摘要：
An apparatus includes a difference extraction unit to extract a difference between a second time stamp value, which is obtained by adjusting a first time stamp value that is measured at a time of arrival of a synchronization message transmitted by the master at a Layer 3 to be synchronized in frequency with a clock of the master, and a third time stamp value, which is measured at a time of departure of the synchronization message from the master; a minimum filter to select a minimum from one or more difference values extracted by the difference extraction unit; and a delay variation calculation unit to estimate a time of arrival of a current synchronization message at the Layer 3 based on the selected minimum and calculate a delay variation.

一种装置，包括差分提取单元，用于提取第二时间标记值之间的差异，该第二时间戳值是通过调整由第三层发送的由主机发送的同步消息的到达时所测量的第一时间戳值而获得的 频率与主机的时钟同步，以及第三时间戳值，其在与主机的同步消息的离开时测量; 最小滤波器，用于从由所述差分提取单元提取的一个或多个差值中选择最小值; 以及延迟变化计算单元，基于所选择的最小值来估计当前同步消息在层3的到达时间，并计算延迟变化。
