Abstract

A system and methods for synchronizing information in datasets via a communication medium are provided that are suitable for synchronizing even across communication mediums that are susceptible to high latency, non-FIFO (non-First-In-First-Out) delivery order, or other adverse characteristics. According to an aspect of the invention, in an information processing system, a method for synchronizing a first dataset with at least a second dataset via a communication medium includes a step of storing information that is indicative of a first version of user data of the first dataset, wherein the first version has been involved in prior use for synchronizing with the second dataset. The method further includes steps of identifying a change in the second dataset that is new relative to the first version of the user data of the first dataset; via the communication medium, communicating the change in the second dataset and indicating the first version based on the stored information; determining whether user data currently in the first dataset has changed relative to the first version that was indicated in the communicating and indicating step; deciding whether to commit the communicated ch…
