Router will abort IP packet when buffer is full and the IP packet is coming in. the tail drop do not use the link enough with TCP/IP's slow start.

当缓冲区满时的丢包策略，最常用的方法是采用尾丢包的方式，而尾丢包的方式和TCP／IP协议的慢启动管理策略会导致全局同步化，给网络带来不良影响，线路利用率不高。

Usually in the process of congestion control there are several methods, in which includes Tail Drop First In Out (TD-FIFO) method and Random Early Detection method (RED).

路由器在处理拥塞时，一般采用尾部丢弃TD-FIFO算法和随机早期丢弃RED算法。通常把网络载荷分为正常、拥塞避免和拥塞三个阶段，并在拥塞避免阶段开始采取行动。

The bird closes its eyes. Just then, a drop of water falls on its head. Then, a second later, another drop falls on its tail.

小鸟闭上眼睛一会儿。就在这个时候，一滴水珠掉在它头上。接着马上又有一滴水落在它的尾巴上。

As the distribution becomes wider they also tend to become skewed with a longer tail towards larger drop sizes.

当分布变宽时，它们往往变得不对称，向较大的液滴尺度一端伸延得更长。

Due to the lack of predictable congestion, the traditional drop tail algorithm could not prevent the congestion collapse.

传统尾丢弃算法由于缺少对拥塞的预知，因此无法防止网络崩溃现象的发生。
