摘要： Communication traffic isolation and control systems and methods are disclosed. Communication traffic streams are received and either passed or filtered by respective controllable filtering modules. The operation of the filtering modules is controlled on a per-module and thus a per-stream basis, responsive to congestion of filtered communication traffic streams at a communication traffic processing element to which the filtering modules are connected. Per-stream filtering provides traffic control for each communication traffic stream, and maintains isolation between the streams. Statistics associated with communication traffic filtered out of each stream may be collected, and possibly aggregated.

摘要： Communication traffic management systems and methods are disclosed. A threshold status of a communication traffic queue of a second communication traffic management device which is capable of receiving communication traffic from a first communication traffic management device is determined, by comparing a depth of the queue to a corresponding threshold for instance. A rate of transfer of communication traffic to the second device, and possibly to particular queues of the second device from corresponding queues of the first device, is controlled based on the threshold status. Transmission of communication traffic from the queues of the second device may thus be in accordance with one communication traffic management scheme, whereas the content of each queue of the second device is controlled according to another communication traffic management scheme used by the first device to transfer communication traffic from its queues, to thereby provide for complex combined communication traffic management.

摘要： The backpressure mechanism and method described here do not completely shut off the traffic when a queue is experiencing congestion. Instead of completely shutting off the traffic and waiting for the effects, a series of backpressure pulses are sent to the upstream stage for intermittently slowing the traffic between the upstream and downstream stages. These pulses of backpressure effectively slowly down the rate of the ingress traffic to the queue to a rate less than the egress rate. This allows queue utilization to slowly decrease. These pulses continue as long as the queue utilization is above a threshold called “Starving Threshold”. This technique allows much lower queue utilization, thus requiring smaller queues sizes.
摘要翻译：当队列遇到拥塞时，这里描述的背压机制和方法并不完全关闭流量。不是完全关闭流量并等待效果，而是将一系列背压脉冲发送到上游级，以间歇地减慢上游和下游级之间的流量。这些背压脉冲有效地缓慢地将进入队列的速率降低到小于出口速率的速率。这允许队列利用率缓慢降低。只要队列利用率高于称为“饥饿阈值”的阈值，这些脉冲就会持续。这种技术允许较低的队列利用率，因此需要较小的队列大小。
