Beneficios de las redes definidas por software y el protocolo openflow

Abstract

With the emergence of software-defined networks Defined Networking (SDN), and the use of the Openflow protocol in SDNs, new intelligent network architectures have evolved, bringing with them various advantages when applied together. On the other hand, the technological advances of the last decades, the development of new devices, higher transmission speeds, connectivity requirements, the development of new IoT applications and online services, make traditional network architectures that were thought to endure unsustainable over time and imposed as standards, today they are little used, such is the case of X.25, ATM, among others. therefore, a design evolution of these network architectures is demanden. At this point, the software defined network (SDN) together with the Openflow protocol appear as an evolution of a viable alternative network architecture that allows programming the network and opening the possibility of creating new services and more efficient applications to meet the requirements. Real in a centralized and programmable way. Finally, this work starts from a general context explaining the basic concepts related to software-defined networks, the types of controllers, layers and interfaces it handles. Subsequently, the advantages of SDNs over networks, virtualization will be determined and the use of the Openflow protocol in Programmable Networks will be identified. The article is made based con descriptive studies, information was obtained from various sources, such as articles from databases, web magazines, corporate pages and books.
