    • A system and method by which content, such as a software update, is downloaded in a controlled manner to clients so as to reduce peak demands, by modulating the number of clients that can request (e.g., automatically) to download content. To this end, before any download is requested, each client receives information that the client uses to determine whether to request the content now, or back off and retry the download process later. In one implementation, the information is provided via a download regulation file, comprising acceptance percentage and time window parameters that are occasionally varied based on current network load-related statistics. Clients generate a random number that is evaluated against the acceptance percentage (probability threshold) to determine whether to download or back off. The time window specifies how long downloading clients are allowed to download, or how long backed-off clients need to wait before restarting the regulated download process.
    • 通过调整可以请求(例如,自动)下载内容的客户端的数量,通过该方式将诸如软件更新的内容以受控的方式下载到客户端以减少峰值需求。 为此,在请求任何下载之前,每个客户端都会收到客户端用于确定是否立即请求内容的信息,或者退回并稍后重试该下载过程。 在一个实现中,通过下载规则文件提供信息,包括接收百分比和时间窗参数,这些参数偶尔会根据当前网络负载相关的统计信息而变化。 客户端生成一个随着接收百分比(概率阈值)评估的随机数,以确定是否下载或退出。 时间窗口指定下载客户端允许下载多长时间,或客户端在重新启动受规定的下载过程之前需要等待多长时间。
