摘要： Published resources are made available in an encrypted form, using corresponding resource keys, published through resource key files, with the publications effectively restricted to authorized peer systems only by encrypting the resource keys in a manner only the authorized peer systems are able to recover them. In one embodiment, the resource keys are encrypted using encryption public keys of the authorized peer systems or the groups to which the authorized peer system are members. In one embodiment, the encryption public keys of individual or groups of authorized peer systems are published for resource publishing peer systems through client and group key files respectively. Group encryption private keys are made available to the group members through published group key files. Further, advanced features including but not limited to resource key file inheritance, password protected publication, obfuscated publication, content signing, secured access via gateways, and secured resource search are supported.

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.

摘要： Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.

摘要： A method and system for synchronizing objects among members of a replica set. Objects on members of the replica set are quickly synchronized via a join algorithm that takes advantage of version vectors. When an object is deleted, the object is tombstoned (i.e., marked as “dead”). Tombstones are also replicated between the connected members of the replica set. After a period of time (e.g., a timeout), the tombstones are deleted. A slow sync algorithm executes periodically to ensure that objects that were not deleted via replicated tombstones are eventually deleted. An époque algorithm provides that members that have been offline for a long period of time will update their objects before they participate in a join synchronization.

摘要： A communication protocol service in support of TCP based communication is modified to improve the operational efficiency of a server for a particular type of client-server application. The service is modified to support connection pools and connection groups within the connection pools, to enable connections with clients to be grouped and share a common file descriptor. The service is provided with an API to allow an application server to create the connection pools, connection groups and connections. The API also include receive and send services adapted to support the connection pool and connection group architecture, and to allow explicit acknowledgement of received transmissions under control of the application server. Further, in various embodiments, the buffering architecture of the service, as well as acknowledgement of request packets by the service are also modified.

摘要： The present invention finds candidate objects for remote differential compression. Objects are updated between two or more computing devices using remote differential compression (RDC) techniques such that required data transfers are minimized. An algorithm provides enhanced efficiencies for allowing the receiver to locate a set of objects that are similar to the object that needs to be transferred from the sender. Once this set of similar objects has been found, the receiver may reuse any chunks from these objects during the RDC algorithm.

摘要： The present invention is used to update objects over limited bandwidth networks. Objects are updated between two or more computing devices using remote differential compression (RDC) techniques such that required data transfers are minimized. In one aspect, efficient large object transfers are achieved by recursively applying the RDC algorithm to its own metadata; a single or multiple recursion step(s) may be used in this case to reduce the amount of metadata sent over the network by the RDC algorithm. Objects and/or signature and chunk length lists can be chunked by locating boundaries at dynamically determined locations. A mathematical function evaluates hash values associated within a horizon window relative to potential chunk boundary.

摘要： Binary executables are distributed in a distributed manner by equipping a server with a bootstrap program. The server provides the bootstrap program to a client computer in response to the client's request for the binary executables. The bootstrap program is designed to enable the client computer to obtain the binary executables in one or more portions from one or more peer locations that have already downloaded the said binary executables. In one embodiment, the bootstrap program also monitors the performance associated with obtaining the portions of the binary executables, and reports the performance data to a resource naming service that tracks peer locations that cache the binary executables. In one embodiment, the binary executables also includes a component that registers the client computer as a peer location that caches the binary executables, and provides the binary executables to other client computers responsive to their requests. In various embodiments, content is distributed in like manner.

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： 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.
