Supporting application-specific resolution in an optimistically replicated file system
Proceedings of IEEE 4th Workshop on Workstation Operating Systems. WWOS-III
Preserved Fulltext
In this position paper we describe an interface to incorporate application-specific knowledge for conflict resolution in an optimistically replicated file system. ...
This allows the system to make conflict resolution transparent to the user, thus improving the usability of optimistic replication. ...
Motivation The viability of optimistic replication strategies in providing high availability has been demonstrated by systems like Coda [5] and Ficus [2] . ...
