Abstract

The article is focused on the analysis of integrated models that ensure the uninterrupted operation of telecommunication systems in the financial sector, a sphere marked by geographically distributed assets and an especially high sensitivity to any communication failures. Under conditions of deepening economic digitalization and a substantial rise in infrastructure downtime costs, which became particularly visible in 2022-2023 for large banking institutions, the task of strengthening the resilience of the network environment moves beyond a narrowly technical domain and acquires an openly strategic character. The study is aimed at systematizing the existing approaches to the design of fault-tolerant networks and at evaluating the effectiveness of combining engineering solutions at the physical layer with software-defined traffic management mechanisms. The methodological foundation includes a comparative analysis of fiber-optic line deployment technologies, a systematic review of the international standards ISO 22301 and TIA-942, and an examination of practical cases of infrastructure modernization in systemically important banking structures. The analysis conducted showed that the use of underground cable routes in combination with SD-WAN and SASE technologies makes it possible to achieve a service availability level of 99.99% while simultaneously reducing the total cost of ownership by 15-30%. The results of the study confirm the validity of the proposition that the minimization of operational risks in the banking environment is possible only through a coordinated combination of the physical protection of infrastructure and the intelligent orchestration of network processes. The conclusions presented possess practical significance for senior bank management, heads of IT divisions, and specialists responsible for business continuity.
