Motivation. Peer-to-peer (P2P) systems are
mostly deployed in heterogeneous environments
with resource availability varying not only across
the nodes but also over time. If any of the shared
computational, storage or network resources are
exhausted, failures and delays occur. The com-
monly used crash-stop failure model assumes that
once a node stops sending messages it never again
resumes. Such failures are trivially detected and
appropriate algorithms are run that maintain the
connectivity and routing efficiency of the P2P over-
lay under continuous arrivals and departures of the
