Software-defined network: o fim do monopólio comercial e incompatibilidades entre os fabricantes

Abstract

Software Defined Network's main objective (besides improving network performance) is to standardize the way data packets are treated in network devices, regardless of Manufacturers, the protocols that control the flow, as well as the Open Flow and their respective devices that intelligently split into specific functions, promoting better dedication in its tasks, are the biggest responsible for all this evolution, treating and preventing network bottlenecks that are caused by queue delays (buffer), processing, transmission time and RTT (Round-trip Delay Time). Despite the way Software Defined Networks with Open Flow treat the flow of data and a relevant form of control compared to the conventional TCP/IP, there are researchers who do not consider it a revolution, but an evolution of other techniques that have centralization as the main objective, just like VoIP where there is the proxy server and the client at the tips, Wi-fi has the centralized controller and the remote AP's, and the Firewall, which also has its centralized security rules and where the ideas of centralizing the data stream came, based on Sane and Ethane.
