Exploiting System Diversity in Peer-to-Peer Publish -Subscribe Systems

111 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2009.Fourthly, the systems described in this thesis have been comprehensively evaluated via both PlanetLab deployment and simulation. Our deployments used up to 400 PlanetLab servers world-wide. Our largest simulations model 10, 000 nodes. Our experimental methodology is constructed using an extensive amount of real-world traces. For instance, to evaluate Rappel using realistic user subscriptions, we gathered the subscription profiles of 1.8 million LiveJournal users over six months. The evaluation presented in this thesis also makes use of the following previously collected traces: Internet topology, end-to-end latency fluctuations between PlanetLab nodes, bandwidth availability between PlanetLab nodes, and end user churn observed in peer-to-peer file sharing applications.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
