The design of an optical image guide network for distributed multiprocessing is described. The network supports multiple high bandwidth rings between workstations over distances of 10s of meters. Traditionally, error and flow control functions for multiprocessor networks are implemented in custom high speed electronic Application Specific Integrated Circuits which are physically removed from the interconnect's physical layer. In this paper, we consider migrating these functions directly into the optoelectronic physical layer, yielding an 'Intelligent Optical Network'. Conventional error control protocols are infeasible with dense bit parallel optical systems based on image guides since they require excessive amounts of hardware. The designs of efficient error and flow control protocols for such networks are proposed and analyzed. The key blocks of the protocols have been designed, fabricated and demonstrated in 0.8 micron and 0.5 micron CMOS/SEED devices. The protocols require significantly less hardware then alternative schemes, and CMOS/VCSEL devices supporting these protocols are scalable to very high bandwidths, i.e., 10s of Terabits per second.
