CUBIC Congestion Control

This implementation is based on the following draft: https://tools.ietf.org/html/draft-ietf-tcpm-rfc8312bis-02 (opens new window)

Note that Slow Start can use HyStart++ when enabled.

Delivery rate estimation.

This implements the algorithm for estimating delivery rate as described in https://tools.ietf.org/html/draft-cheng-iccrg-delivery-rate-estimation-01 (opens new window)

HyStart++

This implementation is based on the following I-D:

Proportional Rate Reduction

This implementation is based on the following RFC:

https://datatracker.ietf.org/doc/html/rfc6937 (opens new window)

PRR 算法(Proportional Rate Reduction)决定在丢包恢复（Loss Recovery）期间，对应于每个 ACK 报文，可发送的报文数量。 目的是：1）快速平稳的从 Loss 中恢复；2）恢复之后拥塞窗口收敛与 ssthresh

Reno Congestion Control

Note that Slow Start can use HyStart++ when enabled.
