    Abstract: Various implementations disclosed herein enable congestion control systems and methods that are agnostic of the availability of congestion notification types, and are simultaneously responsive to multiple types of network congestion indicators—including both implicit (e.g., loss and delay) and explicit (e.g., marking) congestion indicators. For example, some implementations include a congestion control method that includes obtaining a composite congestion indicator value associated with multiple types of network congestion indicators, and determining a reference rate value based on a function of the composite congestion indicator value. The composite congestion indicator value represents a combination of one or more delay values associated with respective types of network congestion indicators. The reference rate value is representative of a baseline transmission rate from the first device that at least partially mitigates network congestion signaled by the network congestion indicators.

    Abstract: An example method is provided and includes determining a time shift comprising a difference in time between a packet count observation at a transmit element and a corresponding packet count observation at a receive element connected to the transmit element via a link; obtaining a first packet count from the transmit element and a second packet count from the receive element; and adjusting at least one of the first packet count and the second packet count to compensate for the time shift. The method further includes comparing the adjusted first and second packet counts to determine whether there is a discrepancy between the counts and if a discrepancy is detected between the counts, adjusting a rate at which the transmit element sends packets to the receive element.

    Abstract: In one implementation, an input queue switch provides latency fairness across multiple input ports and multiple output ports. In one embodiment, each input port maintains a virtual output queue for each associate output port. The virtual output queues across multiple inputs are aggregated for each specific output port. The sum of the lengths of the virtual output queues is compared to a threshold, and based on the comparison, feedback may be generated to control the operation of the input port for subsequent packets. The feedback may instruct the input port to stop buffering or drop packets destined for the output port with the sum of the lengths of the virtual output queues associated to the specific output port that exceeds the threshold. In another embodiment, each packet has an arrival timestamp, and a virtual output queue having the oldest timestamp is selected first to dequeue.

    Abstract translation: 在一个实现中，输入队列交换机提供跨多个输入端口和多个输出端口的延迟公平性。 在一个实施例中，每个输入端口维护每个关联输出端口的虚拟输出队列。 跨多个输入的虚拟输出队列针对每个特定输出端口进行聚合。 将虚拟输出队列的长度的总和与阈值进行比较，并且基于比较，可以生成反馈以控制后续分组的输入端口的操作。 反馈可以指示输入端口以与超过阈值的特定输出端口相关联的虚拟输出队列的长度的总和来停止缓冲或丢弃目的地为输出端口的分组。 在另一个实施例中，每个分组具有到达时间戳，并且首先选择具有最早时间戳的虚拟输出队列以出队。
