Diseño y simulación de una red de Datacenters basada en topología FAT-TREE en un ambiente de redes definidas por software (SDN).

Abstract

Due to the recent increase of internet users, Internet traffic caused by Data Centers have grown, leading to Internet congestion problems, this brings about major changes in the Data Centers Infrastructure in order to overcome drawbacks and offer good quality services. The objective of this proposal is the design and implementation of a DC network based in Fat-Tree topologies under a Software Defined Networking environment, by establishing a computer-simulated scenario to contribute with the study of existing problems in these DC The Software involved in this project incorporate the use of Open Daylight, a SDN controller was in charge of running the Network Administration, simulated by Mininet software. The D-ITG software was the responsible for generating traffic with statistical behavior. In order to test this scenario, network metrics based on invariants were chosen and the theoretical results obtained keep similarity with the results obtained through the experimentation in approximate conditions to a real DC. This project lays the groundwork for future researches and can be used as a tool for testing new DC solutions proposals with different topologies or network sizes.
