摘要： Methods, apparatuses and systems directed to an aggregate bandwidth utilization control scheme including fair share bandwidth allocation and dynamic allocation of bandwidth in response to detected traffic utilization. In one implementation, the present invention includes a weighted, fair share aggregate bandwidth allocation mechanism that dynamically responds to observed bandwidth utilization to provide unutilized or excess bandwidth to flows and partitions that require it. In another implementation, the present invention features a weighted fair share allocation scheme for hierarchical partition configurations. In other implementations, the present invention provides a per-flow target rate assignment mechanism that prevents spiraling decline of data flow rates.

摘要： An example embodiment of the invention provides a process for lockless processing of hierarchical bandwidth partitions configurations in multiple processor architectures. In one embodiment, the process runs in an NPU's data plane and receives a packet for a partition from a child partition through a work queue. The process determines a suggested target bandwidth rate for the receiving partition's child partitions, based in part on a count of active child partitions, if a predefined time interval has passed. The process adopts a target bandwidth rate for the receiving partition suggested by the receiving partition's parent partition, if the receiving partition is not a root partition and the predefined time interval has passed. The process then transmits the packet to the receiving partition's parent partition through the work queue, if the receiving partition is not a root partition. Otherwise, the process transmits the packet to a port.
摘要翻译：本发明的示例实施例提供了一种用于在多处理器架构中的分层带宽分区配置的无锁处理的过程。在一个实施例中，该过程在NPU的数据平面中运行，并通过工作队列从子分区接收分区的分组。如果预定义的时间间隔已经过去，则该过程部分地基于活动子分区的计数来确定接收分区的子分区的建议的目标带宽速率。该过程采用接收分区的父分区建议的接收分区的目标带宽率，如果接收分区不是根分区，并且预定义的时间间隔已过。然后，如果接收分区不是根分区，则进程通过工作队列将数据包发送到接收分区的父分区。否则，该过程将数据包发送到端口。

摘要： Packet flow rate control techniques are enhanced by the interactive and early invocation of packet queuing to control short flows of packets and to eliminate undershoot and overshoot of a targeted flow rate. Packet queuing involves the scheduled release of packets in accordance with flow policies (priorities) to achieve a preselected outgoing target flow rate. The combination of controlled packet queuing and packet flow rate control with appropriate mechanisms for favoring one over the other improves the efficiency of data transmission.
