Embodiment Construction

[0057] As discussed above, existing solutions do not take into account how to prolong the possibility of fragmented reuse of popular VoD content. Furthermore, existing solutions do not take advantage of the relationship between the current segment of content and other segments of content, especially segments following the current segment. Specifically, if one segment of a piece of content is very popular, subsequent segments are likely to be popular as well. In this regard, there is a need to provide a well-defined forecasting mechanism applicable to VoD applications.

[0058] However, for those skilled in the art, how to perform dynamic optimization of popular VoD content reuse in order to reduce I / O reads of streaming servers is always a challenging problem. The following embodiments provide solutions to the technical problems described above.

[0059] The embodiments set forth below represent the necessary information to enable one skilled in the art to practice the inven...

Abstract

The present invention provides a method of and a system for providing buffer management mechanism in an on-Demand environment to keep the popular content sections in server memory so as to reduce the repeatable disk I / O and improve the server performance. The method comprises: setting the state of a buffer to be ACTIVE when a file section stored in the buffer is requested by any users; setting the state of the buffer to be INACTIVE when users no longer request the file section stored in the buffer, the buffer in INACTIVE state having a lifetime; changing the state of the buffer from INACTIVE to FREE when the lifetime decreases to zero. The system comprises at least one detector for detecting the number of the users requesting a file section stored in the buffer and providing the detection results for a processor, one processor for determining the state of the buffer according to the detection results and providing instructions for at least one state setting unit, and at least one state setting unit for setting the state of the buffer based on instructions from the processor.

Description

technical field [0001] The invention relates to the technical field of streaming media. In particular, the present invention relates to methods and systems for providing a buffer management mechanism in an on-demand environment. Background technique [0002] With the advent of digital media technology, it is feasible to provide on-demand services, such as video-on-demand (VoD) services, to a large number of customers through geographically distributed networks. In order to guarantee continuous delivery of video streams to clients, streaming servers are used for storage resources. [0003] A video streaming server is a device capable of streaming hundreds or thousands of video streams to set-top boxes or mobile terminals at customer locations. The content itself can reside on CDs, conventional spinning disks, flash disks, or even RAM. The most used storage device today is the conventional disk due to its low price per data volume. In video-on-demand applications, popular ...
