I. ABSTRACT “SDN industry is expected to surpass 35 billion in next five years” concluded by SDNcentral after conducting a market research on the impact of SDN on network industry. Clearly the impact is huge. Why? Because the concept of decoupling data plane from control plane and making networks programmable is a powerful one. If deployed in large scale, replacing the legacy networks architecture, it will empower service providers and operators to deploy new services, provide freedom from proprietary vendor specific network solutions while providing greater control over the network. However, this future vision of networks and SDN cannot be realized if one of the criteria of large scale acceptance is overlooked, i.e. how secure is networking the SDN way. In this paper I analyze the various vulnerabilities which can be exploited if SDN architecture is deployed on large scale. II. INTRODUCTION In traditional networking architecture, control plane and data plane are coupled in the network infrastructure. This traditional architecture has many inherent issues: 1. Traditional Networks are very hard to manage. With ever increasing size of networks, it becomes very difficult to manage and interoperate heterogeneous devices. Control plane is distributed in each infrastructure devices. 2. Cost of managing traditional networks are very high. One, the network infrastructure devices like routers, switches are very costly. Two, very highly skilled workforce is required with knowledge of

amid this configuration we tend to look for guidance from them as data, control, and application planes. At base, the data plane is included system segments, whose SDN Data ways uncover their abilities through the Control-Data-Plane Interface (CDPI) Agent. On top, SDN Applications exist inside of the application plane, and impart their needs by means of northward Interface (NBI) Drivers. inside of the centre, the SDN Controller interprets these needs and applies low-level administration over the SDN Data ways, while giving pertinent data up to the SDN

The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.
Network improvement has become follower in today’s modern life. The more we work the more we are affected to network and thus normally having always new requirements. To implement more efficient methods is needed first to predicate them. This predication needs to be developed before the requirements are very high. Users always expect more from networking while they compare old and current methods they’re working on. If network improvement performs poorly it would damage many businesses, consumer satisfaction etc, thus forthcoming of network should always be improved and not go down. One of the greatest improvements made on network field was
Networking is not new; it has been around for a long time. The way networking is done changes all the time; let’s look briefly at the past and how networking has changed over the years.
Brocade is fully invested in making SDN completely modular to deliver New IP networks based on an open ecosystem. The Brocade SDN Controller is continuously built from the OpenDaylight code, with a virtuous cycle of contributions back to the OpenDaylight community. Physical and virtual networks from multiple vendors can be managed within the Brocade SDN Controller, and organizations can gradually introduce ever-larger portions of their existing networks into the controller domain with single-source technical support for the entire

The setup and implementation of a computer network seems to be a daunting task as there are many factors
Internet based Wide Area Network virtualization technologies, virtualized network functions, overlays, automation technologies, and virtual network appliance solutions must be implemented where applicable for all network layers to improve infrastructure agility, efficiency, and reduced power consumption and physical foot print.
As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.
