Migración de la red y gestión en la configuración automática de equipos en el ISP grupo Megared

Abstract

The purpose of this research project was to improve the availability of internet service of the Grupo Megared company. A field investigation was conducted, visiting each node of the network and verifying its connections in order to obtain a physical and logical diagram of the network using tools such as Winbox for access to network devices and Microsoft Visio for graphical representation of the network structure. A physical network diagram was then proposed analyzing backup path requirements where 3 Mirotik routers were added in nodes handling high traffic and large number of clients. At the same time, a logical network diagram is proposed taking as reference the growth rate of the wireless sector of the ISP Grupo Megared. This logical diagram has an OSPF dynamic routing configuration, allowing the creation of backup routes. All the network migration and tests of its operation were carried out in the EVE-NG simulator for its simplicity in the configuration of equipment. For the tests, the jperf tool that works with java was used, creating a jperf server in an interface of the border router and a jperf client on the farthest node in the network, obtaining results of latency, throughput and loss of UDP packets which was concluded that the bridge configuration has a packet loss of 1.08% compared to the OSPF configuration which has a packet loss of 0.4% but the OSPF network has a longer response time compared to the bridge network. Finally, the API-REST tool was used for the configuration of computers, where a .py execution script was created. The test is performed assuming that an IP address has been removed from the border router by human error, and that running script.py can reconfigure the removed address.
