A conventional operating system folder or directory based file system is implemented with, or enhanced to provide, attributes of shared collaborative workspaces. In particular, the conventional file system is connected to either a server based or a distributed collaboration system and the user interface of the operating system file system is augmented to allow it to control aspects of the collaboration system. Each folder or directory can be synchronized and treated as a “workspace” that can be viewed and shared with other users or groups of users. Folder can also be provided with “awareness” information that indicates collaborators that are present and those that are sharing the workspace.

A method for backing up data in a plurality of computers connected via a network. The method includes forming partnerships between the plurality of computers such that each computer in a partnership commits under agreements to help backup the data of its partners. The method further includes periodically verifying that previously backed up data is being retained by the computers committed to act as backup partners in accordance with the agreements. In another embodiment, the method provides a distributed cooperative backing up of data in a system that includes a loose confederation of computers connected via a network. In this embodiment the method includes selecting computers as potential backup partners from among the loose confederation of computers connected via the network based on predetermined criteria, and negotiating a reciprocal backup partnership agreement between the computers based on predetermined requirements, including backup requirements. Once the negotiations are complete and the agreements are made, the method proceeds to form partnerships between the computers. The computers become backup partners by agreeing to cooperatively provide backup services to each other so that a distributed cooperative backing up of data can be administered in the absence of central control. The method further includes periodically backing up data at the backup partners, where the data being backed up is encoded. The method also includes periodically verifying that previously backed up data is retained by the backup partners. Another aspect of the invention is a distributed cooperative backup system that includes a network and a loose confederation of computers connected via the network. A plurality of computers from among the loose confederation of computers is configured for distributed cooperative backing up of data and for functioning as backup partners. Each computer of the plurality of computers has a storage that can be used for providing reciprocal backup services. Each computer of the plurality of computers respectively also has a computer readable medium embodying computer program code configured to cause the computer to perform functions comparable to the method steps as described above.

A method of provisioning in a cloud compute environment having a set of cloud hosts associated with one another. The method begins by forming a distributed, cooperative cache across the set of cloud hosts by declaring a portion of a data store associated with a cloud host as a cache, and storing template images and patches in the cache. Caching activity across the distributed, cooperated cache is coordinated by having the caches share information about their respective contents. A control routine at a cache receives requests for template images or patches, responds to the requests if the requested artifacts are available or, upon a cache miss, forwards the request to another one of the caches. Periodically, the composition of the distributed, cooperative cache is computed, and the template images and patches are populated into the caches using the computed cache composition.

Multiple cooperative relays operate in a highly mobile environment and form a virtual antenna array. Multiple independent streams of data can be simultaneously transmitted in parallel to the destination receiver. Thus a higher spatial multiplexing gain can be obtained. Such exemplary embodiments might do so by allowing each relay to transmit a linear combination of antenna waveforms according to an independently and randomly generated coefficient vector. This randomized cooperation scheme may be useful in an environment in which a group of relay devices are close to the source device, and can therefore receive information at a high rate. Each relay device that receives the information without errors splits it into multiple streams. For example, if the relay devices receive B symbols and the number of streams is K, each stream contains B / K symbols. Each relay device then generates a random linear combination of all the streams and transmits this output simultaneously with the other relay devices.

A system, method, and article of manufacture that allow a document containing custom objects to be shared in a distributed collaborative computer system. This is accomplished by allowing custom objects to be embedded in a document. When the document is to be shared, the document with custom objects is converted to a Rich Multi-Media (RMM) format. Furthermore, the converted document may be shared during a collaborative session among multiple computers. Alternatively, the converted document may be viewed by a user independent of a collaborative session.

This invention treats of a two-level cache management method for continuous media files of a proxy server. In the first level, the method reserves collapsed buffers in the cache for every active client attended by the proxy server. To save bandwidth and memory space collapsed buffers can be concatenated and overlapped when content belongs to the same continuous media file. The proxy manages collectively the collapsed buffers of each client, which cooperate by making its content available to the whole system, reducing traffic over the communication network and on the media-on-demand server. In the second level, the method allows proxy servers to cooperate between themselves, by concatenating collapsed buffers when necessary, increasing the amount of available shared media in the cache, saving bandwidth both on the media-on-demand server and on the communication network backbone.
