Tight Bounds on Channel Reliability via Generalized Quorum Systems (Extended Version)
Alejandro Naser-Pastoriza, Gregory Chockler, Alexey Gotsman +1
Communication channel failures are a major concern for the developers of modern fault-tolerant systems. However, while tight bounds for process failures are well-established, exten…

Vertical Atomic Broadcast and Passive Replication (Extended Version)
Manuel Bravo, Gregory Chockler, Alexey Gotsman +2
Atomic broadcast is a reliable communication abstraction ensuring that all processes deliver the same set of messages in a common global order. It is a fundamental building block f…

Fault-Tolerant Computing with Unreliable Channels (Extended Version)
Alejandro Naser-Pastoriza, Gregory Chockler, Alexey Gotsman
We study implementations of basic fault-tolerant primitives, such as consensus and registers, in message-passing systems subject to process crashes and a broad range of communicati…
