Network out of order

We can process operations out of order and end up with the same result, so we can paper over temporary network and hardware failures, or even replay lost data from minutes or hours ago.

因为能交换操作顺序而不影响最终结果，所以我们才能在网络或者硬件临时故障的时候记录下所有操作或者恢复几分钟甚至几小时之前丢失的数据。

We spread the backups out over a period of several days in order to avoid network and I/O contention.

我们将备份工作分散到几天的时间内，以避免网络和 I/O 争用。

Sometimes, network conditions can cause audio packets to arrive out of order, to be lost in transmission, or to take longer to get to their intended destination than expected.

有时候，网络状况可能导致音频包不能按序到达，或者在传输中丢失，或者比预期花更多的时间到达目的地。
