Immutable sharable zero-copy data and streaming

摘要

The environment and use of an immutable buffer. A computing entity acquires data or generates data and populates the data into the buffer, after which the buffer is classified as immutable. The classification protects the data populated within the immutable buffer from changing during the lifetime of the immutable buffer, and also protects the immutable buffer from having its physical address changed during the lifetime of the immutable buffer. As different computing entities consume data from the immutable buffer, they do so through views provided by a view providing entity. The immutable buffer architecture may also be used for streaming data in which each component of the streaming data uses an immutable buffer. Accordingly, different computing entities may view the immutable data differently without having to actually copy the data.

1. A method for sharing data between multiple computing entities, the method performed by executing computer-executable instructions upon one or more computer processors, the method comprising:
executing computer-executable instructions upon one or more computer processors for performing:
an act of populating a buffer with data;an act of classifying the buffer as an immutable buffer, wherein the classification protects the data populated within the immutable buffer from changing during the lifetime of the immutable buffer, and also protects the immutable buffer from having its physical address changed during the lifetime of the immutable buffer;an act of granting a first view of the immutable buffer to a first computing entity; andan act of granting a second view of the immutable buffer to a second computing entity, wherein the second view is different than the first view.
