Abstract: Embodiments of the present invention disclose a document sharing method, system, and device. In the embodiments of the present invention, a document is partitioned by the compere client into at least one page for caching. The method includes: receiving a page notification message, where the page notification message includes an identifier value of the page, and the identifier value is digest information of the page obtained by the compere client by using a digest algorithm; judging, according to the identifier value, whether the page corresponding to the identifier value is already saved; and downloading the page corresponding to the identifier value when the page corresponding to the identifier value is not saved, or not downloading the page when the page corresponding to the identifier value is already saved, which can effectively save bandwidth.

Abstract: This application discloses a storage controller. When running, the storage controller encodes, according to a check matrix, K to-be-coded data chunks obtained from a client, to generate two check chunks. In this way, if any chunk is damaged subsequently, the damaged chunk may be recovered by using the check matrix and an undamaged chunk.
