摘要： Data is automatically shared over one or more contact networks which are interrelated by a trust relationship. The data can be shared using a network-based communication service and is stored as a data record in a local data store. The communication service may be implemented as an instant messaging, electronic mail, mobile phone or some other type of communication service. The data record can include data created by a user, a relevance value, a maximum share count and/or other data. The number of times that data may be shared may be configured by the user that generates the data. The relevance of the data may be updated each time the data is shared.
摘要翻译：数据通过一个或多个由信任关系相互关联的联系网络自动共享。可以使用基于网络的通信服务共享数据，并将其作为数据记录存储在本地数据存储中。通信服务可以被实现为即时消息，电子邮件，移动电话或某种其他类型的通信服务。数据记录可以包括由用户创建的数据，相关值，最大共享数和/或其他数据。可以共享数据的次数可以由生成数据的用户进行配置。每次数据共享时，可能会更新数据的相关性。

摘要： The addition of a layer between a tree data storage structure and a persistent storage is disclosed. The additional layer, called a storage module, generates an identifier and allocates it to a node in the tree data storage structure. The storage module additionally performs a mapping function, allocating the identifier to a location in persistent storage. If the node is later deleted from the tree data storage structure, then the mapping of the identifier to the location in persistent storage is likewise deleted. In this way, if the node is deleted and, concurrently, a lookup or write operation is attempted on the deleted node, the storage module will read the identifier associated with the deleted node but will not be able to map the identifier to a location in persistent storage. Instead, an exception is generated and sent to the tree data storage module.

摘要： An invention is disclosed whereby a wireless network node, equipped with two or more radio transceivers statically tuned to non-interfering frequency channels, can make decisions regarding which channel to use when communicating with a neighboring wireless node. A multi-radio unification protocol implemented in a wireless node coordinates the use of multiple wireless network interface cards and provides a virtual layer that hides the multiple physical network interfaces from higher layers of a node's network protocol stack. The invention is applicable to wireless networks generally, including those in which some nodes do not have multiple radios or do not recognize the multi-radio unification protocol. The invention makes possible simultaneous transmissions using available channels, thereby reducing interference and delay while increasing the overall capacity of the network.

摘要： Multiple versions of data on different sets of machines allow a system to degrade gracefully even when experiencing excessive failures. When excessive failures cause the latest versions to be unavailable, the system becomes degraded, but still offers an old version if available. A most recent coherent set of the available older versions is found and provided. The degree of degradation increases gradually as the system experiences more and more failures. Graceful degradation is desirably complementary to fault tolerance.
摘要翻译：不同机器组上的多个版本的数据允许系统即使在遇到过多故障时也能正常降级。当过多的故障导致最新版本不可用时，系统会降级，但仍然提供旧版本（如果可用）。最新的一系列可用的旧版本被发现和提供。系统经历越来越多的失败，退化程度逐渐升高。优雅的降解是容错的补充。

摘要： A distributed system checker may check a distributed system against events to detect bugs in the distributed system. The events may include machines crashes, network partitions, and packet losses, for example. The distributed system checker may check a distributed system that can have multiple threads and multiple processes running on multiple nodes. To obtain control over a distributed system, a distributed system checker may insert an interposition layer between a process and the operating system on each node.

摘要翻译：公开了在树数据存储结构和持久存储器之间添加层。称为存储模块的附加层生成一个标识符，并将其分配给树形数据存储结构中的一个节点。存储模块还执行映射功能，将标识符分配给持久存储器中的位置。如果稍后从树数据存储结构中删除节点，则同样删除标识符到持久存储器中的位置的映射。以这种方式，如果节点被删除，并且并发地在被删除的节点上尝试查找或写入操作，则存储模块将读取与被删除的节点相关联的标识符，但是将不能将标识符映射到持久存储。相反，会生成异常并将其发送到树数据存储模块。

摘要： A network troubleshooting framework is described. In an implementation, a method includes forming a plurality of reports by a plurality of nodes in a network, wherein each of the reports is formed by a respective one of the nodes and includes trace data obtained from the respective node and another of the nodes. An inconsistency is detected in the trace data in one of the reports when compared with corresponding trace data in another of the reports. A set of the nodes is found that formed one or more of the reports having the inconsistency in the trace data.

摘要： A distributed data store employs replica placement techniques in which a number k hash functions are used to compute k potential locations for a data item. A number r of the k locations are chosen for storing replicas. These replica placement techniques provide a system designer with the freedom to choose r from k, are structured in that they are determined by a straightforward functional form, and are diffuse such that the replicas of the items on one server are scattered over many other servers. The resulting storage system exhibits excellent storage balance and request load balance in the presence of incremental system expansions, server failures, and load changes. Data items may be created, read, and updated or otherwise modified.
