发明名称 System for negotiated differential compression
摘要 A system and methods for distributing a new file from a server connected through a network to a client. Rather than downloading an entirely new file from the server, the system makes use of reference files already resident on the client. A new delta file corresponding to a reference file is sent to the client. The client generates the new file by modifying the corresponding reference file according to the change instructions in the new delta file.
