Hi Sebastian,

Thanks for the great work.
Some comments/questions.

  *   Sec. IV,D, 5: Interesting to know "picoquic" does speculative retransmission. As you argue, this may not always help. Did you confirm with the author?
  *    The results show loss-based CC does not perform well compared to BBR
  *   Production software performs well more like picoquic or not ?
     *   how big difference is between production vs these implementations in the test?
  *   Any Time-Offset graphs for EUTELSAT case ?
  *   Research overview page: additional column on emulated or real Sat link will be helpful

Good useful work.
thanks.

Dear all,

we've published a pre-print of our paper in which we present the QUIC-Interop-runner extended to include satellite scenarios and our measurement results using numerous publicly available QUIC implementations:

https://urldefense.com/v3/__https://arxiv.org/abs/2202.08228__;!!Emaut56SYw!mFvp0jheUG95wMrw7L6ZHr3AUjZZgp63MEXhAZnEYvwEkQITw9uIFauoKkW-JRj-Kg$

Best regards,

Sebastian
