Abstract :
The design of fault-tolerant asynchronous networks has been an unsolved problem. In this paper, necessary and sufficient conditions on state assignments for fault-tolerant asynchronous networks are given. Three design techniques, based on Liu´s 2so - 1 assignment, Friedman et al.´s (2, 2) separating system, and (2so + 1) assignments, are given for fault-tolerant asynchronous networks. The earlier Liu´s upper bound on state variables for USTI assignment for 2so rows is improved to 2so - 2so¿3.
