Análisis de las arquitecturas de conexión de Redes Privadas Virtuales VPNS para la transmisión de videoconferencia.

Abstract

This research aimed to analyze the connection architecture Virtual Private Network (VPNs) in video conferencing transmission which will allow determining which one is the best to be implemented. This was the hypothesis: “IPSec is the best protocol which should be implanted in architecture VPN in order to better performance of video conferencing transmission”. It was used the analysis of variance ANOVA of a factor through the test Post hoc, HDS Tukey, in comparison of architecture with lower significant level (0.05). Indicators used were latency, jitter, bandwidth, percentage of datagrams received from thirty samples of servers with open source such as: OpenVPN SSL, OpenSSH, OpenSwan IPSec, with GNS3 with cisco for SSL, SSH, IPSec, videoconferencing was conducted through Linphone software. Based on the analysis carried out by the means of ANOVA it was determined the protocol with the best performance in VPN was the open source OpenSSH which has (0.034) latency, (0.00) jitter, (0.00) datagrams received. Three up to four indicators have lower significant level which refused the hypothesis proposed in this study. IPSec is the appropriate for Cisco devices with data gotten from GNS3 simulator according to ANOVA test which has (0.03) latency, (0.00) jitter, (0.00) bandwidth which confirms the hypothesis proposed in this study. Open source allows creating VPN al low cost, so this software is implement in a computer without many requirements of CPU about Linux including Centos. It is recommended the use of open source because of the cost of equipment.
