    摘要: Peer devices register with a resource locator service so that the peer devices can be uniquely identified in a networking environment. An addressing scheme addresses a peer resource in the networking environment based on the unique identifier of a peer device that is a master publisher of the resource. Based on the addressing scheme, the resource locator service can track the location of the master publisher of the resource as well as additional locations of peer devices that have cached the resource and made it available. In various embodiments, the resource locator service can service requests for peer resources by providing a list of locations where the resource is expected to be available or, in the case of non-compatible requester, provide access to the resource itself.

    摘要: A resource naming service (RNS) server receives peer resource requests from peer platforms through a networking environment. The RNS server, possibly in cooperation with other RNS servers and peer registrars generates a response to the request to enable the peer platforms to access the requested peer resources. In one embodiment, a response includes a list of locations of peer devices in the networking environment where a resource is expected to be available. A requesting device can then choose to access the resource from one or more of the listed peer locations.

    摘要: The present invention provides a method for chunking an object. The method is arranged to provide efficient chunking of objects such that objects can be efficiently updated between a remote machine and a local machine over a network. The chunking algorithm is applicable in networked application such as file synchronization using remote differential compression (RDC) techniques. The chunking algorithm provides enhanced efficiencies by locating chunk boundaries around local maxima.

    摘要: A method and system for controlling which content gets precedence and is replicated. A replica set is comprised of a set of resources. Each resource is associated with resource data and resource meta-data. For files-based systems, resource data includes file contents and attributes, while resource meta-data includes additional attributes that are relevant for negotiating synchronization during replication. An extra field called a “fence value” is added to the meta-data associated with each resource. During synchronization, first fence values are compared. The resource with the highest fence value includes the content that is controlling and replicated. If fence values are equal (and greater than a particular value), the controlling resource is determined based on other meta-data.

    摘要: Aspects of the subject matter described herein relate to shutdown recovery for resource replication systems. In aspects, a mechanism is described in which a machine having replicated data thereon can recover from a dirty shutdown. First, the machine determines whether a dirty shutdown has occurred. If so, the machine automatically performs shutdown recovery by causing resource metadata stored by the machine to be consistent with resource data stored by the machine. This may involve fixing the resource metadata for updates to the resource data that were not flushed to disk or may involve deleting the resource metadata and restoring it from another machine replicating the data.

    摘要: A computing device has a file stored on a storage volume by a file system and accessed through such file system. The file is defined to include data and metadata relating to the data, and at least a portion of the data of the file is removed from the file and stored at an alternate location such that the data does not occupy substantially any space on the volume and the file is in a reduced, ghosted form. The ghosted file is reconstituted for use by retrieving the data from the alternate location and associating such retrieved data with such ghosted file to form the reconstituted file.
