Applied information technologies in modern computer networks: foundational framework and emerging paradigms

Abstract

The proliferation of digital infrastructure has positioned computer networks as the central nervous system of the modern global economy. This paper explores the domain of Applied Information Technologies (AIT) within computer networks, moving beyond theoretical constructs to focus on their practical implementation and impact. We define AIT in this context as the disciplined application of software, hardware, and protocols to solve real-world problems of data communication, resource management, and service delivery. The article provides a structured analysis of core AIT domains, including Software-Defined Networking (SDN), Network Function Virtualization (NFV), AI- driven network orchestration, and the integration of robust security frameworks. Furthermore, it examines the challenges of scalability, security, and interoperability inherent in these technologies. By synthesizing current implementations and trends, this paper argues that the strategic application of these technologies is not merely an operational enhancement but a critical determinant of organizational agility, resilience, and competitive advantage in an increasingly interconnected world
