摘要： Various embodiments can utilize a distributed solution for scheduling connections between peers in a file sharing environment. In accordance with at least some embodiments, individual nodes in a peer-to-peer system include scheduling software that enables the nodes to make scheduling decisions with regard to how, when and where connections are made with other peers. Scheduling decisions can be based on a number of different parameters. In at least some embodiments, a synchronization negotiation manager is embodied with logic that drives the negotiation and scheduling process. This logic is represented by an innovative state machine that is designed to implement the negotiation and synchronization process.

摘要： A system for stimulating the production of hydrocarbon containing substances, such as from oil and gas wells, by the use of a generally cylindrical, high energy producing transducer mechanism. The transducer comprises a series of aligned transducer elements, preferably formed of doped ceramic piezoelectric materials, encased in a housing maintained under controlled pressure by a pressure compensator to equalize the pressure within the housing to that of the surrounding strata containing the hydrocarbon substance. When energized, the respective transducer elements transmit a very narrow, horizontal beam of ultrasonic energy radiating omni directionally, preferably in a narrow band of about 2 to 3°, to thereby focus the energy horizontally for maximum penetration into the surrounding strata.

摘要： Implementations of the present invention relate to a communication framework that is readily adaptable to a wide variety of resources intended to be accessible through a firewall. In general, a communication framework at a gateway server can provide a specific connection to a requested resource in accordance with a wide range of resource and/or network access policies. In one instance, a client requests a connection to a specific resource behind a firewall. The communication framework authenticates the connection, and quarantines the connection until determining, for example, that the client is using an appropriate resource features. If appropriately authenticated, the communication framework can pass control of the connection to an appropriately identified protocol plug-in processor, which facilitates a direct connection to the requested resource at an application layer of a communication stack.
摘要翻译：本发明的实现涉及一种易于适应旨在通过防火墙访问的各种资源的通信框架。通常，网关服务器处的通信框架可以根据广泛的资源和/或网络访问策略提供与请求的资源的特定连接。在一种情况下，客户端请求与防火墙后面的特定资源的连接。通信框架认证连接，并隔离连接，直到确定客户端正在使用适当的资源特征。如果适当地认证，则通信框架可以将连接的控制传递到适当识别的协议插件处理器，这有助于在通信栈的应用层处直接连接到所请求的资源。

摘要： Implementing a consistent user name-space on networked computing devices includes various components and methods. When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable. When the network connection is lost or items located on a remote computer are otherwise unavailable, the unavailable items remain represented on the host computing device. Unavailable items are represented in a way that informs the user that the items may not be fully accessed.

摘要： Various embodiments introduce the notion of a replication entity which implements a highly scalable file replication system. In one embodiment, the replication entity resides in the form of a scalable replication service. In at least some embodiments, the replication service provides a “drive in the sky” facility that can be used by individuals, such as subscribers, to synchronize their individual machines, such that their files are automatically replicated to a safe and always-on location. Alternatively or additionally, individuals such as subscribers can also access their files via a web-based interface when they are away from their machines.

摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

摘要翻译：本发明提供了一种新颖的客户端缓存（CSC）基础设施，其支持目录级别的转换状态，以促进跨客户端和远程服务器之间的连接状态的无缝操作。更具体地，执行持续高速缓存以跨连接中断和/或带宽改变来保护用户（例如，客户端）和/或客户端应用。这部分是通过将客户端数据存储器连同适当的文件访问参数一起缓存所需的文件来实现的。此外，客户端在断开连接期间保持对缓存文件的访问。此外，路径的一部分可以离线，而上游的其他部分可以保持联机。 CSC在与物理路径上运行的DFS协作的逻辑路径上运行，以跟踪缓存，访问和更改目录中的文件。此外，无论文件副本是否存在冲突，客户端上的真相都是有利的。

摘要： Clients may subscribe to resources for the purpose of receiving notifications of changes in the resource (e.g., a file is added to a shared folder). Storing subscriptions within persistent storage provides data security in the event of a service failure, at the cost of high latency in accessing subscription data. An efficient method for tracking a resource is provided herein. A subscription service creates subscriptions and monitors resources for a client. Upon a subscribed resource change, a notification service stores a notification of the change into a queue associated with the client. Efficient resource tracking is achieved because notification and subscription data is stored in low latency soft memory. The notification service is configured to detect a failure in the notification service and/or subscription service. In the event a service fails, the client provides a recovery mechanism by resubscribing to resources the client is interested in.
摘要翻译：客户可以订阅资源，以便接收资源更改的通知（例如，将文件添加到共享文件夹）。在永久存储器中存储订阅会在服务发生故障的情况下提供数据安全性，代价是访问订阅数据的高延迟。本文提供了一种跟踪资源的有效方法。订阅服务创建订阅并监视客户端的资源。在订阅的资源更改时，通知服务将更改的通知存储到与客户端相关联的队列中。由于通知和订阅数据存储在低延迟软存储器中，因此实现高效的资源跟踪。通知服务被配置为检测通知服务和/或订阅服务中的故障。在服务失败的情况下，客户端通过重新订阅客户端感兴趣的资源来提供恢复机制。

摘要： The present invention is directed at a system and method for managing and evicting objects stored in a cache. The invention provides a mechanism for determining which objects to evict based on a weight that is calculated for each object stored in the cache. The weight is determined by at least two factors, including file size, file type, primary user, last access time, and the like, and by the relative importance of each of the factors. The weight for each object may be determined autonomously and/or may be determined upon a trigger event. The factors and their relative importance may be obtained from a policy applicable to one or several computers.
