Reliability is an important research topic of distributed systems. To achieve fault-tolerance in the distributed systems, healthy processors need to reach a common agreement before performing certain special tasks, even if faults exist in many ...
We introduce Hierarchical Consensus, an approach to generalizing consensus that allows us to scale groups beyond a handful of nodes, across wide areas. Hierarchical Consensus increases the availability of consensus groups by partitioning the decision ...
Generally, the task in a distributed system must achieve an agreement. It requires a set of processors to agree on a common value even if some components are corrupted. There are significant studies on this agreement problem in a regularized network ...
