A technique for generating component usage statistics involves associating components with blocks of a stream-enabled application. When the streaming application is executed, block requests may be logged by Block ID in a log. The frequency of component use may be estimated by analyzing the block request log with the block associations.

A technique for modifying virtual files involves tracking changes locally. A method according to the technique may include virtually representing a file on, for example, a streaming client, and writing modifications to the virtual file into a diff-file on the streaming client. A system according the technique may include a virtual file associated with a remotely stored file, a diff-file, stored locally, associated with the remotely stored file, and a diff-file integration engine. The diff-file may include local changes to the virtual file. The diff-file integration engine may be capable of combining the virtual file with the diff-file to create a locally modified virtual file.

A technique for streaming from a media device involves enabling a local device to function as a streaming server. An example of a method according to the technique includes inserting a removable storage device that includes programs associated with a streaming application, running one or more of the programs, ensuring that a streaming software player is installed, and executing a streaming-related activity associated with the streaming application. An example of a system according to the technique includes a means for providing a streaming application that expects content to be found on a media drive, a means for intercepting requests for content expected to be found on the media drive, and a means for honoring the requests with content from a different media location.

A technique for determining a data window size allows a set of predicted blocks to be transmitted along with requested blocks. A stream enabled application executing in a virtual execution environment may use the blocks when needed.

Opportunistic block transmission with time constraints

A method for streaming software may include downloading blocks associated with a software title until an executable threshold is reached, initiating execution of the software title, and continuing to download blocks of the software title while the software title is executed. Another method for streaming software may include sending to a client data sufficient for the client to build a virtual directory structure for use in executing a software title, streaming a subset of blocks associated with the software title to the client, and streaming additional blocks associated with the software title to the client on demand. A system for streaming software may include a server computer and a client computer. The server computer may include a program database and a streaming engine. In operation the streaming engine may stream an executable streaming application from the program database to the client.

Software streaming system and method

Method and system for executing a software application in a virtual environment includes a file system hook operatively interposed between a file system manager and a file system driver of the local computer, the file system hook configured to detect a file system call corresponding to a target program and to perform one or more procedures, and an agent procedure executing on the local computer to configure the file system hook for executing the target program. Also provided is a token file corresponding to the target program, the token file including file system overlay information for the target program. The one or more procedures may include accessing data at a server terminal operatively coupled to the local computer via a data network, or at a locally connected CD-ROM drive. Numerous other aspects are provided.

A technique for predictive streaming involves receiving a request for a block associated with a streaming application and serving data associated with the block. A block request database is checked to predict what block is likely to be requested next based upon prior block request data. The predicted block may be identified when serving the data associated with the requested block. A system developed according to the technique includes a streaming server, a block request database, and a prediction engine that uses the block request database to predict block requests. The streaming server provides data associated with the predicted block request.
