Exploiting System Diversity in Peer-to-Peer Publish-Subscribe Systems
… within a particular class of peer-to-peer publish-subscribe systems. We show that by directly addressing interest and network diversity as a first class design principle, the scale and performance of such systems can be improved. This thesis makes four major contributions. Firstly, we …

Replication-based Load Balancing in Distributed Content-Based Publish /Subscribe Systems
In recent years, content-based Publish/Subscribe (pub/sub) has become a popular paradigm to decouple content producers and consumers for Internet-scale content services. Many real applications show that the content workloads frequently follow very skewed distribution, and incur unbalanced …

XSiena: The Content-Based Publish/Subscribe System
… networks so have the decoupling properties of publish/subscribe systems revolutionized the way we look at networking in the context of large scale distributed systems. The decoupling of the components of publish/subscribe systems in time, space and synchronization has created an appealing …

Unifying Databases and Internet-Scale Publish/Subscribe
… push technology has long been the goal of publish/subscribe systems, which proactively push updates (events) to users with matching interests (expressed as subscriptions). The push model is better suited for ensuring scalability and timely delivery of updates, important in many application …
