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.

Claims

1. A system comprising:

a virtual execution environment;

a block granularity caching engine;

a cache;

wherein, in operation;

a process associated with a stream-enabled application is executed in the virtual execution environment;

the virtual execution environment intercepts a request from the process executing in the virtual execution environment;

the virtual execution environment identifies one or more blocks that are associated with the resource;

the virtual execution environment makes a block request associated with the resource;

the block granularity engine checks the cache for blocks to satisfy the block request;

the client block granularity engine provides at least one predictively streamed block to the virtual execution environment if the predictively streamed block is found in the cache;

the virtual execution environment satisfies the resource request of the process using the at least one predictively streamed block.
