US Patent 7099865 Method and arrangement in a distributed system

A method and arrangement in a distributed system for synchronizing configuring data at a receiving unit with corresponding source configuring data. The configuring data and the source configuring data are arranged in one or preferably several groups of data. Reference checksums are calculated (201) for each data group. The receiving unit determines (202) whether the content in each data group of the configuring data at the receiving unit matches the corresponding reference checksum. The receiving unit requests (203) the source unit to transfer copies to the receiving unit of the source configuring data in those data groups for which a mismatch is detected. The requested data is downloaded (204) from the source unit to the receiving unit.
