Abstract Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance 1. Introduction†¦show more content†¦This is because, to implement any change to the network policies, the network engineers have to reconfigure each device individually to ensure a consistent set of access, security and QoS parameters. Further, with the evolution of Internet and enterprise data centers, the nature of data circulating on the Internet has also undergone a tremendous change. Data transfer in the form of video and audio is increasing at a tremendous pace[2]. Moreover, different sources of data (e.g.- mobile, tablet PCs) have placed considerable pressure on modern networks. The current capacities of network switches do not support the transfer of these mass amounts of data. Moreover, with advent of social media, amount of data generated on websites such as Facebook and LinkedIn has reached humungous levels. 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. 3. Software Defined Networking Software defined networking is a concept born out of the need to control network devices centrally, wherein the service offered by a device is decoupled from the device in a way thatShow MoreRelatedSoftware Defined Network For File Sharing867 Words   |  4 Pages Software Defined Networking Name: Nasrin, Mst. Sayma ID: 12-21985-2 Sec: B Introduction: We use Networks for file sharing, printer or peripheral sharing, Internet telephone service, multi-player games and many more. But, Normal networks are more complex. Configuring network devices requires a lot of effort and generally has to be done manually by devoted admin.

SOFTWARE DEFINED NETWORKS Cloud administrations are blasting and organizations are uniting their server farms all together to exploit the consistency, coherence and quality of the service. As the demand of network challenges and traffic increases network operator require new solutions. Software Defined Networking has emerged as the major player with potential solution. 3.1 WHAT IS SOFTWARE DEFINED NETWORK In the SDN architecture, the control and data planes are decoupled, network intelligenceRead MoreWhat Is The Middle Tier Of A Software-Defined Network?779 Words   |  4 PagesThe application tier of a software-defined networking architecture Software-defined networking (SDN) promises something akin to enterprise networking utopia by separating the control panel from the physical network topology to create an environment where all switches and routers take their traffic forwarding cues from a centralized management controller. In a software-defined networking environment, this software-based controller must have an end-to-end view of network resources and capacity. WithRead MoreProject : Enhancing Network Security Utilizing Software Defined Networks1257 Words   |  6 PagesState Of Art Project: Enhancing Network security Utilizing Software Defined Networks (SDN) The idea Internet technology was implemented in the early 1970’s. Rapid growth of the Internet is constantly being observed from the past two decades. Internet actually elevated the world of technology to the next level. It became so common that most day-to-day activities were dependent on the Internet. Mass usage of the Internet made things simple and was considered as one of the most reliable sources. ItRead MoreThe Influence Of Software Defined Networking On Network Industry Essay3570 Words   |  15 Pages ABSTRACT The influence of Software Defined Networking on network industry is immense. â€Å"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 the control plane and making networks programmable is a powerful one. If deployed in large scale, replacing the legacy networks architecture, it will empower serviceRead MoreNetwork Security Enhancement Using Software Defined Networking Technologies1810 Words   |  8 Pages â€Æ' Network Security enhancement using Software Defined Networking Technologies Software Defined Networking (SDN) is a pattern of new technologies for permitting more prominent control of how networks work. As opposed to a genuinely static network that must be controlled by exclusive merchant particular protocols, with at times restricted deceivability into the internals of layer 2 gadgets like switches, SDN considers experimentation in enhancing and arranging how the network functions. FurthermoreRead MoreDevelopment Of Multilayer Aggregate Switch Architecture For Data Center Network Using Software Defined Network2330 Words   |  10 PagesDEVELOPMENT OF MULTILAYER AGGREGATE SWITCH ARCHITECTURE FOR DATA CENTER NETWORK USING SOFTWARE DEFINED NETWORK MSEE Project Proposal By Abhash Malviya Ashmita Chakraborty Janhavi Tejomurtula Abhilash Naredla Signature Date Academic Advisor: Prof. Nadir F Mir ________________ __________________ Graduate Advisor: Prof. Thuy Le ________________ __________________ Department of Electrical EngineeringRead MoreUsing Edx Wireless Software Tool803 Words   |  4 Pagescareful selection of the firmware is required so that it matches with the requirements of our project. As far as software implementation is concerned, we have to learn the usage of SDR on GNU Radio or MATLAB platform for the successful working of our project. We have to figure out 802.11n protocol variant protocol for its implementation on an SDR in a way that provides viable network performance testing condition. The same has to be done for implementing LTE protocol on an SDR.
