    • An apparatus and method for distributing traffic across a group of machines using application instance statistics. In order to perform load balancing in accordance with the present invention, a method of generating weights to bias load balancing distributions is provided. The application instances to which traffic is being distributed, or the application middleware, are instrumented to establish certain metrics about the application while running. The application instance instrumentation will provide application statistics such as number of successful transactions, application response times, application topology, importance of transactions being processed, time the application is blocked waiting for resources, resource consumption data, and the like. These metrics are collected, processed, and then presented as a set of weights to the load balancing apparatus to govern its distribution of traffic. With such application metrics available, traffic can be disbursed based on the current state of the application instances and other application instances in the transaction's path, the application instance's likelihood to complete the request, or even higher level business-oriented goals.
    • 一种用于使用应用程序实例统计信息在一组机器上分配流量的装置和方法。 为了根据本发明执行负载平衡,提供了一种产生权重以偏置负载均衡分布的方法。 要分发流量的应用程序实例或应用程序中间件被运行,以便在运行时建立应用程序的某些指标。 应用程序实例仪器将提供应用程序统计信息,例如成功事务的数量,应用程序响应时间,应用程序拓扑,正在处理的事务的重要性,应用程序被阻止等待资源的时间,资源消耗数据等。 这些度量被收集,处理,然后作为一组权重呈现给负载平衡装置以管理其流量分布。 通过这种应用指标,可以根据交易路径中应用程序实例和其他应用程序实例的当前状态,应用程序实例完成请求的可能性,甚至更高级别的面向业务的目标来支付流量。

    • Managing processor resources in a non-dedicated computer system. An amount of a processor resource is allocated to a real-time application of the computer system. The amount does not exceed a limit chosen for a group of real-time applications, wherein the group includes the real-time application being allocated the resource. A selected amount of the processor resource remains available to execute other types of applications and work on the system. During processing of the real-time application, use of the processor resource does not exceed a chosen maximum value, thereby ensuring the processor resource is not monopolized by the real-time application and allowing other types of work to be processed on the system.
    • 在非专用计算机系统中管理处理器资源。 处理器资源的数量被分配给计算机系统的实时应用程序。 该量不超过为一组实时应用选择的限制,其中该组包括被分配资源的实时应用。 所选择的处理器资源量仍然可用于执行其他类型的应用程序并在系统上工作。 在处理实时应用程序期间,使用处理器资源不会超过选定的最大值,从而确保处理器资源不被实时应用程序所垄断,并允许在系统上处理其他类型的工作。
