摘要： A method and system for transparently combining remote and local storage to provide an extended file system such as a virtual local drive for a computer system client/user, e.g., a user of a pocket sized personal computer or a cable set-top box. A client device may load file system object data, storing the directories and files remotely, and retrieving the files only when required. Via its local storage, the extended file system handles unreliable connections and delays. When a connection to an extended file system server is present, the extended file system provides automatic downloading of information that is not locally cached, and automatically uploading of information that has been modified on the client. Extended file system attributes are employed to determine the actual location of file system data, and a lightweight protocol is defined to download or upload remote data by low-level components that make the remote source transparent from the perspective of the application. The system scales to large networks as it employs the lightweight protocol and establishes a connection only to retrieve and submit data.
摘要翻译：一种用于透明地组合远程和本地存储器以提供扩展文件系统的方法和系统，例如用于计算机系统客户端/用户的虚拟本地驱动器，例如袖珍型个人计算机或有线机顶盒的用户。客户端设备可以加载文件系统对象数据，远程存储目录和文件，只有在需要时才能检索文件。通过其本地存储，扩展文件系统处理不可靠的连接和延迟。当与扩展文件系统服务器的连接存在时，扩展文件系统提供自动下载不是本地缓存的信息，并自动上传已在客户端上修改的信息。使用扩展文件系统属性来确定文件系统数据的实际位置，并且定义了一个轻量级协议，以便从应用程序的角度使远程源透明的低级组件下载或上传远程数据。该系统使用轻量级协议扩展到大型网络，并建立一个仅用于检索和提交数据的连接。
