About

Oleg Zayats is a researcher specializing in queueing theory, stochastic modeling, and the application of mathematical models to real-world communication and space systems. His work focuses on retrial queueing systems and their use in optimizing data transmission under constraints, particularly in environments with limited buffers and multiple traffic flows. A key contribution is his modeling of a data transmission system for remote robot control from the International Space Station (ISS) using public networks, as detailed in his highly cited 2017 paper on the "Kontur" space experiments. This work introduced a retrial queueing model with two incoming flows, a single service channel, a limited buffer, and a randomized push-out mechanism, addressing the challenge of lost packets in space communication. With 6 citations, this paper has influenced subsequent research in space-based queueing and network reliability. Zayats’s work bridges theoretical queueing models and practical engineering challenges, making his research valuable for students and professionals in telecommunications, space operations, and applied probability.
