WebBecause of this, several impossibility results have been derived—see for instance the well-known paper (Fischer, Lynch, & Paterson, 1985). As a consequence of these pessimistic results, many researchers have devoted their time and abilities to understanding how to reformulate the concept of system model in a fine-grained alternative way ...

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. WebThe Fischer-Lynch-Paterson theorem (FLP) says that it is impossible for processes in an asynchronous distributed system to achieve consensus on a binary value when a single process can fail. It is a widely cited theoretical result about network computing. All proofs that I know depend essentially on classical (nonconstructive) logic, although ...
