Abstract:

We study decision protocols in a model that closely approximates ``real'' distributed systems. Our results show how the weakest failure detector and associated consensus algorithm can be adapted to a network in which omission failures can occur during periods when processes suspect one-another as faulty. For protocols in which a majority subset of the participants can reach decisions on behalf of the system as a whole, we also characterize a series of stages that necessarily arise during execution.
