WebWe first state some assumptions underlying our study of agreement algorithms: Failure models Among the n processes in the system, at most f processes can be faulty. A faulty process can behave in any manner allowed by the failure model assumed. The various failure models – fail-stop, send omission and receive omission, and Byzantine failures ... A snapshot algorithm is used to create a consistent snapshot of the global state of a distributed system. Due to the lack of globally shared memory and a global clock, this is not trivially possible.
