Verizon Digital Media Services Assigned Patent

Verizon Digital Media Services Inc., Dulles, VA, has been assigned a patent (10,904,307) developed by Sathyanarayana, Karthik, Cypress, CA, Bedi, Harkeerat Singh, Shiell, Derek, Los Angeles, CA, and Peters, Robert J., Culver City, CA, for a “distributed management of live stream storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The solution distributes the management of stream segments from a central storage cluster to different edge servers that upload stream segments to and receive stream segments from the central storage cluster. Each edge server tracks the stream segments it has uploaded to the central storage cluster as well as the expiration times for those segments. The tracking is performed without a database using a log file and file system arrangement. First-tier directories are created in the file system for different expiration intervals. Entries under the first-tier directories track individual segments that expire within the expiration interval of the first-tier directory with the file system entries being files or a combination of subdirectories and files. Upon identifying expired stream segments, the edge servers instruct the central storage cluster to delete those stream segments. This removes the management overhead from the central storage cluster and implements the distributed management without a database.”

The patent application was filed on December 6, 2017 (15/832,921).
