Systems and methods are disclosed herein for computing, applying, and displaying document deltas. Snapshots are stored of documents, and the stored snapshots are flattened. Deltas of the flattened snapshots are computed. The deltas are converted to representations of changes in the document by inverting the flattening. The representations of changes are displayed to a user via a feed. Users of the systems and methods can accept, reject, and comment on the changes.

System and method for computing, applying, and displaying document deltas

A method includes receiving streaming media data having a media frame and a frame index referencing the media frame; allocating a frame budget for an output media frame by estimating a frame size of the output media frame based on the frame index; generating the output media frame in real-time by processing the media frame based on first processing parameters and, if the allocated frame budget is greater than a frame size of the processed media frame, padding the processed media frame; and providing the output media frame.

A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that 'virtualizes' a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

A single- or multi-protocol buffering proxy accepts communication option negotiation commands from a client before establishing a connection between the client and a host. The proxy negotiates a limited set of options with the client before the connection is established and buffers (accepts and temporarily stores without responding to) other option negotiation commands from the client. The proxy accepts credentials from a user and establishes, or denies the connection based on the credentials. If the connection is established, the proxy buffers option negotiation commands sent by the host. After the proxy logs in to the host on behalf of the user or the user logs in directly, the proxy sends each party's buffered option negotiation commands to the other party, ceases buffering option negotiation commands and enters a 'pass-through' mode, in which the proxy passes characters and commands between the parties until the session ends. The proxy uses the credentials to allow or deny subsequent connection requests, without re-prompting for credentials.

An architecture, including a file-level protocol, for supporting sparse volumes on a storage system is provided. The file-level protocol provides coherency checking for use in retrieving data stored on a backing store remote from a storage system.

Architecture for supporting sparse volumes

In one embodiment, the invention provides an apparatus for caching data in a network, with the apparatus including a proxy cache configured to receive request for an object from a client and to fetch data blocks from a server. The proxy cache may be configured to cache the data blocks in a hierarchical relationship within the object. The object may be, for example, a data file or a directory. The data blocks that are cached in the proxy cache define an active data set which is based upon a request from a client.

Network caching device including translation mechanism to provide indirection between client-side object handles and server-side object handles

In an embodiment, a method to provide data consistency in a storage system, includes: providing, by a server to a proxy cache, a lock associated with a delegated file in the server; in response to a write request from a client, modifying data in a cached copy of the delegated file in the proxy cache; revoking, by the server, the lock associated with the delegated file, in response to a request from another device to access the delegated file so that the delegated file is now a formerly delegated file; and writing the modified data to the formerly delegated file in the server to update the formerly delegated file; and permitting access to the formerly delegated file by the another device.

Apparatus and method for data consistency in a proxy cache

In one embodiment, the invention provides a method of transforming a request from a client to a proxy cache, the method comprising: receiving a request from a client, where the request is based upon a first open standard protocol; and translating the request from the first open standard protocol into a second open standard protocol at a file system level; and transmitting the request in the second open standard protocol to a server.

Apparatus and method for processing data in a network

In one embodiment, a method of processing data in a network with multiple proxy caches, includes: pushing cached data in a first proxy cache to at least one other proxy cache in a cluster configuration; caching the data from the first proxy cache; and permitting a client to access the data in the at least one other proxy cache in the cluster configuration. In another embodiment, a method of processing data in a network with multiple proxy caches, includes: providing a snapshot replica from a first server to second server; and permitting a proxy cache to access the second server for data in the snapshot replica, in response to a disconnect operation of the first server.
