These days the usage of network is growing at a faster pace, at the same time a lot of challenges is facing by the network administrator, to tackle the frequent network access by the users. The network infrastructure is growing rapidly to meet the business need, but it requires re-policing and reconfiguration of the network. But managing the underlying infrastructure becomes more complicated to handle the unprecedented network demand. The Software Defined Network (SDN), is the next generation Internet technology, which not only solves the ossification of the Internet, but also creates innovations and simplifies the network management. The key idea behind SDN is separation of control plane from the data plane, as a result, devices in the data plane simple becomes the forwarding device and transfer all the decisionmaking activities in a centralized system called a controller. Among many, OpenFlow is the standard and most popular SDN protocol that interacts between controller and forwarding devices. In this article, we will give an overview of the basic architecture of SDN and OpenFlow, SDN-controller interaction and benefits of SDN.

A Survey and a Comparative Study on Software-Defined Networking
— Software-Defined Networking (SDN) is a new networking paradigm in network technologies in which the data plane and network plane are separated. This new technology began to be widely used in last few years and studies started to increase on this new technology. The communication scheme of the network consists mainly of the controller and programmable OpenFlow switches. The centralized controller can be considered as the brain of the network which is basically responsible on determining the path of the incoming packet by informing the switches to route that packet in the right direction. In this paper, a complete definition and description have been shown and a survey study on the SDN has been presented based on different types of studies have been already made historically. An overview on the simulators used to implement these networks has also been shown.
A Study of Software Defined Networking
The Internet, a collection of networks allows transmission of information from one place to another. Today's internet is growing fast, devices to the network for accessing and providing the services. The Traditional network makes it a difficult task to add and remove the network devices. The Static Nature of the conventional network makes it difficult to accomplish the dynamic computing and storage desires of big data centers and campuses. Software-Defined Networking is the new approach to networking. Software Defined Network model promises to simplify the network configuration and resource management. Software Defined Networking will replace the current network and fulfill the business needs via software rather than hardware. This paper introduces the concepts of Software Defined Network which will help to configure and manage the network needs.
Introduction to Software Defined Networks (SDN
Legacy IP networks are complex, difficult to manage and are also vertically integrated i.e. the control and data planes are bundled together. The concept behind Software Defined Networks (SDN) is to break the vertical integration, by separating the network control logic from its underlying hardware, (routers and switches) promoting (logical) centralization of network control, and introducing the ability to program the network. In this paper, we start by introducing the motivation for SDN, its architecture and how it differs from traditional networking. Open flow is discussed next and SDN simulation tools are also discussed. The applications and main ongoing research efforts and challenges of SDN are also mentioned.
This paper will give an idea about Software defined networking(SDN) & to make familiar with this upcomming technology. Since its an emerging technology under computer networking.Here is an overview as to how SDN is better than traditional IP networks.Implementation of SDN would be great since the programming ability can be done on a single controller and the network administrator can have a abstract view over the network.

Software Defined Networking and its Challenges
2021
Trends (e.g., versatile, social, cloud, and huge information) in information and communication technologies (ICT) are instructing new difficulties to future Internet, that pervasive openness, high transfer speed, and dynamic administration are crucial. However, old methodologies upheld manual configuration of exclusive gadgets are awkward and blunder inclined, and that they can't completely use the capability of actual network infrastructure. As of late, Software Defined Networking (SDN) has been promoted together of the most promising answers for future Internet. SDN is described by its two recognized highlights, including decoupling the control plane from the information plane and giving programmability to arrange application advancement. Therefore, SDN is expected to supply more proficient setup, better execution, and better adaptability to oblige imaginative organization plans. Software defined networking offers a few advantages for networking by isolating the control plane ...
Comparison of Software Defined Networking with Traditional Networking
Asian Journal of Research in Computer Science, 2021
The Internet has caused the advent of a digital society; wherein almost everything is connected and available from any place. Thus, regardless of their extensive adoption, traditional IP networks are yet complicated and arduous to operate. Therefore, there is difficulty in configuring the network in line with the predefined procedures and responding to the load modifications and faults through network reconfiguring. The current networks are likewise vertically incorporated to make matters far more complicated: the control and data planes are bundled collectively. Software-Defined Networking (SDN) is an emerging concept which aims to change this situation by breaking vertical incorporation, promoting the logical centralization of the network control, separating the network control logic from the basic switches and routers, and enabling the network programming. The segregation of concerns identified between the policies concept of network, their implementation in hardware switching and data forwarding is essential to the flexibility required: SDN makes it less Review Article complicated and facilitates to make and introduce new concepts in networking through breaking the issue of the network control into tractable parts, simplifies the network management and facilitate the development of the network. In this paper, the SDN is reviewed; it introduces SDN, explaining its core concepts, how it varies from traditional Furthermore, we presented the crucial advantages and challenges of SDN security, flexibility, and performance. Finally, a brief conclusion of SDN is revised.
