International Classification:

G06F015/16

US Classification:

709217000

Abstract:

An on-demand server configured to dynamically control and optimize memory utilization while minimizing access to disk storage by monitoring content addressable memory (CAM) usage so as to remove the content from resident CAM memory and page the same adaptively and to eliminate creating separate files for trick playback of content streamed to a customer. The method and system dynamically uses the current concurrency count of the contents to optimize memory utilization so as to swap content in and out of memory as the concurrency values change in conjunction with an on-demand memory based server to provided advantages of optimizing the usage of server resources.

Abstract:

Each set of pointers inserted into a received data stream eventually includes pointer values that point to other locations (e.g., other segments) within the data stream. Initially, pointer values can be set to null values because an address or respective index to other segments or other sets of pointers in the data stream may not be known until they are either received from the live feed or inserted into the data stream. As new segments of data are received from an original data stream such as a live feed, a processing function herein backfills the null pointer values in the set of pointers with appropriate values to the newly received segments or set of pointers. Backfilling of appropriate pointer values into the data stream enables a respective user viewing the data stream to initiate navigation amongst the data stream and potentially view a live feed with little or no delay.
