Abstract

The object of this study is an access node based on IP-PBX (Internet Protocol Private Branch Exchange) technology as part of a fixed network infrastructure. Unified communications is being implemented, facilitating comprehensive communication and collaboration. Specifically, it integrates voice, video, instant messaging, presence information, email, and document management onto a single platform. Companies across various sectors are investing in IP-PBXs to improve operational efficiency. IP-PBX telecommunications systems deliver voice and multimedia services over an Internet Protocol data network. They replace traditional circuit-switched and time-division multiplexing (TDM) PBX systems by using packet-switched networks and converging voice and data communications into a single infrastructure. This convergence offers significant advantages in terms of cost, scalability, management, and feature integration. Subject of the research: algorithms for distributing node bandwidth between serviced information flows. IP PBXs in corporate communications networks provide communications over existing data networks. Beyond simple cost savings, these systems lay the foundation for the development of unified communications (UC), which integrate disparate communication tools for services such as voice, video conferencing, instant messaging, and email into a single platform. This article presents an approach to studying the operation of a fixed-line node in the context of the transition to unified IP solutions. Various options for the combined transmission of traffic types such as voice and document flow files are discussed. A mechanism for priority resource allocation with a spillover effect is proposed. In this case, voice messages rejected in the main resource segment can be redirected (spilled) to an additional segment used together with file traffic. This approach reduces the overall probability of voice call loss. The negative impact of document flow will affect a small portion of voice traffic. The complex dynamics of flow interactions requires in-depth mathematical analysis.
