    Abstract: A device includes a multistage filter and an elephant trap. The multistage filter has hash functions and an array. The multistage filter is operable to receive a packet associated with a candidate heavy network user and send the packet to the hash functions. The hash functions generate hash function output values corresponding to indices in the array. The elephant trap is connected to the multistage filter. The elephant trap includes a buffer and probabilistic sampling logic. The probabilistic sampling logic is operable to attempt to add information associated with the packet to the buffer a particular percentage of the time based in part on the result of the multistage filter lookup. The buffer is operable to hold information associated with the packet, counter information, and timestamp information.

    Abstract: In one implementation, a network device is configured to implement an intra switch transport protocol. The intra switch transport protocol is configured to determine a window size according to a predetermined bandwidth and a round trip time between a plurality of ingress ports and an egress port. The network device is configured to sending at least one data packet from an ingress port to an egress port without first receiving any acknowledgement from the egress port. The network device continues to send packets and increment a counter accordingly until the counter reaches the window size. The network device ceases transmission of subsequent data packets and/or queues subsequent data packets based on the counter exceeding the window size.

    Abstract translation: 在一个实现中,网络设备被配置为实现帧内交换传输协议。 内部交换机传输协议被配置为根据预定带宽和多个入口端口和出口之间的往返时间来确定窗口大小。 网络设备被配置为在不首先从出口端口接收到任何确认的情况下将至少一个数据分组从入口端口发送到出口端口。 网络设备继续发送数据包并相应递增计数器,直到计数器达到窗口大小。 网络设备基于超过窗口大小的计数器停止后续数据分组的传输和/或排队后续数据分组。
