GAMMA-NET: A local computer network coupled by a high speed optical fiber ring bus — system concept and structure

Abstract

The concept and structure of a local computer network are presented for a full scale high performance computer network coupled by a dual 32 Mbps optical fiber ring bus. The design goals of the system are efficient resource sharing and improved RAS. Implementation issues of the system are discussed, focussing on the optical fiber ring bus and the network operating system services. The experimental results also include the processing times for a data link connection/disconnection, the synchronous delay time for a read/write operation matching, and the data transmission speed and efficiency of both the multiplex mode and the burst mode.
