WebFischer, Lynch and Paterson [FLP] have shown that in a com pletely asynchronous model, even one failure cannot be tolerated. In this paper we extend their work, identifying several critical system parameters, including various synchronicity conditions, and examine how varying these affects the number of faults which can be tolerated.
