摘要： Disclosed is a system and method for implementing a distributed network system, such as the World Wide Web, in which distributed location services are utilized and include a collection of server processes that map from resource identifiers to a resource's controlling server. In addition, distributed location services provide an architecture for assigning resource identifiers and set of protocols for accessing server processes. The server processes are logically defined to provide a more flexible system. Each of these logical server processes are an abstraction which provides the external view of the server. The logical server processes may be implemented by different numbers of physical processes running on different machines at different points in time.

摘要： A XML-aware file system exploits attributes encoded in a XML document. The file system presents a dynamic directory structure to the user, and breaks the conventional tight linkage between sets of files and the physical directory structure, thus allowing different users to see files organized in a different fashion. The dynamic structure is based upon content, which is extracted using an inverted index according to attributes and values defined by the XML structure. In one application, a dynamically changing federated repository is searchable using a system of local and merged master indices, wherein query results are presented as virtual directory paths that are semantically organized.

摘要： Disclosed is a system and method for load balancing on a computer network that utilizes two levels of addressing abstraction—logical and physical. Logical processes are mapped to physical processes using a logical interface and may be done in a one-to-one, one-to-many, or many-to-one fashion. The mapping is dynamic in the sense that mapping decisions may include selection functions that can be changed on the fly so that servers can be added or removed in a manner that is relatively transparent to the client. The system and method are also applied to the World Wide Web so that web sites can also dynamically distribute processes over a plurality of servers.

摘要： Methods and apparatus for resolving access patterns in a data processing system using the pigeon hole principle are disclosed herein. The data processing system has a directed graph G of access patterns including a vertices set V representing cache items. Each cache item v has an access pattern defined by a path of vertices (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.n), v.sub.1 representing the start of the path and v.sub.n representing the end of the path at cache item v. The method includes defining a prefix cache for directed graph G which contains a map between an access pattern (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.k) and vertex v.sub.k for a kth level L in graph G, storing the prefix cache in a memory and, for a given access pattern (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.n), searching the prefix cache for a prefix (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.k) of the given access pattern that reaches the kth level L. If the search is successful, the method includes outputting vertex v.sub.k by reference to the stored prefix cache and calling an access pattern resolution primitive which accepts access pattern (v.sub.k+1 .fwdarw. , . . . , .fwdarw.v.sub.n) as an input and generates vertex v.sub.n as an output. If the search is unsuccessful, the method includes setting the input to the resolution primitive to the given access pattern (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.n) to generate vertex v.sub.n as the output. In either case, the given access pattern (v.sub.1 .fwdarw. , . . . , .fwdarw.v.sub.n) is fully resolved. Apparatus for performing this method is also disclosed. A particular use of the pigeon hole principle for caching in a data processing system involves the resolution of hierarchical file pathnames into in-core representations of the files named by the paths (i.e., namespace resolution) using prefix caching.
摘要翻译：本文公开了使用鸽孔原理解决数据处理系统中的访问模式的方法和装置。数据处理系统具有包括表示高速缓存项目的顶点集合V的访问模式的有向图G. 每个缓存项目v具有由顶点（v1->，...， - > vn）的路径定义的访问模式，v1表示路径的开始，vn表示高速缓存项目v处的路径的结束。包括定义用于有向图G的前缀高速缓冲存储器，其包含图G中的第k级L的访问模式（v1->，...， - vk）和顶点vk之间的映射，将前缀高速缓存存储在存储器中，对于给定的访问模式（v1->，...， - > vn），在前缀缓存中搜索达到第k级的给定访问模式的前缀（v1->，...， - > vk） L.如果搜索成功，则该方法包括通过参考所存储的前缀高速缓存输出顶点vk，并且调用接受访问模式（vk + 1→...，→vn）的访问模式解析原语作为输入并生成顶点vn作为输出。如果搜索不成功，则该方法包括将分辨率原语的输入设置为给定的访问模式（v1->，...， - > vn）以生成顶点vn作为输出。在任一情况下，给定的访问模式（v1->，...， - > vn）都被完全解析。还公开了用于执行该方法的装置。用于在数据处理系统中缓存的鸽孔原理的特定用途涉及使用前缀缓存将分层文件路径名解析为由路径命名的文件（即命名空间解析）的核心表示。
