About

Eitan Altman is a leading figure in the field of performance evaluation and control of communication networks, with a particular focus on queueing theory and stochastic optimization. His research addresses fundamental challenges in routing and resource allocation under uncertainty, where he has made pioneering contributions to the optimal control of systems with limited or no buffer capacity. His most-cited work, "Optimal admission, routing and service assignment control: the case of single buffer queues" (2002, 20 citations), tackles the critical problem of maximizing throughput in networks where packets are lost if routed to busy servers, providing rigorous analytical solutions for optimal decision-making. In a related study, "Open-loop routing to M parallel servers with no buffers" (2000, 6 citations), Altman explores routing strategies when the controller lacks real-time server state information, advancing the theory of decentralized control in queueing systems. These contributions have had a lasting impact on the design of efficient, loss-sensitive networks, influencing both theoretical research and practical implementations in telecommunications and data centers. Altman’s work is essential reading for students and researchers interested in the intersection of control theory, operations research, and networking.
