Guest talk by Prof. Hans-Arno Jacobsen (University of Toronto) on Thursday February 11 at 14-16 in Exactum CK111.
Title: Flexible Data-centric Networking with the PADRES Publish/Subscribe System
Abstract:
In data-centric networking, data sinks declaratively express information needs, while data sources simply publish information of interest. This paradigm greatly simplifies large-scale distributed application development and eases continued system evolution. The challenge, however, lies in the development of middleware abstractions that support this modus operandi. We argue that publish/subscribe realized as adaptive content-based message routing over general overlay topologies is ideally suited as middleware abstraction for data-centric networking.
In this talk we illustrate the vision of data-centric networking realized through publish/subscribe messaging. We contribute content-based routing protocols to support general overlay topologies, as opposed to traditional tree-based or flooding-based schemes. Among other benefits, our approach enables message routes to adapt to dynamic conditions, such as congestion, failure, or network status and traffic, by choosing among alternate routing paths. We also discuss how to exploit this flexibility for the detection of composite events. This research draws from the open source PADRES publish/subscribe project applied in industry collaborations to business activity monitoring, business process management, monitoring and control of service-level agreements, and enterprise application integration.

Speaker bio:
Hans-Arno Jacobsen is a professor of Electrical and Computer
Engineering and Computer Science at the University of Toronto. He
holds the Bell University Laboratories Chair in Software and he is the
chair of the Computer Engineering Group. His research is focused on
the activities of the Middleware Systems Research Group (msrg.org).
His research aims to ease the development of scalable, reliable, and secure distributed enterprise applications. In pursuit of these objectives, he engages in basic research on event processing, publish/subscribe, service-orientation, aspect-orientation, and green middleware. In research and development engagements with various companies, he pursues projects on business process management, service delivery models, service and infrastructure management, and e-energy.
Selected research projects include the PADRES Events & Services Bus (padres.msrg.org) for effective business process management, the eQoSystem project (eQoSystem.msrg.org) for declarative monitoring and control of SLAs (service level agreements) in enterprise applications and business artifacts, and the AspeCtC (ACC) project (aspeCtC.net) for increasing modularity in systems software and embedded systems.
Arno has served as program committee member of various international conferences, including ICDCS, ICDE, Middleware, SIGMOD, OOPSLA and VLDB. He was the Program Chair of the 5th International Middleware Conference and the General Chair of the Inaugural International Conference on Distributed Event-Based Systems 2007. He is among the initiators of the DEBS (debs.org) conference series and the Event-based.org (event-based.org) research portal. Further information is available from msrg.org.
