Políticas de QoS en redes empresariales para el análisis de rendimiento, en entornos convencionales y SDN.

Abstract

The objective of the titling work was to analyze the performance generated by the allocation of QoS policies, between conventional network environments and SDN, in an enterprise network. This study gives relevance to the technology of programmable networks as an alternative for physical network infrastructures, in order to analyze the behavior of this architecture in real scenarios. Open Flow allows the separation between the control plane and the data plane, allowing flexibility in the development of new software alternatives that run in the control plane. The process consists of the implementation of the scenarios in two environments such as: SDN and conventional, to then assign QoS policies in each of them; after what traffic will be injected into the network using the D-ITG application, to emulate the behavior of a business network node. Then, through measuring tools, the QoS parameters such as bandwidth, latency, jitter and packet loss will be evaluated. Finally, the analysis of the results will be carried out using the T-Student statistical method. Starting from the statistical results, according to the study parameters; in the server we find a difference of: bandwidth 9.12%, latency 5.86%, jitter 1.02% and packet loss 8.7%. In relation to the parameters in the client we find a difference of: width band 6.44% latency 1.52%, jitter 6.28%, packet loss with 6.92%. It is concluded that when applying Qos policies in both scenarios in both the conventional scenario and the SDN, it does not present a significant difference in both the server and the client. As a proposal, I develop a methodological guide, which includes the considerations that should be applied as a result of the test performed.
