Abstract: Systems and methods are provided that enable flow aware buffer management. The method includes storing in a queue of a buffer a first type of traffic, storing in the queue of the buffer a second type of traffic, wherein the first type of traffic is less sensitive to latency than the second type of traffic, and when an amount of the first type of traffic meets or exceeds a first threshold, effecting flow control of the first type of traffic to slow a flow of the first type of traffic into the buffer. Flow control can be effected using packet marking or discarding packets. The methodology has particular utility in connection with managing elephant and mouse flows in a network switch.

Abstract translation: 提供了启用流感知缓冲区管理的系统和方法。 该方法包括在缓冲器的队列中存储第一类型的业务，在缓冲器的队列中存储第二类型的业务，其中第一类型的业务对第二类型业务的等待时间较不敏感，并且当 第一类型的流量的量满足或超过第一阈值，实现第一类型的流量的流量控制，以将第一类型的流量的流量减慢到缓冲器中。 可以使用分组标记或丢弃分组来实现流控制。 该方法对于在网络交换机中管理大象和鼠标流具有特别的实用性。
