Thomas P Daniell, Robert C Harding Jr, Roger W R Harvey, Sven H H Nauckhoff: Method and apparatus for asynchronous processing of dynamic replication messages. International Business Machines Corporation, Shelly M Beckstrand, R Bruce Brodie, October 28, 1986: US04620276 (31 worldwide citation)

Messages at nodes of a distributed data system are processed asynchronously. Each data atom shared by a pair of nodes is characterized by dipole halves maintained at each node including an access control characteristic, a quality control characteristic, and a pair of rank values. A rank value is a v ...
