摘要： A bandwidth throttling system is implemented on a server network connected to a computer network system to serve one or more clients over a network. The network server supports a service that presents multiple virtual services that can be individually requested by the clients. The bandwidth throttling system controls bandwidth on a per virtual service basis. The bandwidth throttling system has a measuring subsystem to measure the amount of bandwidth being used by each virtual service supported by the network server. The bandwidth throttling system also has a control subsystem to selectively throttle requests for a particular virtual service independently of others based upon the bandwidth used by the particular virtual service. The bandwidth throttling system utilizes an adaptive, hierarchical throttling strategy that is applied to each virtual service independently. The bandwidth throttling system compares the bandwidth usage for the virtual service against the administrator-defined thresholds for that virtual service. If the presently used bandwidth exceeds a first threshold, a first set of throttling actions is applied. If the presently used bandwidth exceeds a second threshold greater than the first threshold, a different second set of throttling actions is applied. In this manner, the administrator is given maximum control at setting throttling policies for each individual virtual service independently of other virtual services.

摘要翻译： 带宽限制系统在连接到计算机网络系统的服务器网络上实现，以通过网络为一个或多个客户端服务。 网络服务器支持提供可以由客户端单独请求的多个虚拟服务的服务。 带宽限制系统在每个虚拟服务的基础上控制带宽。 带宽限制系统具有测量子系统，用于测量由网络服务器支持的每个虚拟服务使用的带宽量。 带宽限制系统还具有一个控制子系统，用于基于特定虚拟服务所使用的带宽，选择性地限制特定虚拟服务的请求，而与其他虚拟服务无关。 带宽限制系统采用独立应用于每个虚拟服务的自适应层级调节策略。 带宽限制系统将虚拟服务的带宽使用与该虚拟服务的管理员定义的阈值进行比较。 如果当前使用的带宽超过第一阈值，则应用第一组节流动作。 如果当前使用的带宽超过大于第一阈值的第二阈值，则应用不同的第二组节流动作。 以这种方式，管理员被给予最大限度的控制，以独立于其他虚拟服务为每个单独的虚拟服务设置限制策略。
