  • Synchronous peer-to-peer multipoint database synchronization
    Patent number: 7966285
    Abstract: A method of synchronizing databases between multiple users in a peer-to-peer network is disclosed. The method comprises extracting changes from a source database of one of the users. Next, the changes are compressed and sent to the other users in the peer-to-peer network in parallel. Finally, the changes are decompressed and replicated on the database of each of the other users. In this respect, the databases of the other users will contain all changes from the source database.
    Type: Grant

  • System and method for synchronous peer-to-peer appointment scheduling facilitation
    Publication number: 20030130882
    Abstract: In accordance with the present invention there is provided a method for serverless calendar sharing that allows free/busy time to be exchanged, viewed and new appointments scheduled between computing devices sharing a common calendar format without the use of a server and using a peer-to-peer network. An interval for the meeting/appointment is selected by an initiating device, and a request is sent out to participant devices in the peer-to-peer network for a set of free and busy time slots. A time slot for a meeting is considered free if it is correspondingly free in all participating responses, otherwise it is busy. The aggregate busy time is resolved using an efficient algorithm that is easily computed on low-compute-power devices such as handhelds.
