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 translation: 提供了一种示例性方法，包括确定包括发送元件上的分组计数观察与通过链路连接到发送元件的接收元件处的对应分组计数观察之间的时间差的时移; 从所述发送元件获得第一分组计数和从所述接收元件获得第二分组计数; 以及调整所述第一分组计数和所述第二分组计数中的至少一个以补偿所述时间偏移。 该方法还包括比较调整的第一和第二分组计数以确定计数之间是否存在差异，以及如果在计数之间检测到差异，则调整发送元件向接收元件发送分组的速率。
