Failure detectors for large-scale distributed systems

This paper discusses the problem of implementing a scalable failure detection service for Grid systems. More specifically, traditional implementations of failure detectors are often tuned for running over local networks and fail to address some important problems found in wide-area distributed systems, such as Grid systems. We identify some of the most important problems raised in the context of Grids. We then survey recent propositions that can help in solving some of these problems.
