Patent number: 10802914Abstract: A disclosed method is performed at a fault-tolerant object-based storage system including M data storage entities, each is configured to store data on an object-basis. The method includes obtaining a request to store N copies of a data object and in response, storing the N copies of the data object across the M data storage entities, where the N copies are distributed across the M data storage entities. The method additionally includes generating a first parity object for a first subset of M copies of the N copies of the data object, where the first parity object is stored on a first parity storage entity separate from the M data storage entities. The method also includes generating a manifest linking the first parity object with one or more other subsets of M copies of the N copies of the data object.Type: GrantFiled: July 23, 2018Date of Patent: October 13, 2020Assignee: Cisco Technology, Inc.Inventors: Clint Ricker, Ryan Michael Okelberry, Dana Marlow Henriksen, Mel J. Oyler, Hoi-Tauw Jozef Chou, Kevin Wayne Kingdon

Patent number: 10782888Abstract: Various implementations of hard disk track management method, device, and system disclosed herein enable improvements of file system write bandwidth. In various implementations, a method is performed at a disk storage including a file controller controlling a disk drive with a disk platter that is divided into multiple regions including a fast region. In various implementations, the method includes receiving a write request associated with data to be written to the disk drive and in response, determining a disk utilization of the disk drive. In various implementations, the method further includes placing the disk drive in a surge mode to write the data to the fast region upon determining that the disk utilization is above a first threshold, and placing the disk drive in a non-surge mode to write the data to other regions of the multiple regions upon determining that the disk utilization is below a second threshold.Type: GrantFiled: June 25, 2018Date of Patent: September 22, 2020Assignee: Cisco Technology, Inc.Inventors: Ryan Michael Okelberry, Dana Henriksen, Mel J.

Patent number: 8850474Abstract: A virtual content store may be provided. Upon receiving a request for a content stream from a subscriber at a regional headend, a central content vault may be examined to determine whether the content stream is available. Once the content stream is determined to be available in the central content vault, a streaming session may be established to the subscriber from the regional headend. The content stream may be retrieved from the central content vault and provided to the subscriber via the streaming session.Type: GrantFiled: July 26, 2010Date of Patent: September 30, 2014Assignee: Cisco Technology, Inc.Inventors: Khalid Mohammed Azam, Neeraj Kumar Sharma, Gary Ward Richardson, Daniel Michael Kiewlich, Hoi-Tauw Jozef Chou

Patent number: 8166179Abstract: A method and system for managing media streaming between clients on a client side of a network and stream servers on a stream server side of the network, wherein communications between the client side and the stream server side require a network address translation (NAT), involves allowing the same stream server side IP address to be shared amongst multiple stream servers so that the stream servers can simultaneously use the same IP address to source different media sessions. Because the stream servers can simultaneously use the same IP address to source different media sessions, a media session can be switched from one stream server to a different stream server without triggering STUN signaling or a change in the NAT mapping.Type: GrantFiled: January 30, 2009Date of Patent: April 24, 2012Assignee: Cisco Technology, Inc.Inventors: John Pickens, Hoi-Tauw Jozef Chou, Joshua B.
