SoftwarePractice and Experience, vol. These systems work very well in environments with few conflicts and their strategy is quite effective for objects with simple semantics e.g. file directories. They have proven the value of semantic conflict detection and resolution. SoftwarePractice and Experience, vol. No context found.
Optimistic replication minimizes the bandwidth and connectivity requirements for performing updates.
However , optimistic replication systems can allow conflicting updates to replicated data items. In client server replication, all updates must be propagated first to a server machine that further propagates them to all clients. Rumor uses a fully distributed, two phase, coordinator free algorithm to ensure that all replicas learn of the garbage collection process and eventually complete it, even though any given set of participants may never be simultaneously present. 3.1 Rumor architecture Rumor needs to manage attributes above and beyond the standard file system attributes, such as version vectors.
