Efficient Filtering and Routing in a Scalable XML-Based Publish-Subscribe System

This paper introduces YAK – a scalable contentbased publish-subscribe system. YAK employs XML documents and expressive XPath queries as the publication and subscription model. To achieve high scalability, it combines the advantages of content routing in existing publish-subscribe systems and the efficient query indexing technique in the context of XML filtering. The filtering and routing strate...

XlPPX: A Lightweight Framework for Privacy Preserving P2P XML Databases in Very Large Publish-Subscribe Systems

The problem of supporting privacy preservation of XML databases within very large publish-subscribe systems is rapidly gaining interest for both academic and industrial research. It becomes even more challenging when XML data are managed and delivered according to the P2P paradigm, since malicious accesses and unpredictable attacks could take advantage from the totally-decentralized and untrust...

Approximative filtering of XML documents in a publish/subscribe system

Publish/subscribe systems filter published documents and inform their subscribers about documents matching their interests. Recent systems have focussed on documents or messages sent in XML format. Subscribers have to be familiar with the underlying XML format to create meaningful subscriptions. A service might support several providers with slightly differing formats, e.g., several publishers ...

Hardware Architecture of an XML/XPath Broker/Router for Content-Based Publish/Subscribe Data Dissemination Systems

The dissemination of various types of data faces ongoing challenges with the growing need of accessing manifold information. Since the interest in content is what drives data networks, some new technologies and thoughts attempt to cope with these challenges by developing content-based rather than address-based architectures. The Publish/Subscribe paradigm can be a promising approach toward cont...
