    • 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.
    • 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。

    • A system and method that automatically and transparently handle client-side caching of network file data, independent of any remote file handling protocol. A protocol-independent client-side caching mechanism is inserted as a service that handles file-related requests directed to a network, and attempts to satisfy the requests via a client-side caching persistent store. By way of pre-process and post-process calls on a file create request, the caching mechanism creates file-related data structures, and overwrites the information in those structures that a buffering service uses to call back to a network redirector, whereby the client-side caching mechanism inserts itself into the communication flow between the network redirector and the buffering service. Once in the flow of communication, network-directed file read and write requests may be transparently handled by the client-side caching mechanism when appropriate, yet the redirector may be instructed to communicate with the server when needed to satisfy the request.
    • 独立于任何远程文件处理协议,自动和透明地处理网络文件数据的客户端缓存的系统和方法。 插入协议无关的客户端缓存机制作为处理与网络有关的文件相关请求的服务,并尝试通过客户端缓存持久存储来满足请求。 通过对文件创建请求的预处理和后处理调用,缓存机制创建与文件相关的数据结构,并覆盖缓冲服务用于回调到网络重定向器的那些结构中的信息,从而客户端 边缓存机制将自身插入到网络重定向器和缓冲服务之间的通信流中。 一旦进行通信,适当时,由客户端缓存机制可以透明地处理网络导向的文件读写请求,但是当需要满足请求时可指示重定向器与服务器进行通信。
