摘要：The paper discusses the architecture of ring-type OPS (Optical Packet Switching) networkswith QoS management. The electronic-optical nodes of the network enable optical packet switching withinthe ring and electronic buffered interface for a client. The differentiation of the quality of service wasachieved by means of the system of priorities, and thanks to proposed mechanism of priority registers fairaccess to the link was achieved. This enables the network to be used for transporting various classes ofdata with varying requirements as to the quality of service. Simulation trials have been conducted and ananalytical model for this type of network has been proposed.
