Difference Based Content Networking (DBCN) uses diffs between versions to optimize the amount of data sent on the network for version updates of data files. This paper describes several variations on DBCN based on binary diffs, content object diffs, byte offset diffs, and chunk catalog diffs. Existing CCNx versioning methods use total replication of data file bytes between versions, resulting in poor efficiency in data transfer.
