The last paper commented on the Friday paper seminar, which just came back after the holidays, was Large-Scale Newscast Computing on the Internet, by Jelasity et al.; this paper describes a so-called gossip protocol for maintaining an overlay network and disseminating information over it. The protocol is really simple: each node keeps a cache, and interchanges it upon being contacted by other nodes. This keeps the number of connections small, and creates a small-world network, allowing for easy and fast dissemination of information.
We have been using this kind of protocol for evolutionary computation, and will keep doing so in our current grants. All in all, an useful and interesting paper.
