Ternary Content Addressable Memories (TCAMs) which support high-speed…
