Openflow: The future protocol

Abstract

With the emergence of networks defined by software Defined Networking (SDN), new projects that seek to optimize and control the traffic that runs through the communications networks have been opening. Openflow standard is proposed as one of these projects. This article aims to explain the Protocol in a simple language. It starts by referencing projects at global and national levels, to understand its usability and scope; it also seeks to know how the NGN (Next Generation Networks) transcend to a level where the user has less interaction with devices. New programming possibilities of alternative routes which can obtain the same results are proposed, without causing trauma to the previously designed traffic flows
