Análisis comparativo entre VPN IPSEC y DMVPN (Dynamic Multipoint Virtual Private Network) para mejorar el desempeño de redes privadas sobre internet.

Abstract

The comparative analysis between Virtual Private Network Internet Protocol Security (VPN IPSec) and Virtual Private Network Dynamic Multipoint (DMVPN) was made to improve the performance of private networks over the Internet. The traditional VPN solution is based on IPsec point to point, which does not allow direct communication between each site and depends on the status of its concentrator to ensure the communication. A new technique was evaluated; this eliminates point-to-point connections and enables the convergence of applications. DMVPN analyzed as a solution; that will improve the performance of VPNs over the Internet. A network of one HUB and four SPOKE was implemented for the transmission and evaluation of data, voice and video packages. Analyzed the results of the tests in both scenarios, it obtained that the communication between SPOKES predominated in throwing favorable results with an improvement of 88,8% in the delay, 64,1% in the jitter and 84,9% in the loss of packages. Applying the statistics inference concluded that the DMVPN technique yields better values in the performance indicators of the network that are packet delay, jitter, and lost packets, in the same way, it shows lower dispersion values. As a proposal, a DMVPN implementation guide was developed, including all the considerations that should be applied in the practice product of the tests performed.
