The authors describe the design and analysis of a fiber-optic ring local computer network using a priority-oriented reservation method as the medium access control (MAC) protocol. Using the proposed approach, any station of any priority can be placed anywhere on the ring without degrading performance considerably. A performance model is presented as well as a comparison with well-known MAC protocols. Performance results show that this protocol is efficient in applications where high volumes of data must be transmitted as quickly as possible. This is the case for applications such as video, high-resolution graphics, and computer room networks.
