    • In one embodiment, a method is provided for congestion mitigation. In this method, a congestion level of data flows along a path is monitored relative to a threshold. Here, each data flow is associated with a flow identifier. Based on detection that the congestion level exceeds the threshold, the flow identifier of a number (e.g., one or more) of the data flows is changed to a different flow identifier. This change results in the number of the data flows redirected to a different path. In an alternate embodiment, another method is provided for congestion avoidance. In this method, a data flow transmitted along a single path is received, and the data flow is split into multiple micro data flows. A different flow identifier is then assigned to each micro data flow. This change results in the multiple micro data flows distributed along multiple different paths.
    • 在一个实施例中,提供了一种用于拥塞缓解的方法。 在该方法中,相对于阈值监视沿着路径的数据流的拥塞级别。 这里,每个数据流与流标识符相关联。 基于拥塞级别超过阈值的检测,数据流(例如,一个或多个)的流标识被改变为不同的流标识符。 此更改导致重定向到不同路径的数据流的数量。 在替代实施例中,提供了另一种用于拥塞避免的方法。 在该方法中,接收沿着单个路径发送的数据流,并将数据流分割为多个微数据流。 然后将不同的流标识符分配给每个微数据流。 这种变化导致沿着多个不同路径分布的多个微数据流。

    • A fault protection and correction circuit for the control of a power converter is disclosed. An example circuit generates a waveform that drives a switch on or off and controls the power converter. The controller circuit in addition to power factor correction (PFC) circuitry includes a first and a second shut down mode modules, both of them cause the switching to stop. The circuit includes a module for receiving fault events. When a fault occurs, the controller enters the second shut down mode. The controller stays in the second shut down mode if the required current for this mode can be provided by the outside circuitry. Otherwise, the controller enters the first shut down mode that requires less current and subsequently restarts the controller. By modifying the outside circuitry the controller can respond differently to fault events.
    • 公开了一种用于控制功率转换器的故障保护和校正电路。 示例电路产生驱动开关打开或关闭并控制功率转换器的波形。 除了功率因数校正(PFC)电路之外,控制器电路包括第一和第二关断模式模块,它们都导致切换停止。 该电路包括用于接收故障事件的模块。 当发生故障时,控制器进入第二个关闭模式。 如果外部电路可以提供该模式所需的电流,则控制器保持在第二关闭模式。 否则,控制器进入需要较少电流的第一关闭模式,然后重新启动控制器。 通过修改外部电路,控制器可以对故障事件做出不同的响应。
