Abstract:
The ability of tracking the locations of distributed objects and maintaining cache coherence when they change is crucial for many applications. In this paper, we propose an object tracking system that supports strong coherence semantics and can exploit its awareness of network topology. The network-awareness is especially beneficial in a wide area network where the system's ability of confining routing messages to a smallest possible locality is important. Experiments with a deployment of the system on a real-world Internet overlay show substantial benefits of the system compared to existing approaches.
