Abstract The article presents a research of loss probability in various structures of elastic optical network nodes. To conduct the research, an elastic optical networks simulator, which enables to determine loss probabilities of switching network nodes of any structure, was implemented. The simulator is able to offer network traffic composed of Erlang, Engset, and Pascal traffic streams, specified with input parameters. The article includes topics within the realm of elastic optical networks, provides a description of algorithms implemented in the simulator, its input data and parameters, describes the structures of the examined switching network nodes, and presents research results for individual structures and systems. The studies were conducted on practically utilized switching network node structures like Banyan, Baseline, and Omega and Clos switching network nodes.
