Extended ring-like communication architecture

Abstract

Various systems and methods for fault-tolerant and otherwise optimized communication, in which a system includes communication nodes connected by wireless data links together forming a ring structure, as well as additional wireless data links operative to partition the ring structure into multiple sub-ring structures. The system is operative to select, per each of the sub-ring structures, one of the wireless data links to remain dormant, thereby effectively creating a certain communication tree structure. The system is further operative, upon detecting a communication problem or inefficiency in any or all of the sub-ring structures, to shut-down, per sub-ring structure detected, the problematic or otherwise inefficient wireless data link, and to reactivate instead the dormant wireless data link, thereby effectively switching to a new communication tree structure, and thus resolving the problem or otherwise improving efficiency.
