A fault-tolerant, scalable, low-overhead distributed garbage detection protocol
Marc Shapiro · 2002
The author presents a protocol for the distributed detection of garbage in a distributed system subject to common failures such as lost and duplicated messages, network partition, dismounted disks, and process, site, and disk crashes. The protocol uses only information local to each site, or exchanged between pairs of sites; no global mechanism is necessary. Overhead is low. The protocol is parallel and should scale to extremely large systems.>
