Afegir etiqueta | Sumari: | This research project is focused on the analysis of the performance of architectures based on software-defined networks and TCP / IP architecture. Software-defined networks (SDN) are a set of highly efficient, scalable, programmable networks, with great speed and ability to manage network resources. In this project, it is first proposed to identify and select protocols, controllers and emulation tools that are currently used in SDN networks. It is proposed to design and implement scenarios for tests based on evaluation metrics. In total, four scenarios are implemented using the Mininet and GNS3 emulators, the first one measures the bandwidth that each network can support using Jperf software. The second scenario consists of carrying out tests of sending packages to measure the minimum, average and maximum latency that the network may have, in addition the Jitter or packet variation is also measured. In the third scenario, the transmission of a video stream between two hosts using a server is performed, this scenario was implemented in GNS3. The fourth scenario is similar to scenario two, the same procedure is used to measure latency and Jitter but here a hybrid topology, SDN and TCP / IP is compared. It should be noted that the code for comparing scenario two and four was performed in RStudio software, which uses R programming language and is a powerful statistical analyzer. Finally, this research project is concluded with the results, it was possible to choose the tools that best adapted to the project, in this case the OpenDayLight controller, the OpenFlow protocol and the Mininet and GNS3 emulators. In the first scenario SDN obtained almost twice the capacity of TCP / IP to handle UDP traffic. In the second scenario the latencies and Jitter were statistically equal in SDN and TCP / IP. The third scenario gave favorable results for SDN, because the amount of data transmitted remained above the transmission threshold, causing the video to have no quality losses compared to TCP / IP where there were losses. In the fourth scenario the topology that performed better in terms of latencies and Jitter was SDN, followed by the hybrid and TCP / IP. |
