METHODOLOGY FOR FORMING INTEGRAL INDICATORS OF NETWORK CONNECTION QUALITY IN PACKET-SWITCHED NETWORKS

DOI: 10.31673/2786-8362.2025.016443

Abstract

The article addresses quality assurance in packetswitched telecommunication systems. Growing network traffic and higher QoS demands challenge
operators with the complexity of comprehensively evaluating network connections across multiple
parameters (delay, packet loss, error rate, jitter).
The research analyzes existing telecommunications studies and ITU-T recommendations Y.1540,
Y.1564, and Y.1731, which define IP network quality indicators. Current evaluation methods, while
effective, often lack assessment integrity, necessitating integral quality indicators.
The study aims to create integral indicator models accounting for synergistic relationships between
network performance parameters. It develops indicators including throughput ratio (TR), priority queue
quality factor (PQF), non-priority queue quality factor (NQF), and network connection quality factor
(NCQF). Additionally, it proposes a "fault tree analysis" model to analyze performance deterioration
causes.
These findings have practical applications in real-time monitoring, fault diagnosis, architecture
optimization, and user need adaptation. The methodology offers flexibility and versatility for different
network types and services, improving assessment accuracy and operational efficiency. This creates a
foundation for more reliable, adaptive telecommunication systems meeting modern requirements.
Keywords: telecommunication networks, quality of network connections, integral indicators, network
performance, delay, jitter, error rate, QoS, interconnection model, throughput, network monitoring, network
optimisation, packet switching
