Peer to peer Synchronization system and method

A program storage device which performs a method of enabling peer to peer synchronization between members of a synchronization network, the synchronization network being implemented in respect of a predefined synchronization reference area on each network member, the device comprising:

• one or more processors;
• and
• a machine readable medium comprises one or more sequences of instructions, which when executed by the one or more processors, cause:
• detecting on a first member of the synchronization network a change with respect to a data unit within the predefined synchronization reference area, the data unit is associated with a data item of the synchronization network;
• determining a relative path within the predefined synchronization reference area to the data unit associated with the change;
• determining a type of the change;
• obtaining a value calculated based upon a content of the current version of the data item on said first member of the synchronization network;
• if a previous version of the data item exists on said first member of the synchronization network, obtaining a value calculated based upon a content of a data unit that is associated with a previous version of the data item;
• obtaining a current log number for said first member of the synchronization network, the current log number is associated with an incremental count of logs that is updated in connection with a change occurring with respect to a data item of said synchronization network on said first member of the synchronization network;
• generating a log representing the change based upon:
• a current log number on said first member of the synchronization network, said type of change, said relative path, said value corresponding to the content of a current version of the data item, and if a previous version of the data item exists, the value corresponding to the content of the previous version of the data item,
• wherein said generating a log further comprises, in case that the change is associated with implementing on said first member of the synchronization network a different log received from another member of the synchronization network, including in the log representing the change on said first member of the synchronization network a member identifier of said other member of the synchronization network and the number of the different log on said other member of the synchronization network;
• and
• forwarding the log to two or more members of the synchronization network.

• wherein causing the computer to generate a log further comprises, in case that the change is associated with implementing on said first member of the synchronization network a different log received from another member of the synchronization network, including in the log representing the change on said first member of the synchronization network a member identifier of said other member of the synchronization network and the number of the different log on said other member of the synchronization network;
• and
• computer readable program code for causing the computer to forward the log to two or more members of the synchronization network.
