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.
