Software Defined Networks (SDN) in data center networks

Abstract

Recently, new network services have emerged that have made the technologies we have been using for fifty years practically reach the limit of their capabilities. The appearance of Big Data, the introduction of cloud computing, applications in real time and the fact that modern communications are not exclusively between client and server, it is evident that a large amount of traffic is generated to the end user. To solve this increasing demand, temporary fixes have arisen, such as the creation of new protocols. However, these fixes do not solve the problem, and create the necessity of a global solution that faces the problems of modern networks and creates effective methods of communications. Hence, a new concept is born: Software Defined Networking (SDN), which implements a new architecture that delegates control of network devices from external software, called a controller, based on a protocol created for this purpose called OpenFlow. The general purpose of this project is the creation of a software environment that allow, by means of the integration of several elements, the implementation and testing of these networks. The results obtained show which network is best in terms of performance and features. As the network grows in elements, the performance of the Software Defined Networks is superior to that of the traditional network. These results prove that the SDN is the future networking architecture to implement in large datacenters as it introduces new features and improvements that the current business needs deman
