为了对失序数据包进行重排序，应用程序需要预留一个适当的缓冲区以存储期望包到达之前的数据包。
To rearrange the out of order packets, the application software must reserve a buffer to store the packets before the expected packet arrives.
颤抖缓冲的目标就是将它们缓冲到足够长（不跨越必须的）并对这些包进行重排序，然后才送给进行解码。
The purpose of a jitter buffer is to reorder packets and buffer them long enough (but no longer than necessary) so they can be sent to be decoded.
