ABSTRACT:
A method and apparatus for providing loop coherency between a multiplicity of nodes. The disclosed technique and apparatus utilize a primary loop for nominal data communications and a normally unutilized secondary loop. A loop coherency circuit detects a loop incoherency condition which results in a interruption of the primary loop. The loop coherency circuit reroutes the flow of data to a secondary loop segment and back to a primary loop segment to provide a continuous coherent arbitrated loop.
