摘要： A method of workload placement among servers includes receipt of a workload request. The method also includes selection of a group of servers from a set of servers capable of performing the requested workload. In addition, server workload indexes, which are ratios of temperature rises due to re-circulation load for the servers in the group of servers to temperature rises due to re-circulation load for the set of servers, of the servers in the group of servers are calculated. Moreover, the workload is placed on one or more of the servers in the group of servers based upon the server workload indexes of the servers in the group of servers.

摘要： A data service system is described that includes a plurality of data content sites and is coupled to a number of user terminals via a network. The data service system also includes a system for providing performance guarantees for the content sites. The system for providing performance guarantees includes a plurality of class processors, each for controlling access throughput of one of the content sites in accordance with a predetermined admission control policy. When one of the class processors receives an access request for one of the content sites, that class processor determines if the access request should be accepted based on the corresponding admission control policy and sends the access request to the corresponding content site when accepting the access request. The system also includes a classifier that determines to which one of the class processors the access request should be sent. A method of controlling access throughput of the content sites is also described.

摘要： A method and system for caching objects and replacing cached objects in an object-transfer environment maintain a dynamic indicator (Pr(f)) for each cached object, with the dynamic indicator being responsive to the frequency of requests for the object and being indicative of the time of storing the cached object relative to storing other cached objects. In a preferred embodiment, the size of the object is also a factor in determining the dynamic indicator of the object. In the most preferred embodiment, the cost of obtaining the object is also a factor. A count of the frequency of requests and the use of the relative time of storage counterbalance each other with respect to maintaining a cached object in local cache. That is, a high frequency of requests favors maintaining the object in cache, but a long period of cache favors evicting the object. Thus, cache pollution is less likely to occur.
摘要翻译：用于缓存对象并替换对象传送环境中的缓存对象的方法和系统为每个缓存对象维护动态指示符（Pr（f）），动态指示符响应于对象的请求频率，存储缓存对象相对于存储其他缓存对象的时间。在优选实施例中，对象的大小也是确定对象的动态指示符的因素。在最优选的实施例中，获得对象的成本也是一个因素。关于在本地高速缓存中维护缓存的对象，请求的频率的计数和相对于存储的相对时间的使用相互平衡。也就是说，高频率的请求有利于将对象保持在缓存中，但长时间的缓存有利于驱逐对象。因此，缓存污染不太可能发生。

摘要： A system and method for measuring quality-of-service in a federated application environment is described. One or more administrative domains are provided with each administrative domain being interconnected with at least one other administrative domain to form the federated application environment. One or more interconnected network nodes are situated within each administrative domain with each network node including at least one capsule interface within which a managed method is executed. Instrumentation is associated with each capsule interface of each network node with the instrumentation collecting performance data on the managed method being executed within the capsule interface. A count sensor determines a processing time with the instrumentation within the capsule interface for each managed method. A network sensor determines send and receive bandwidth demand information with the instrumentation within the capsule interface for each managed method. A demand sensor determines physical host resource demands as needed to satisfy invocations of the managed method with the instrumentation within the capsule interface for each managed method. An interval sensor determines response times with the instrumentation within the capsule interface for each managed method. A display displays the throughput metrics, bandwidth demand metrics, service demand metrics and response time metrics.

摘要： A measurement system and method of instrumenting a computer program for efficiently monitoring the quality of service in a distributed processing environment are described. A plurality of interconnected network nodes in a computer system with an application process operating on each network node is provided. At least one intelligent sensor is associated with each application process. Each intelligent sensor selectively collects data about at least one of the network node upon which the associated application process operates and the associated application process. An observer is associated with each application process and filters out unchanged and zero values from the data collected by the at least one intelligent sensor. A collector is logically associated with each network node. The intervalized collected data is asynchronously received into the collector periodically pushed from the observer. An analyzer is associated with the distributed processing environment and correlates the intervalized collected data. The intervalized collected data is asynchronously received into the analyzer periodically pushed from the collector.
