Federating digital contact tracing using structured overlay networks

pFilter: Global Information Filtering and Dissemination Using Structured Overlay Networks

The exponential data growth rate of the Internet makes it increasingly difficult for people to find desired information in a timely fashion. Information filtering and dissemination systems allow users to register persistent queries called user profiles, and notify users when relevant files become available. Existing such systems, however, either are not scalable, or do not support matching of u...

Distributed Hashtable on Pre-structured Overlay Networks

Internet overlay services must adapt to the substrate network topology and link properties to achieve high performance. A common overlay structure management layer is desirable for enhancing the architectural modularity of service design and deployment. For instance, new link probing techniques can be incorporated into the common structure layer such that a large number of overlay services can ...

An Overview of Structured P2P Overlay Networks

A Transactional System for Structured Overlay Networks

We propose a system for executing transactions on top of structured peer-topeer networks. Our system guarantees most properties usually expected from transactions, namely atomicity, independance, and consistency. The system is based on distributed locking, with a fully decentralized management. It avoids deadlocks and starvation by assigning priorities to transactions.

Estimating Churn in Structured P2P Overlay Networks

Structured peer-to-peer (P2P) networks have become an important alternative to the classic client-server architecture. Participating peers can join and leave the system at arbitrary times, a process which is known as churn. Many recent studies revealed that churn is one of the main problems faced by any Distributed Hash Table (DHT). As a countermeasure most DHT protocols have to invest a signif...
