ABSTRACT:
Syndrome values are employed as a mechanism for synchronization and consistency in a distributed data processing environment. Syndromes are computed for local resources on individual peer nodes and an aggregate syndrome is computed from the individual syndromes. This renders it easy to determine not only that a change has occurred but it also makes it easy to determine which node needs to be updated and thus avoids the needless transmission of updated contents.
