Pub-sub is a paradigm for asynchronous communication that is commonly
used in a great variety of industrial applications, such as news
tickers, delivery of financial data, Military applications, and many
others. While client-server communication still remains the
prevailing implementation paradigm for pub-sub, its limitations for
large-scale applications are widely recognized. Major industrial
players such as Google and Tibco are recognizing the potential of
cooperative overlays and starting to replace legacy centralized
architectures. However, the lack of adequate technologies hinders this
industrial shift.
In this talk, I will consider the problem of designing a scalable
overlay network to support decentralized topic-based pub-sub
communication. I will present the overview of the state-of-the-art in
this area and our recent results, both analytical and experimental,
based on the ICDCS'10 and ICDCS'11 publications. These results (a)
improve the runtime complexity of existing algorithms, (b) address the
challenge of incremental construction by introducing the overlay join
problem, and (c) allow for parallelized overlay construction while
retaining the high quality of the centralized design.
