Eliminating VBR would increase network congestion, bringing data-buffers into play to deal with information overflow and underflow.

摒弃可变比特率将会加重网络拥塞，需要使用数据缓冲区来处理信息流过大或过小的问题。

However, if it collides again, which suggests network congestion, instead of waiting another 1 second, this time it will wait 2 seconds.

但是，如果它再次碰撞，这表明网络拥塞，而不是再等待 1 秒，这次它将等待 2 秒。

Interestingly, the success rate of ACKs, and also the round trip time between sending and acknowledging, can be used to infer network congestion.

有趣的是，ACK 的成功率以及发送和确认之间的往返时间可用于推断网络拥塞。
