Revisiting simultaneous consensus with crash failures

Yoram Moses, Michel Raynal
2009 Journal of Parallel and Distributed Computing  
The agreement requirement is captured by the consensus problem that is one of the most important problems of fault-tolerant distributed computing.  ...  If the processes defining a computation have never to agree, that computation is actually made up of a set of independent computations, and consequently is not an inherently distributed computation.  ...  This optimality proof is established in [3] from the theory of distributed (implicit) knowledge and common knowledge (and the way distributed knowledge becomes common knowledge in a distributed system  ...

Brief Announcement: Revisiting Consensus Protocols through Wait-Free Parallelization

Suyash Gupta, Jelle Hellings, Mohammad Sadoghi, Michael Wagner
2019 International Symposium on Distributed Computing  
In this brief announcement, we propose a protocol-agnostic approach to improve the design of primarybackup consensus protocols.  ...  At the core of our approach is a novel wait-free design of running several instances of the underlying consensus protocol in parallel.  ...  The replica coordinates a single consensus round among m instances of some consensus protocol. Each instance yields a consensus decision.  ...

Coracle

Heidi Howard, Jon Crowcroft
2015 Proceedings of the 2015 ACM Conference on Special Interest Group on Data Communication - SIGCOMM '15  
Distributed consensus is fundamental in distributed systems for achieving fault-tolerance.  ...  To illustrate this problem, we developed Coracle, a tool for evaluating distributed consensus algorithms in settings that more accurately represent realistic deployments.  ...  SIGCOMM Paxos [2] has been synonymous with distributed consensus for over a decade.  ...
