当一个包需要重传的时候，会使用 exponential back-off来计算下一次重传的时间。

这个back-off的使用还是相当的广泛：《Adaptive Backoff Synchronization Technique》https://dl.acm.org/doi/pdf/10.1145/74926.74970
The general idea of backoff has been used in one form or another in a number of applications. The approach was first used in Aloha [l], a radio-based, packet-switching network. If a collision occurred in the network, each source would backoff for a random interval before attempting to retransmit. The Ethernet [16] went one step further and used a random retransmission interval in which collision history influenced the choice of the mean of the random intervals. Adaptive control schemes for multiple access communications networks have been analyzed in [13, 12, 141.
