A self-organizing crash-resilient topology management system for content-based publish/subscribe

by R. Baldoni, R. Beraldi, L. Querzoni, A. Virgillito - 3rd International Workshop on Distributed Event-Based Systems (DEBS’04 , 2004
"... Content-based routing realized through static networks of brokers usually exhibit nice performance when subscribers with similar interest are physically close to each other (e.g. in the same LAN, domain or in the same geographical area) and connected to a broker which is also nearby. If these subscr ..."

. If these subscribers are dispersed on the Internet, benefits of such routing strategy significantly decrease. In this paper we present a Topology Management System (TMS), a component of a content-based pub/sub broker. The aim of a TMS is to mask dynamic changes of the brokers’ topology to the content-based routing

2012 32nd IEEE International Conference on Distributed Computing Systems Total Order in Content-Based Publish/Subscribe Systems ‡

by Kaiwen Zhang, Vinod Muthusamy, Hans-arno Jacobsen
"... Abstract—Total ordering is a messaging guarantee increasingly required of content-based pub/sub systems, which are traditionally focused on performance. The main challenge is the uniform ordering of streams of publications from multiple publishers within an overlay broker network to be delivered to ..."

Elastic Scaling of a High-Throughput Content-Based Publish/Subscribe Engine

by unknown authors
"... ning as a service on cloud environments offer simplicity and flexibility for composing distributed applications. Provisioning them appropriately is however challenging. The amount of stored subscriptions and incoming publications varies over time, and the computational cost depends on the nature of ..."

pub/sub service running in a cloud environment. In this paper, we present the design and evaluation of an elastic content-based pub/sub system: E-STREAMHUB. Specific contributions of this paper include: (1) a mechanism for dynamic scaling, both out and in, of stateful and stateless pub/sub operators

Matching Events in a Content-based Subscription System

by Marcos K. Aguilera , Robert E. Strom, Daniel C. Sturman, Mark Astley, Tushar D. Chandra , 2003
"... Content-based subscription systems are an emerging alternative to traditional publish-subscribe systems, because they permit more flexible subscriptions along multiple dimensions. In these systems, each subscription is a predicate which may test arbitrary attributes within an event. However, the mat ..."
Abstract - Cited by 303 (8 self) - Add to MetaCart
, the matching problem for content-based systems --- determining for each event the subset of all subscriptions whose predicates match the event --- is still an open problem. We present an efficient, scalable solution to the matching problem. Our solution has an expected time complexity that is sub

Distributed Event Aggregation for Content-based Publish/Subscribe Systems

by Navneet Kumar Pandey, Kaiwen Zhang, Stéphane Weiss, Hans-arno Jacobsen, Roman Vitenberg - In DEBS , 2014
"... Modern data-intensive applications handling massive event streams such as real-time traffic monitoring require support for both rich data filtering and aggregation. While the pub/sub communication paradigm provides an effective solution for the sought semantic di-versity of event filtering, the even ..."

aggregation over a range of time-based aggrega-tion window semantics in a content-based pub/sub system. In order to eschew the need to disseminate a large number of publications to subscribers, we strive to distribute the aggregation computation within the pub/sub overlay network. By enriching the pub/sub lan

Delta: Scalable Data Dissemination under Capacity Constraints ∗

by Konstantinos Karanasos, Asterios Katsifodimos, Inria Saclay, Ioana Manolescu, Inria Saclay
"... In content-based publish-subscribe (pub/sub) systems, users express their interests as queries over a stream of publications. Scaling up content-based pub/sub to very large numbers of subscriptions is challenging: users are interested in low latency, that is, getting subscription results fast, while ..."
