Appeal 2007-0663
Application 09/825,661
3. "To describe the exact state of a set of data files, the DRP protocol
uses a data-structure called an index." (§ 2.2.)
4. "An index is a snapshot of the state of a set of files at a particular
moment in time." (Id.)
5. "An index not only describes the hierarchical structure of the files,
but it also describes the version, size, and type of each file." (Id.)
6. "Once [an] initial download is complete, a client can update the
content by downloading a new version of the index, and comparing it against
the previous version of the index." (§ 2.3.)
7. "Because each file entry in the index has a content identifier, the
client can determine which files have changed and so determine the minimal
set of files that need to be downloaded in order to bring the client up-to-
date." (Id.)
8. "Because the client can determine the exact set of files that need to
be downloaded, it is possible to issue multi-file requests to get all the files at
once." (§ 2.4.)
9. "When requesting a file, the client can include the content identifier
in [an] HTTP GET request to the server." (Id.)
