cubic中关于t的计算为什么要加上min_rtt

[lonely-wind-nomiss]

cubic_update():
// ......
/*
* t = elapsed_time * 1024 / 1000000, convert microseconds to milliseconds,
* multiply by 1024 in order to be able to use bit operations later.
*/
t = (now + cubic->min_rtt - cubic->epoch_start) << XQC_CUBIC_TIME_SCALE / XQC_MICROS_PER_SECOND;
//....
这个t不应该是now-cubic->epoch_start就可以了嘛，加上了min_rtt是有什么含义呢
