In this paper, Enhanced Interior Gateway Routing Protocol (EIGRP) algorithm inside routers will be applied along with simple smart load distribution algorithm inside a controller which results a network that has the characteristics of the OpenFlow protocol. OpenFlow protocol is a powerful method to deal with changing of traffic volumes across the links and it involves using a Controller that ma...

Software-Defined Networking (SDN) offers programmers network-wide visibility and direct control over the underlying switches from a logically-centralized controller. SDN provides a promising way for the future development of Internet. SDN, however, also has some new security challenges. A critical challenge among them is how to build a reliable firewall application for SDN. Due to the stateless...

OpenFlow allows network administrators to manage the behavior of their network by running a software application on a network controller device. This network element can insert dynamic control flow policies by modifying the flow tables of each switch and create interconnecting paths between the other elements of the network. Due to the fact that Software Defined Networking is a new concept prom...

We are witnessing a rapid growth in communication, and current networks are becoming larger and more complex. Many works point to the use of Software-Defined Networking (SDN) and the OpenFlow protocol as enabling technologies to overcome current limitations. As the use of software-based simulation is a straightforward option for researchers in this area, the main contribution of this work is th...

Multimedia streaming applications have stringent Quality of Service (QoS) requirements which cannot be always met by the best-effort Internet. To provide QoS, several QoS architectures have been explored over last two decades, but none of them has been truly successful and globally implemented. This thesis presents a novel QoS architecture for multimedia streaming based on OpenFlow, a Software ...

Abstract—Recently, attention is particularly focused on the research of Software defined network (SDN) for reducing network management complexity. The one of a key technology of SDN is OpenFlow. OpenFlow provide a centralized controller for network and the scalability of controller is main issue. In this paper, we propose a high-speed routing engine for improve the scalability of OpenFlow contr...

There have been many attempts to unify the control and management of circuit and packet switched networks, but none have taken hold. In this paper we propose a simple way to unify both types of network using OpenFlow. The basic idea is that a simple flow abstraction fits well with both types of network, provides a common paradigm for control, and makes it easy to insert new functionality into t...

OpenFlow, originally proposed for campus and enterprise network experimentation, has become a promising SDN architecture that is considered as a widely-deployable production network node recently. It is, in a consequence, pointed out that OpenFlow cannot scale and replace today’s versatile network devices due to its limited scalability and flexibility. In this paper, we propose OpenQFlow, a nov...
