A QoS-Based Fairness-Aware BBR Congestion Control Algorithm Using QUIC

Algorithm 1

Enhanced BBR Congestion Control Algorithm.

Input:, Time, targetCwnd.

Output:Throughput, delay.

Time: the total time of transmission;

diff: the extra packets in the queue;

: the packet loss signal;

1: Initialize

2: whiledo

3: ifdiff < and = false and in ProbeBW state then

4:  keep in ProbeBW state

5:  

6: elseifdiff >= and = false and in ProbeBW state then

7:  keep in ProbeBW state

8:  

9: elseifdiff >= and = true and in ProbeBW state then

10:  change to ProbeRTT state

11: elseifdiff >= and = true and in ProbeRTT state then

12:  

13: end if

14: end while

15: returnThroughput, delay.
