Journal ArticleDOI
The many faces of publish/subscribe
TL;DR: This paper factors out the common denominator underlying these variants: full decoupling of the communicating entities in time, space, and synchronization to better identify commonalities and divergences with traditional interaction paradigms.
Proceedings Article
Machine learning with adversaries: byzantine tolerant gradient descent
TL;DR: Krum is proposed, an aggregation rule that satisfies the resilience property of the aggregation rule capturing the basic requirements to guarantee convergence despite f Byzantine workers, which is argued to be the first provably Byzantine-resilient algorithm for distributed SGD.
Journal ArticleDOI
Gossip-based peer sampling
TL;DR: This paper presents a generic framework to implement a peer-sampling service in a decentralized manner by constructing and maintaining dynamic unstructured overlays through gossiping membership information itself, which generalizes existing approaches and makes it easy to discover new ones.
Journal ArticleDOI
Epidemic information dissemination in distributed systems
TL;DR: Four key problems: membership maintenance, network awareness, buffer management,buffer management, and message filtering are described and some preliminary approaches to address them are suggested.
Journal ArticleDOI
Lightweight probabilistic broadcast
TL;DR: This paper presents lightweight probabilistic broadcast (lpbcast), a novel gossip-based broadcast algorithm, which complements the inherent throughput scalability of traditional probabilism broadcast algorithms with a scalable memory management technique.
