Sistema de monitoreo para clientes de proveedores de Internet utilizando contratos inteligentes.

Abstract

The project aims to design a monitoring system for Internet service provider customers based on smart contracts, ensuring compliance with Service Level Agreements (SLA). Its purpose is to supervise the service and apply compensations automatically, guaranteeing efficiency and transparency in SLA management. It arises from the need to improve response times to service unavailability and increase trust between providers and users through decentralized technologies. The development involved simulating a network environment using GNS3, recreating the connection to the end customer. The monitoring system was implemented with Zabbix, which generated alerts during periods of unavailability. The collected data, before reaching the blockchain network simulated in Ganache, was processed using Python scripts. The smart contract was deployed with Truffle, automating the SLA stipulations. Additionally, a graphical interface was developed using Node-RED, InfluxDB, and Grafana to present compensations and availability percentages. The tests showed that service availability monitoring is effective and that the compensations established in the SLA were applied automatically. Likewise, the use of blockchain technology provided security and immutability, while the graphical interface offered a user-friendly way to visualize real-time information. Finally, the proposed system significantly optimizes SLA management, ensuring transparency in compliance with its clauses, improving incident response, and enhancing user satisfaction and trust. Keywords: smart contracts, blockchain, SLA, immutability.
