Abstract

It is well known that the consensus problem can be solved in a distributed system if, after some time T_S, no process fails and there is some upper bound 驴 on how long it takes to deliver a message. We know of no existing algorithm that guarantees consensus among N processes before time T_S + O(N驴). We show that consensus can be achieved by time T_S + O(驴).
