Abstract
This paper presents a distributed mobile storage sys-tem designed for storage elements connected by a network of non-uniform quality. Flexible data placement iscrucial, and it leads to challenges for locating data and keeping it consistent. Our system employs a location-and topology-sensitive multicast-like solution for locating data, lazy peer-to-peer propagation of invalidationinformation for ensuring consistency, and a distributed snapshot mechanism for supporting sharing. The com-bination of these mechanisms allows a user to make the most of what a non-uniform network has to offer in termsof gaining fast access to fresh data, without incurring the foreground penalty of keeping distributed elements on aweak network consistent.
