摘要： A dynamic combined power control and forward error correction control (FEC) technique for mobile radio systems which illustratively decreases the power consumed by wireless transmitters and increases the number of simultaneous connections which may be supported thereby. Individual transmitter-receiver pairs may adaptively determine the minimal power and FEC required to satisfy specified quality-of-service (QOS) constraints. Specifically, in accordance with an illustrative embodiment of the present invention, a first portion of a signal is encoded with a first code to generate a first encoded signal portion. Then, the first encoded signal portion is transmitted with a first power level. Next, parameter data is received, wherein the parameter data is representative of one or more characteristics of a received signal portion having been received by the receiver, the received signal portion having been based on the transmitted first encoded signal portion. A second code and a second power level is then determined based on the received parameter data, and a second portion of the signal is encoded with the second code to generate a second encoded signal portion. Finally, the second encoded signal portion is transmitted with the second power level.

摘要： A method and system for adaptively determining an operating point for a transmitter-receiver pair in a wireless communication network. The receiver receives data over an uplink and measures an average observed word error rate avg.sub.-- WER of the received data and transmits the average observed word error rate avg.sub.-- WER over a downlink to the transmitter when the average observed word error rate avg.sub.-- WER is not within an acceptable word error rate range. The transmitter receives the average observed word error rate avg.sub.-- WER over the downlink and determines a power-code pair (P,c) for the transmitter based on the average observed word error rate avg.sub.-- WER. The power code pair (P,c) defines an operating point of the transmitter, where P of the power-code pair is a selected transmit power level of the transmitter and c of the power-code pair is a selected forward error correcting code used for encoding the data. The receiver can also determine a predicted word error rate WER.sub.pred for a first timeframe based on the observed word error rate WER.sub.obs for a second timeframe, and determines whether the predicted word error rate WER.sub.pred is within the acceptable word error rate WER range.

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。

摘要： The present disclosure is based on a multi-core or multi-processor virtualized environment that comprises both time-sensitive and non-time-sensitive tasks. The present disclosure describes techniques that use a plurality of criteria to choose a processing resource that is to execute tasks. The present disclosure further describes techniques to re-schedule queued tasks from one processing resource to another processing resource, based on a number of criteria. Through load balancing techniques, the present invention both (i) favors the processing of soft real-time tasks arising from media servers and applications, and (ii) prevents “starvation” of the non-real-time general computing applications that co-exist with the media applications in a virtualized environment. These techniques, in the aggregate, favor the processing of soft real-time tasks while also reserving resources for non-real-time tasks. These techniques manage multiple processing resources to balance the competing demands of soft real-time tasks and of non-real-time tasks.

摘要： A feature activation system provides a mixed computing environment that includes a server and cloud computing. The hybrid model splits the execution of a communication feature between the cloud and the enterprise server installed at or with the enterprise. Service activation is linked to a portal that can communicate with either an intermediary system or directly with an entity executing computer programs in the cloud. When the customer desires to use a feature, the customer accesses the portal and activates the feature the enterprise desires. In the background, the portal instantiates a virtual machine, on any cloud platform, and then installs the feature with virtual machine on that cloud server. To execute feature, the enterprise server and the virtual machine exchange information between the server and the cloud and allow the feature to access the enterprise server or enterprise data. When the user has completed feature execution, the instance of the feature may be stopped and discarded and any data may be saved either at the enterprise or within the cloud.
