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. WebIn 1985, Fischer, Lynch and Paterson proved that the consensus problem is not solvable in an asynchronous system subject to a single process crash. In 1991,ChandraandTouegshowedthat,byaugmentingthe asynchronoussystem model with a well deÞned unreliable failure detector, consensus becomes solvable. They also
