CONFLICT RESOLUTION FOR COLLABORATIVE WORK SYSTEM

摘要

Data objects replicated at multiple computers can be synchronized using synchronization messages exchanged over a network. The synchronization messages include a current operation parameter and a previous operation parameter that are processed to determine how and when the replicated data objects should be manipulated. Th e current operation parameter identifies an operation and associated data to be execut ed at a receiving computer to synchronize the receiving computer's data object. An execution stage parameter is also sent to identify a correct execution timing for the operation. The previous operation parameter identifies a preceding operation executed by the sending computer, an execution stage at which the preceding operation was executed, and the computer first originating the preceding operation (e.g., an identify of a third computer that first initiated the operation). Data in the synchronization message can also indicate a unique priority leve l of the sending computer with respect to the other computers.
