摘要： The invention relates to an apparatus for responding to data requests made by a client. The apparatus includes an input receiving a first data request that includes a sequence of nodes corresponding to a sequence of servers. The apparatus also includes decision logic determining whether the data specified in the data request is available on a selected server, and if the data is not available determining a next node from the sequence of nodes. The apparatus also includes a mapper mapping a server to the next node, and an output requesting the data by transmitting a second data request to the server mapped to the next node.

摘要： A network and a method for transmitting processes in a network are disclosed, where a randomized coding approach is provided. Network nodes transmit on each outgoing link a linear combination of incoming signals, specified by independently and randomly chosen code coefficients from a finite field. The approach allows robust, distributed transmission and compression of information in networks and is advantageous over routing-based approaches.

摘要： The invention relates to a method and apparatus for distributing a request to one of a plurality of resources. A request is mapped to a location in mathematical mapping space. Each of the plurality of resources is mapped to a respective location or locations in the mathematical mapping space. The request is allocated to one of the resources based on a mathematical relationship between the request location and the resource location in the mathematical mapping space. An apparatus for distributing a request to one of a plurality of resources includes the plurality of resources and an input receiving a resource request. A mapper in communication with the input maps the request to a request location in a mathematical mapping space and maps each of the plurality of resources to at least one resource locations in the mathematical mapping space. A distributor distributes the request to one of the plurality of resources in response to a mathematical relationship between the locations of the request and resources in the mathematical mapping space.

摘要： Scatter-Gather is a computer based document browsing method which operates in time proportional to a number of documents in a target corpus. The Scatter-Gather method includes: preparing an initial ordering of the corpus using, for example, an off-line computational method; determining a summary of the initial ordering of the corpus for interactive utility; and providing a further ordering of the corpus using, for example, an on-line non-deterministic method. The step of an off-line preparation of an initial ordering of a corpus is non-time-dependent, thus an accurate initial ordering is prepared. The step of determining a summary includes determining a summary for presentation to a user without scrolling on a CRT. The step of providing a further ordering includes truncated group average agglomerate clustering, merging disjointed document sets, center finding, assign-to-nearest and other refinement methods.
摘要翻译： Scatter-Gather是一种基于计算机的文档浏览方法，与目标语料库中的文档数量成正比。分散收集方法包括：使用例如离线计算方法来准备语料库的初始排序; 确定用于交互式实用程序的语料库的初始排序的摘要; 并使用例如在线非确定性方法提供语料库的进一步排序。离线准备语料库的初始排序的步骤是非时间依赖的，因此准备了准确的初始排序。确定摘要的步骤包括确定用于呈现给用户的摘要，而不在CRT上滚动。提供进一步排序的步骤包括截断组平均聚集聚类，合并不相关文档集，中心查找，分配到最近和其他细化方法。
