Perf_client congestion control algorithms

[alexj0l]

Hi community,
I would have some questions regarding perf_client of lsquic:

• Which CCAs are supported by perf_client and can I choose a specific one?
• Which CCA is used as default on perf_client?
• If perf_client supports BBR then which version: 1 or 2?

Thanks a lot in advance!
Kind regards

Anyone any information on that?

I think the choice of CCAs only corresponds to transport layer instead of application layer(perf_client). If you would like to switch default CCAs to others, you could modify the value of LSQUIC_DF_CC_ALGO in lsquic/include/lsquic.h to change it.

/**
 * Congestion control algorithm to use.
 *
 *  0:  Use default (@ref LSQUIC_DF_CC_ALGO)
 *  1:  Cubic
 *  2:  BBRv1
 *  3:  Adaptive (Cubic or BBRv1)
 */
unsigned        es_cc_algo;

From my running perf_client result, bbr is selected。
