Abstract

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.

First claim

1 . A method comprising:
receiving a request, from a streaming playback device, for a block of a stream-enabled application; determining likelihood of each of additional blocks of the stream-enabled application being requested based on an identification of the block of the stream-enabled application using probability data; adding the block of the stream-enabled application requested by the request and then at least a portion of the additional blocks of the stream-enabled application to an output buffer in order of decreasing likelihoods of the additional blocks of the stream-enabled application being requested within a data window size of the output buffer, the data window size of the output buffer being varied based on at least one of a latency and a throughput that are dynamically changing; providing the block of the stream-enabled application requested by the request and the at least the portion of the additional blocks in the output buffer to the streaming playback device.
