摘要： Methods and systems for indexing subband selections are disclosed. The selected subbands can be represented as a binary sequence and the index can be determined by employing a choose function, where a choose function value for a particular selected bit position is defined by a selection occurrence count of the selected bit position that is chosen from a bit position count of the selected bit position. In particular, the index can be the summation of choose function values for each selected bit position.

摘要： In a communication arrangement, client terminals request information objects, e.g., hypertext markup language (HTML) documents, which are identified by their uniform resource locators (URLs) from a server system connected to the World Wide Web (WWW). For example, the information objects may represent different chapters of the same book and are thus logically connected. In accordance with the invention, when the logically connected information objects are updated, the updated versions of the information objects are stored in a temporary memory space. For those client terminals requesting the logically connected information objects by their URLs before the update, the server system consistently provides the original versions of the information objects at such URLs to the client terminals. However, for those client terminals requesting the logically connected information objects by their URLs after the update, the server system translates the given URLs to different URLs indicating the memory locations where the updated versions thereof are stored, thereby consistently providing the updated versions to the client terminals.
摘要翻译：在通信方案中，客户端终端从连接到万维网（WWW）的服务器系统请求由其统一资源定位符（URL）标识的信息对象，例如超文本标记语言（HTML）文档。例如，信息对象可以表示同一本书的不同章节，因此逻辑上是连接的。根据本发明，当逻辑连接的信息对象被更新时，信息对象的更新版本被存储在临时存储器空间中。对于那些在更新之前通过其URL请求逻辑连接的信息对象的客户终端，服务器系统始终将这些URL处的信息对象的原始版本提供给客户终端。然而，对于那些在更新之后通过其URL请求逻辑连接的信息对象的客户终端，服务器系统将给定的URL转换成指示存储其更新版本的存储器位置的不同URL，从而始终向客户端提供更新的版本终端。

摘要： A server system for processing client requests received over a communication network includes a cluster of N document servers and at least one redirection server. The redirection server receives a client request from the network and redirects it to one of the document servers, based on a set of pre-computed redirection probabilities. Each of the document servers may be an HTTP server that manages a set of documents locally and can service client requests only for the locally-available documents. A set of documents are distributed across the document servers in accordance with a load distribution algorithm which may utilize the access rates of the documents as a metric for distributing the documents across the servers and determining the redirection probabilities. The load distribution algorithm attempts to equalize the sum of the access rates of all the documents stored at a given document server across all of the document servers. In the event of a server failure, the redirection probabilities may be recomputed such that the load of client requests is approximately balanced among the remaining document servers. The redirection probabilities may also be recomputed periodically in order to take into account changes in document access rates and changes in server capacity. The recomputation may be based on a maximum-flow minimum-cost solution of a network flow problem.
摘要翻译：用于处理通过通信网络接收的客户端请求的服务器系统包括N个文档服务器的集群和至少一个重定向服务器。重定向服务器基于一组预先计算的重定向概率从网络接收客户端请求并将其重定向到其中一个文档服务器。每个文档服务器可以是本地管理一组文档的HTTP服务器，并且可以仅为本地可用文档服务客户端请求。一组文档根据负载分布算法分布在文档服务器上，负载分配算法可以利用文档的访问速率作为跨服务器分发文档的度量并确定重定向概率。负载分配算法尝试均衡所有文档服务器上存储在给定文档服务器上的所有文档的访问速率之和。在服务器发生故障的情况下，可以重新计算重定向概率，使得客户机请求的负载在剩余的文档服务器之间大致平衡。也可以定期重新计算重定向概率，以便考虑文档访问速率和服务器容量变化的变化。重新计算可以基于网络流量问题的最大流量最小成本解决方案。
