| 20100005072 | Nomadic File Systems - Objects contained within enormous geographically distributed virtual file servers are each assigned globally unique object identifiers. For any given global scope object identifier, the file system containing the identified object can be quickly located even when the file system is frequently unmounted from one DDS file server and mounted on another (possibly geographically remote) file server such that it is essentially a nomadic (or wandering) file system. | 01-07-2010 |
| 20100036840 | Presentation of Search Results - Objects contained within enormous geographically distributed virtual file servers spanning thousands (or even millions) of organizations are each assigned globally unique object identifiers, enabling the implementation of highly distributed indexing and retrieval operations. The file system API (application programming interface) is extended to provide a search capability. A search request targeting a specific domain creates a parallel namespace anchored in that domain's root directory. The parallel namespace, containing directories and links to all objects satisfying the search criteria, may be navigated using the standard file system API. Relevance scores, added as new members of the file attribute structure, enable the construction and presentation of views that convey where the centers of expertise associated with the search matter are located. In addition, a wide range of methods addressing the scalability issues associated with integrating retrieval operations into the fabric of geographically distributed virtual file servers are disclosed. | 02-11-2010 |
| 20100070982 | Distributed File System Consistency Mechanism Extension For Accelerating Communications Between Distributed Applications - Systems and methods for extending the functionality of the consistency callback mechanisms employed by local file systems such as NTFS and distributed file systems such as DDS, NFS and CIFS so as to provide a shared memory foundation for the support of highly interactive distributed applications are disclosed. Distributed applications establish connections to a common distributed file system object; each application registers the file system events for which it wants to receive a notification (either synchronously or asynchronously). In this manner, each application becomes almost instantly aware of the file access activities for which it registers and which are being performed by the other applications. | 03-18-2010 |
| 20100082774 | Distributed File System Consistency Mechanism Extension for Enabling Internet Video Broadcasting - The consistency callback mechanisms employed by local file systems such as NTFS and distributed file systems such as DDS, NFS and CIFS are extended to provide a shared memory foundation for efficiently broadcasting real-time high definition video from a source object to large numbers of viewers via the Internet. Distributed applications such as video viewing client applications establish connections to a common distributed file system object, and then each application registers with the underlying distributed file system to receive notifications whenever the video source modifies the source object. The data required to update images maintained by viewing clients is included in notification messages. The distributed file system employs a network of proxy cache nodes. Proxy cache nodes receive notification messages (complete with image update data) and update their cached images of the source object and then retransmit the notification messages towards the viewing clients using IP multicast techniques. In this manner, the distributed file system's consistency mechanism efficiently employs network resources to enable the real-time distribution of video content streams. | 04-01-2010 |
| 20130325916 | Full text search capabilities integrated into distributed file systems - Incrementally Indexing Files - A hierarchical distributed search mechanism is integrated into a distributed file system. Traditional file system APIs (create, open, close, read, write, link, rename, delete, . . . ) and the over-the-wire protocols employed to project these APIs into remote client sites (CIFS, NFS, DDS, Appletalk) are extended to enable the dynamic creation of temporary directories containing links to objects identified by search engines (executing at sites “close” to “their” data) as meeting the search criteria specified by the first parameter of a search function call. The search function, derived from the standard file system API function create, is added to the file system API. | 12-05-2013 |
