Implementación de un balanaceador de carga de salida a internet basado en un servidor linux.

Abstract

The purpose of this work is to implement an outbound load balancer to the Internet based on a Linux server, which allows balancing the traffic of a local area network (LAN), when there are two Internet connections. This is done by implementing a server, simulated in the Emulated Virtual Environment Next Generation (EVE-NG) software, which has Ubuntu Server 22.04 as operating system to place on it the necessary modules to perform the load balancing of the incoming and outgoing traffic of the two Internet connections. The load balancer also has a "weight" functionality, through which ratios or percentages of desired traffic are assigned to each line and a failover system, for the detection and correction of operation in case of connectivity failures. The first section presents, in a linear fashion, the plan of objectives to be met and the scope of the project, as well as the basic concepts required to understand the subject, together with the topics to be covered that are mentioned in the rest of the document. Section two establishes the methodology, or the steps followed for the conformation of the project, describing in a linear, clear, and concise manner the steps followed for its achievement. Section three describes how the technical requirements were established and through them the necessary components for the project were identified. Next, it is described how the software and hardware to be used were determined, and then, the design and subsequent implementation are described. The final section contains the conclusions and recommendations obtained from the achievement of the objectives, implementation and testing of the project, as well as the bibliographic sources of the applied knowledge and related annexes.
