Rediseño de la Infraestructura de Red y Comunicación de la Empresa Digitec S.A

Abstract

Abstract: The research work addresses the redesign of the network infrastructure of the company Digitec S.A., with more than 20 years of existence, to overcome limitations in speed, security, scalability and operating costs. These deficiencies affect competitiveness in a dynamic technological environment. The current topology lacks segmentation, generating link saturation and security problems, while the structured cabling does not meet international standards and obsolete equipment makes maintenance and updates difficult. The redesign proposal is based on international standards and advanced technologies. The physical architecture includes category 6A structured cabling, fiber optic links and a redundant star topology to reduce single points of failure. As for the logical architecture, segmentation through VLANs is proposed to optimize traffic and reinforce security. Modern devices will also be implemented, such as Cisco Catalyst switches and latest generation routers, which guarantee high capacity and efficiency. Security is key in the research. The company proposes to implement next-generation firewalls, IDS/IPS systems, VPN tunnels with AES-256 encryption, role-based access policies, and monitoring mechanisms to mitigate threats in real time. Operationally, a connection of up to 10 Gbps, reduced downtime, and centralized management are expected. Although the initial investment is considerable, a decrease in operating costs and compatibility with emerging technologies such as IoT, 5G, and SDN networks are projected, positioning Digitec to face future challenges.
