[en] Internet Coordinate Systems (ICS) provide easy and practical latency
predictions in the Internet. However, peer dynamics (i.e, churn), which is an in-
herent property of peer-to-peer (P2P) systems, affects the accuracy of such sys-
tems. This paper addresses the problem of churn in an ICS without landmarks,
like Vivaldi. We propose a framework to assess the robustness of such an ICS in
the presence of churn, and evaluate two models for handling churn. The key idea
is to reactively recover lost neighbours, either by picking new nodes at random, or
by selecting a new one among the node’s two-hop neighbours, while maintaining
high reliability and low communication overhead. We then show by simulations
that our models mitigate the impact of churn, and lead to a good accuracy com-
pared to an instance of an ICS running without churn.
