The telecom industry has recently started to adapt the emerging paradigm of Software-Defined Networking (SDN) in combination with cloud computing to the telecommunication world. Both technologies enable a high degree of automation and flexibility for existing and novel networks. As this combination can reduce costs and enables the development of new business opportunities, telecom providers bui...

Software Defined Networks (SDN), the separation of a network device’s control and data planes, do not need to rely on the underlying network equipment (routers, switches, firewall).It is a new network which collaborated IP and a lot of relevant technical content. The control of SDN is completely open, the user can customize any rule strategy to achieve network routing and transmission, which is...

Future practical implementation of secure quantum communication technology in a multiuser network environment would require automatic monitoring of the optical link condition and quantum system parameters, along with adjusting them in real time according to protocol restrictions. We demonstrate how software-defined networking (SDN) paradigm can be used for addressing this problem on the example...

Software Defined Networking (SDN) is a network architecture that aims at providing high flexibility through the separation of the network logic from the forwarding functions. The industry has already widely adopted SDN and researchers thoroughly analyzed its vulnerabilities, proposing solutions to improve its security. However, we believe important security aspects of SDN are still left uninves...

Partha Datta has been working with Tata Consultancy Services (TCS) as Associate Head of Telecom Next Generation initiatives (telco cloud – Virtualization, Software Defined Networking, HetNet/SmallCells, Devices and Chipsets) with a focus on equipment vendors. With an experience of 15 years across leading telecom equipment vendors across the US and EMEA, Partha advocates a holistic view of the s...

Software Defined Network (SDN) has shown substantial benefits over the legacy network and fueled the implementation of a variety of innovative and intelligent applications on SDN Controller. However, these applications put the performance of SDN controller under question; since most of these applications excessively demand computing resources of SDN controller resulting in increased flow proces...

We consider an emerging class of challenging Internet applications called Real-Time Online Interactive Applications (ROIA). Examples of ROIA are multiplayer online games, computationand interaction-intensive training, simulationbased e-learning, etc. These applications make high QoS demands on the underlying network which involve the number of users and the actual application state and, therefo...

The introduction of Network Functions Virtualization (NFV) and Software Defined Networking (SDN) to mobile networks allows operators to control and dimension their network resources with higher granularity and on a more fine-grained time scale. This dynamic operation allows operators to save costs reacting to the rapid growth of traffic and user demands. In this paper, we model and analyze a re...

Network Coding (NC) shows great potential in various communication scenarios through changing the packet forwarding principles of current networks. It can improve not only throughput, latency, reliability and security but also alleviates the need of coordination in many cases. However, it is still controversial due to widespread misunderstandings on how to exploit the advantages of it. The aim ...

Software defined networking implements the network control plane in an external entity, rather than in each individual device as in conventional networks. This architectural difference implies a different design for control functions necessary for essential network properties, e.g., loop prevention and link redundancy. We explore how such differences redefine the security weaknesses in the SDN ...
