20080201335 | Method and Apparatus for Storing Data in a Peer to Peer Network - A fixed prefix peer to peer network has a number of physical nodes. The nodes are logically divided into a number of storage slots. Blocks of data are erasure coded into original and redundant data fragments and the resultant fragments of data are stored in slots on separate physical nodes such that no physical node has more than one original and/or redundant fragment. The storage locations of all of the fragments are organized into a logical virtual node (e.g., a supernode). Thus, the supernode and the original block of data can be recovered even if some of the physical nodes are lost. | 08-21-2008 |

20090265360 | Dynamically Quantifying and Improving the Reliability of Distributed Data Storage Systems - Data is stored in a distributed data storage system comprising a plurality of disks. When a disk fails, system reliability is restored by executing a set of reconstructions according to a schedule. System reliability is characterized by a dynamic Normalcy Deviation Score. The schedule for executing the set of reconstructions is determined by a minimum intersection policy. A set of reconstructions is received and divided into a set of queues rank-ordered by redundancy level ranging from a lowest redundancy level to a highest redundancy level. For reconstructions in each queue, an intersection matrix is calculated. Diskscores for each disk are calculated. The schedule for the set of reconstructions is based at least in part on the intersection matrices, the Normal Deviation Scores, and the diskscores. | 10-22-2009 |

The resource identifier parser can understand the formatting of resource identifiers of specific domains and can derive therefrom information such as coordinates of a map page, the title of classified listings, and other like information. If the resource identifier cannot be parsed, the identified data page can be referenced to identify services offered by the page, such as data feed services, which can then be presented to the non-browser application program or the operating system to which the resource identifier was provided. As yet another alternative, the domain can provide a customized resource identifier parser to parse its resource identifiers. Such a customized parser can be either downloadable and locally executable or it can be a network service. | 12-29-2011 |
