Resumen
La aplicación de un diseño de red que se basa en redundancia de Gateway, aplicado con el protocolo de alta disponibilidad, ya sea CARP o VRRP sobre GNU/Linux ofrece una conexión permanente hacia el internet para equipos de cómputo que se encuentran divididos en dos grupos por tener proveedores de internet diferentes. Para poder seleccionar el protocolo más adecuado se realizó un estudio comparativo mediante un muestreo de variables, con sus respectivos indicadores, y además una comparación de los tiempos medios entre fallos; con el protocolo CARP se crea un grupo de firewall redundantes, dos equipos realizan el filtrado de paquetes, si uno falla el otro se hará cargo de la operación realizada por el servidor de seguridad que falló debido a un problema que pueda tener. Los resultados que se obtienen es una conexión confiable y operativa en su totalidad con los datos y hacia el internet, con tiempos de transición transparentes para el usuario y una percepción casi nula del fallo ocurrido, mediante el análisis de los dos protocolos, llegué a la conclusión de que CARP ofrece más viabilidad y flexibilidad para implantar la solución que se desea, y además los tiempos medios entre fallos se disminuyen en relación a los datos originales con la red actual; Se recomienda antes de plantear los esquemas de solución obtener la mayor información científica sobre el fundamento teórico de los protocolos, con el fin de prevenir problemas en el momento de la aplicación.
The implementation of a network design based on redundancy Gateway, applied to the protocol for high availability, whether CARP and VRRP on GNU / Linux provides a permanent connection to the Internet for computer equipment that are divided into two groups by having different internet providers. In order to select the most suitable protocol a comparative study was conducted by sampling variables, with indicators, and also a comparison of the average time between failures; with CARP protocol it creates a group of redundant firewall, two teams perform packet filtering, if one fails the other will take over the operation performed by the firewall that failed due to problem that may have. The results obtained are reliable and fully operative connection with the data and to the internet, with transparent time to the user and a perceived failure occurred almost no transition, by analyzing the two protocols, I came to the conclusion that CARP offers more practicality and flexibility to implement the desired solution, and also the average time between failures are reduced in relation to the original data with the present network; it is recommended before raising schemes solution to get the most scientific information about the theoretical arguments of the protocols, in order to prevent problems at the time of implementation.
