We consider scheduling distributed real-time tasks in unreliable (e.g., those with arbitrary node and network failures) and untrustworthy systems (e.g., those with Byzantine node ...

Traditional agreement-based Byzantine fault-tolerant (BFT) systems process all requests on all replicas to ensure consistency. In addition to the overhead for BFT protocol and sta...
This paper introduces dual-quorum replication, a novel data replication algorithm designed to support Internet edge services. Dual-quorum replication combines volume leases and qu...
