因为队列的大小没有界限，使得添加可以立即返回，但是在延迟时间过去之前，不能从队列中取出元素。

The number of packets in the retransmission queue is fundamentally driven by the bandwidth delay product (BDP) between the two hosts.

重传队列中包的数目基本上取决于两台主机间的带宽延迟效果（bandwidth delay product，BDP）。

It is a specific type of BlockingQueue: getting an item from the queue will block until the delay has passed, if an item isn't available immediately.

它是一种特定类型的BlockingQueue：如果一个项不可用，则从队列获取该项会受到阻止，直到延迟失效。
