摘要： A system and method for implementing a consistent user name-space on networked computing devices is provided. 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： 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： 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.

摘要： A source device and a target device may endeavor to form a secure communication session whereby encrypted messages may be transmitted over an untrusted network, such as the internet. However, the exchange of many messages in the establishment of the communication session may involve considerable latency and computational resources, particularly in scenarios featuring many communication sessions (e.g., peer-to-peer communication sessions.) Techniques for initiating a communication session may be devised that enables the initiation of a communication session with only two exchanged messages, or even with a single message transmitted from the source device to the target device. Some embodiments of these techniques may also permit the inclusion of advantageous security features, such as authentication via public certificate to detect man-in-the-middle attacks and the inclusion of nonces to detect replay attacks, without increasing the number of messages involved in the initiation of the communication session.

摘要： One or more techniques and/or systems are provided for processing data requests received over various communication protocols. In particular, a data transfer component may be configured to process data requests and/or responses between requesting devices and data handlers utilizing various communication protocols (e.g., peer-to-peer communication protocols, web based communication protocols, etc.). In particular, communication protocol functionality may be abstracted away from the data handlers, and may be handled by the data transfer component. In this way, data handlers may be communication protocol agnostic because the data transfer component may perform the communication protocol functionality on behalf of the data handlers, which may allow the data handlers to be more “lightweight” and focus primarily on fetching and/or formatting requested data.

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.
